What is Metered dose inhaler MDI: Uses, Safety, Operation, and top Manufacturers!

Introduction

Metered dose inhaler MDI is a widely used respiratory drug-delivery platform designed to deliver a metered (pre-measured) amount of medication to the airways as an inhaled aerosol. In day-to-day practice it sits at the intersection of pharmacy, nursing, respiratory therapy, and clinical engineering: it is both a medication container and a patient-facing delivery medical device.

For hospitals and clinics, Metered dose inhaler MDI matters because it can support rapid administration, bedside portability, and standardized dosing without electrical power or complex hospital equipment. It also introduces operational risks that are easy to underestimateโ€”technique dependence, lookโ€‘alike products, deviceโ€“drug pairing issues, cleaning and cross-contamination concerns, and supply variability across regions.

This article provides general, non-clinical guidance for administrators, clinicians, biomedical engineers, and procurement teams on what Metered dose inhaler MDI is, where it fits in care pathways, what to check before use, how basic operation typically works, how to think about safety and infection control, how to troubleshoot common failures, and how the global market differs by country. It also explains how manufacturers and OEM relationships affect quality and support, and what distributors typically do in the healthcare supply chain.

What is Metered dose inhaler MDI and why do we use it?

Metered dose inhaler MDI (often abbreviated โ€œMDIโ€) is a pressurized canister-and-actuator system that releases a controlled volume of medication formulation with each actuation. The device typically consists of:

  • A pressurized canister containing drug plus propellant (and sometimes co-solvents/excipients)
  • A metering valve that controls the delivered volume per actuation
  • A plastic actuator/mouthpiece that directs the aerosol plume
  • Sometimes a dose counter (varies by manufacturer)

Because Metered dose inhaler MDI delivers medication directly to the respiratory tract, it is used for drugs intended to act in the lungs (and, in some cases, with systemic absorption). In many regulatory frameworks it is treated as a drugโ€“device combination product: the medication and the delivery clinical device are evaluated together, and the actuator can be considered part of the โ€œsystemโ€ that affects dose delivery.

Common clinical settings for Metered dose inhaler MDI

In hospitals and outpatient settings, Metered dose inhaler MDI is commonly encountered in:

  • Emergency departments and urgent care for rapid bronchodilator delivery (per local protocols)
  • Inpatient wards for scheduled and as-needed inhaled therapy
  • ICU and perioperative areas, including use with adapters in ventilated patients (policy- and manufacturer-dependent)
  • Pulmonology, allergy, and primary care clinics for ongoing management and technique assessment
  • Discharge planning workflows where education, reconciliation, and access planning matter

Why healthcare systems choose this medical device

Key reasons Metered dose inhaler MDI is widely used as medical equipment include:

  • Portability and speed: no compressor, no power source, minimal setup time compared with many nebulizer workflows
  • Metered delivery: each actuation is designed to deliver a consistent volume from the metering valve (actual lung delivery still depends heavily on technique)
  • Workflow efficiency: often faster to administer at the bedside and easier to store/transport than bulkier hospital equipment
  • Lower infrastructure burden: no need for oxygen flow meters or compressors solely for medication delivery (depending on clinical context)
  • Scalability: in high-volume settings, standardized processes and training can reduce variability

Operational and clinical limitations to keep in view

Metered dose inhaler MDI is not โ€œset-and-forgetโ€ hospital equipment. Common limitations include:

  • Technique dependence: coordination, inhalation flow, and timing strongly influence deposition
  • Deviceโ€“drug specificity: actuators, canisters, and accessories are not always interchangeable; mixing components can alter delivered dose (varies by manufacturer and product)
  • Dose tracking: not all devices have dose counters; tracking remaining doses can be operationally challenging
  • Environmental and storage constraints: pressurized containers require safe storage and disposal controls
  • Training load: staff and patient technique must be reinforced, particularly across transitions of care

When should I use Metered dose inhaler MDI (and when should I not)?

This section provides general context only. Decisions about medication choice, dosing, and appropriateness are clinical decisions governed by local policy, clinician judgment, and the manufacturerโ€™s instructions for use (IFU).

Appropriate use cases (general)

Metered dose inhaler MDI is typically used when:

  • The prescribed medication is supplied in an MDI format and local formulary supports it
  • A portable, bedside-ready delivery method is required
  • The patient can follow instructions for coordinated inhalation and actuation, or the facility can support use with appropriate accessories (for example, a spacer/valved holding chamber)
  • A facility aims to standardize inhaled therapy workflows across units (ED, wards, outpatient)
  • The care pathway benefits from reduced equipment logistics compared with some nebulizer setups (for example, fewer components to source, clean, and maintain)

In many health systems, Metered dose inhaler MDI is also used strategically to support infection-control priorities and to reduce equipment turnaround timeโ€”provided staff competency and cleaning controls are strong.

Situations where it may not be suitable

Metered dose inhaler MDI may be less suitable when:

  • The patient cannot coordinate inhalation and actuation and no suitable assistive device is available
  • The patient cannot achieve a reliable mouth seal (without a mask interface that is compatible and approved)
  • The patient is intubated or receiving ventilatory support without an approved adapter and a validated protocol
  • The clinical situation requires a different delivery platform (for example, continuous delivery needs or medications not available as MDI)
  • The device is expired, damaged, contaminated, or missing essential components (cap, actuator integrity, correct labeling)
  • The facility cannot ensure single-patient assignment or safe โ€œshared canisterโ€ workflows (if used locally) without cross-contamination risk

General safety cautions and contraindication themes (non-clinical)

Most formal contraindications relate to the medication, not the actuator itself. For safety-focused operational teams, recurring caution themes include:

  • Pressurized container hazards: avoid puncture, crushing, exposure to high heat, and improper disposal; follow manufacturer guidance
  • Fire and ignition risk: propellants and sprays can be flammable in certain conditions; avoid use near open flames and follow oxygen/fire safety policies
  • Cross-patient contamination: the mouthpiece is a patient-contact surface; policies should clearly define whether MDIs are single-patient and how accessories are handled
  • Component mixing: avoid using a canister with a different actuator unless the manufacturer explicitly states compatibility
  • Look-alike/sound-alike risk: similar canister shapes and labeling can contribute to medication errors without strong storage and barcode controls

What do I need before starting?

Successful use of Metered dose inhaler MDI depends as much on preparation and governance as on the actuation itself. Hospitals that treat it like routine โ€œsmallโ€ equipment often see preventable variability.

Required setup, environment, and accessories

Common prerequisites include:

  • Correct product: right medication, strength, and device presentation per order and formulary
  • Correct actuator and canister pairing: do not assume intercompatibility across brands or even within a brand family
  • Spacer/valved holding chamber (VHC) when indicated by local protocols or patient needs (compatibility varies by manufacturer)
  • Appropriate interface: mouthpiece or mask (especially in pediatrics or patients unable to seal lips)
  • Personal protective equipment (PPE) aligned with local respiratory isolation policies
  • Waste disposal pathway for caps, packaging, and end-of-life canisters (pressurized container policies often apply)

Environmental preparation should usually include:

  • A position that supports upright posture when feasible
  • Adequate lighting for label verification and dose counter reading
  • A plan for privacy and patient coaching, especially during first-dose education in outpatient or discharge settings

Training and competency expectations

For hospitals and clinics, Metered dose inhaler MDI competency is not โ€œcommon sense.โ€ Practical expectations often include:

  • Device-specific technique training for nursing, physicians, and respiratory therapists (and refreshers when products change)
  • Teach-back workflows for patients and caregivers, documented per facility policy
  • Standardized scripts/checklists to reduce staff-to-staff variability
  • Awareness of product differences (dose counters, priming needs, shaking needs, mouthpiece geometry, breath-actuated variants)

Biomedical engineers are not typically โ€œrepairingโ€ Metered dose inhaler MDI canisters, but they may support governance of accessory devices (spacers, masks, adapters), training materials, and incident trending.

Pre-use checks and documentation

A practical pre-use check for Metered dose inhaler MDI commonly includes:

  • Confirm right patient / right medication / right route per local medication safety processes
  • Inspect packaging and label for name, strength, and expiry
  • Check dose counter if present; if not present, confirm facilityโ€™s tracking method
  • Inspect mouthpiece/actuator for debris, cracks, residue, or damage
  • Confirm the canister is properly seated in the actuator
  • Confirm whether priming is required (varies by manufacturer and time since last use)
  • Confirm whether shaking is required (varies by manufacturer and formulation type)

Documentation practices vary widely by country and facility. Common documentation elements include:

  • Number of actuations delivered (noting that priming actuations may also decrement counters; varies by manufacturer)
  • Lot/batch tracking when required by policy
  • Patient education provided and technique assessment outcomes (especially in outpatient and discharge workflows)
  • Cleaning/assignment status for any spacer/VHC or mask

How do I use it correctly (basic operation)?

The core operational principle of Metered dose inhaler MDI is simple: each actuation releases a metered volume of formulation that becomes an aerosol plume. What makes real-world performance variable is timing, inhalation flow, priming status, and accessory use.

The workflow below is a general reference. Always follow the manufacturer IFU and facility protocols.

Basic step-by-step workflow (generic)

  1. Verify the medication, strength, patient, and expiration; confirm the inhaler is the intended product.
  2. Perform hand hygiene and don PPE as indicated by local policy.
  3. Remove the cap and inspect the mouthpiece for dust, lint, or visible residue.
  4. Confirm the canister is fully inserted into the actuator and is not loose.
  5. If required, shake the inhaler (some products require shaking; others may notโ€”varies by manufacturer).
  6. If required, prime the inhaler (especially when new, dropped, cleaned, or not used for a period; priming instructions vary by manufacturer).
  7. Ask the patient to position for effective inhalation (commonly upright when feasible), and explain the steps.
  8. If using direct mouthpiece technique: the patient forms a tight seal with lips around the mouthpiece.
  9. The patient begins a controlled inhalation, and the clinician/patient actuates the device per technique guidance in the IFU.
  10. The patient continues inhalation and then performs a brief breath hold if tolerated and instructed by local training materials (exact duration varies by manufacturer and clinical protocol).
  11. If more than one actuation is ordered, wait the recommended interval before repeating (interval guidance varies by medication and manufacturer).
  12. Replace the cap, store the device per policy, and document administered actuations and any technique notes.

Using a spacer or valved holding chamber (VHC)

A spacer/VHC can reduce coordination demands and may improve consistency for some patients. General workflow differences include:

  • Confirm the spacer/VHC is compatible, clean, and assigned per infection-control policy.
  • Attach the Metered dose inhaler MDI actuator to the spacer/VHC correctly (orientation matters).
  • Actuate into the chamber per IFU; the patient then inhales from the chamber per the spacerโ€™s instructions.
  • For mask interfaces, ensure a secure seal; some protocols allow multiple breaths per actuation (varies by manufacturer and clinical protocol).

Operational notes for hospitals:

  • Spacers/VHCs are often the โ€œhidden variableโ€ in performance: static charge, moisture, and cleaning residues can affect aerosol behavior. Handling guidance varies by manufacturer.
  • Facilities should standardize which spacer models are stocked to reduce training burden and procurement complexity.

Breath-actuated variants and add-on aids

Some products marketed as Metered dose inhaler MDI may include breath-actuated mechanisms or accessories that help timing. If used:

  • Ensure staff can identify the product type quickly (labeling and cap shape may differ).
  • Confirm any โ€œclickโ€ or indicator behavior in training materials; do not assume it functions like a standard press-and-breathe MDI.

Calibration and โ€œsettingsโ€: what applies and what usually does not

Unlike many hospital equipment categories, Metered dose inhaler MDI generally:

  • Does not have user calibration in the traditional biomedical engineering sense.
  • Delivers a metered volume determined by the valve and formulation; users cannot adjust delivered micrograms directly.

What users can typically control operationally includes:

  • Number of actuations administered (per order)
  • Use of accessories (spacer/VHC, mask, ventilator adapter)
  • Technique parameters (timing, seal quality, inhalation pattern) via training

If a product includes electronic tracking, reminders, or connectivity (โ€œsmart inhalerโ€ features), available settings and outputs vary by manufacturer and may be managed through institutional digital health policies.

Storage and handling during use

Practical handling controls for Metered dose inhaler MDI include:

  • Keep away from excessive heat and direct sunlight; storage ranges vary by manufacturer.
  • Avoid dropping; cracks in the actuator can change plume direction and dosing consistency.
  • Keep the mouthpiece capped between uses to reduce contamination with lint or fluids.

How do I keep the patient safe?

Patient safety with Metered dose inhaler MDI is primarily about preventing medication errors, ensuring consistent delivery technique, and managing infection-control and environmental hazards.

Safety practices and monitoring (general)

Common system-level safety practices include:

  • Barcode medication administration (BCMA) or equivalent verification where available
  • Standardized storage segregation to reduce selection errors (e.g., separate bins for different drug classes)
  • Clear labeling for patient-specific assignment when devices are issued for individual use
  • Routine checks that the device is not empty and has not exceeded labeled use (dose counter or facility tracking method)
  • Documentation of education and technique assessment at key transitions (admission, unit transfer, discharge)

Monitoring practices depend on the medication and clinical scenario. In general operational terms:

  • Observe for unexpected deterioration after administration and follow emergency response protocols.
  • Monitor for anticipated medication effects per local clinical pathways (drug-class dependent).

Human factors: where errors happen in real life

Hospitals often see repeatable failure modes with Metered dose inhaler MDI:

  • Look-alike canisters and caps in medication drawers or automated dispensing cabinets
  • โ€œBorrowingโ€ an actuator or spacer from another patient due to shortages or workflow pressure
  • Staff assuming all MDIs require the same technique (shaking, priming, breath hold)
  • Misinterpretation of a dose counter โ€œnear emptyโ€ range or failure to account for priming actuations
  • Use of a canister with the wrong actuator, potentially altering delivered dose (compatibility varies; do not interchange unless stated)

Mitigations that scale include:

  • Standardized unit-based inhaler kits (device + compatible spacer + instruction card)
  • Competency check-offs for staff and inclusion in onboarding for new clinicians
  • A simple โ€œstop and verifyโ€ step when changing brands due to supply substitutions

Alarm handling and related equipment considerations

Metered dose inhaler MDI itself typically has no audible alarms. However:

  • Devices with dose counters provide a visual indicator that can be treated as an โ€œalarm equivalentโ€ for low remaining doses.
  • When used in mechanically ventilated patients (where permitted), clinicians may see changes in ventilator waveforms or alarms unrelated to the inhaler; these must be managed per ventilator protocols.

Special safety considerations: pressurized container and oxygen environments

Operationally important points include:

  • Treat the canister as a pressurized container: do not puncture, crush, or incinerate; follow local hazardous waste guidance.
  • Avoid use near ignition sources; reinforce โ€œno smokingโ€ and oxygen/fire safety policies.
  • Avoid directing the plume toward eyes; train staff on safe handling even during urgent administration.

How do I interpret the output?

Unlike monitoring devices that produce numeric physiological outputs, Metered dose inhaler MDI offers limited direct โ€œreadouts.โ€ Interpretation is largely about device status and administration integrity.

Types of outputs or indicators you may encounter

Depending on product design, outputs may include:

  • Dose counter readings (e.g., numeric countdown, color bands, or window indicators; varies by manufacturer)
  • Tactile and audible cues during actuation (clicks, resistance)
  • Visible plume characteristics (shape and strength), which can be misleading if used alone
  • For certain add-ons: electronic actuation logs or timestamps (varies by manufacturer and local deployment)

How clinicians typically interpret them (operationally)

In a hospital workflow, interpretation usually focuses on:

  • Confirming that a sufficient number of doses remain to complete the scheduled course or shift needs
  • Confirming the counter decremented as expected after actuations (noting that counters count actuations, not lung delivery)
  • Identifying devices approaching end-of-life so replacements can be issued without missed doses

Common pitfalls and limitations

Key limitations and misinterpretation risks include:

  • A dose counter reflects actuations, not confirmed inhalation or therapeutic deposition.
  • Not all Metered dose inhaler MDI products have a counter; โ€œcounting puffsโ€ requires reliable documentation discipline.
  • Priming actuations may reduce remaining doses; whether they decrement the counter and how they are represented varies by manufacturer.
  • โ€œShake and listenโ€ or โ€œfloat testsโ€ are not reliable universal methods for remaining-dose estimation and may contradict manufacturer guidance.
  • Visual plume strength can be misleading; an MDI may still spray even when not delivering labeled doses at the end-of-life threshold (exact behavior varies by manufacturer).

What if something goes wrong?

Because Metered dose inhaler MDI is small and familiar, failures are often handled informallyโ€”yet recurring minor issues can create major variability across units. A structured troubleshooting approach supports safer, more consistent care.

Troubleshooting checklist (practical)

If the inhaler does not perform as expected, consider:

  • Wrong product selected: re-check label, strength, and patient assignment.
  • Cap or packaging obstruction: confirm the cap is removed and the mouthpiece is unobstructed.
  • Canister not seated: remove and reinsert the canister firmly into the actuator.
  • Priming needed: verify whether priming is required due to first use, cleaning, dropping, or time since last use (varies by manufacturer).
  • Shaking needed: some products require shaking before each actuation; others may not (varies by manufacturer).
  • Empty or near-empty: check the dose counter; if no counter, consult the facilityโ€™s puff-tracking record.
  • Clogged actuator/mouthpiece: residue can block the nozzle; clean per IFU (do not wash the pressurized canister unless specifically allowed by the manufacturer).
  • Damaged actuator: cracks or deformation can alter plume direction; remove from service if damaged.
  • Dose counter not moving: treat as a reliability issue; follow policy for replacement and incident reporting.
  • Environmental extremes: very cold devices may spray differently; avoid unsafe warming methods and follow manufacturer storage guidance.

When to stop use immediately (general)

Stop using the Metered dose inhaler MDI and replace/escalate if:

  • The device is cracked, leaking, or visibly damaged
  • The medication identity, strength, or patient assignment is uncertain
  • The device appears contaminated (visible soil, exposure to bodily fluids) and policy does not allow reprocessing
  • The counter indicates no remaining doses, or facility tracking shows depletion
  • The patient experiences unexpected acute deterioration after administration; follow local emergency protocols and report per policy

When to escalate to biomedical engineering, pharmacy, or the manufacturer

Escalation routes vary by facility, but common patterns are:

  • Pharmacy: product selection issues, substitutions, shortages, recalls, lot tracking, formulary alternatives
  • Biomedical engineering/clinical engineering: accessory device governance (spacers/VHCs, masks, ventilator adapters), storage solutions, process improvement, failure trending
  • Manufacturer: suspected device defect, counter malfunction, valve/actuator issues, instructions clarification, product complaint handling
  • Risk management/regulatory reporting: repeated failures, potential harm events, or suspected counterfeit supply chains

A useful operational practice is to capture MDI-related issues in the same incident-learning system used for other clinical devices, even when the event seems โ€œminor.โ€

Infection control and cleaning of Metered dose inhaler MDI

Infection control for Metered dose inhaler MDI is often less about โ€œdeep sterilizationโ€ and more about clear assignment rules, high-touch cleaning discipline, and accessory management.

Cleaning principles (general)

Most facilities aim for:

  • Single-patient assignment of the Metered dose inhaler MDI whenever possible
  • Strict rules against sharing mouthpieces, actuators, spacers, or masks across patients unless a validated reprocessing protocol exists
  • Standardized handling for storage, transport, and bedside placement to reduce contamination

Some institutions use โ€œcommon canisterโ€ approaches in controlled settings, where the medication canister may be shared while patient-contact components are patient-specific. Whether this is appropriate is highly policy-dependent and must align with manufacturer guidance and infection prevention governance.

Disinfection vs. sterilization: practical distinctions

  • Cleaning: physical removal of residue and debris (often the most important step for performance and hygiene).
  • Disinfection: reduction of microbial load using chemical agents; level depends on policy and device material compatibility.
  • Sterilization: elimination of all microorganisms, typically requiring methods (heat, gas, radiation) that many MDI plastic components and pressurized canisters cannot tolerate.

In many workflows, the pressurized canister is not immersed or sterilized. Actuator washing and surface disinfection are more commonโ€”always per manufacturer IFU and facility-approved chemical compatibility lists.

High-touch points to focus on

For Metered dose inhaler MDI and accessories, typical high-touch/contamination-prone points include:

  • Mouthpiece opening and internal nozzle area
  • Outer actuator body where hands grip the device
  • Cap interior (can trap moisture and debris)
  • Spacer/VHC mouthpiece and valves
  • Mask rim and straps (if used)

Example cleaning workflow (non-brand-specific)

A generic approach (adapt to IFU and local policy):

  1. Perform hand hygiene and don appropriate PPE.
  2. Verify the device is assigned to the correct patient (or follow the facilityโ€™s shared-canister protocol if applicable).
  3. If cleaning the actuator, remove the canister from the plastic actuator (do not immerse the pressurized canister unless manufacturer guidance explicitly allows it).
  4. Clean the actuator using warm water and mild detergent if permitted, focusing on the nozzle area; rinse if instructed.
  5. Allow the actuator to air-dry completely before reassembly (residual moisture can affect spray characteristics; the extent varies by manufacturer and formulation).
  6. Wipe the exterior surfaces (cap, actuator body) with facility-approved disinfectant that is compatible with plastics.
  7. Reassemble the canister into the actuator only when dry, recap, and store per policy.
  8. Clean or replace the spacer/VHC and mask per their specific IFU and facility schedule; document as required.

Where hospitals struggle most is consistency: different units may โ€œcleanโ€ differently. Standard operating procedures, posted visuals, and periodic audits often provide better results than ad hoc reminders.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer): why it matters for Metered dose inhaler MDI

In Metered dose inhaler MDI supply chains, the โ€œmanufacturerโ€ on the label is often the entity responsible for the overall product, regulatory submissions, pharmacovigilance, and quality system oversight. An OEM may produce key components (valves, actuators, dose counters, canisters) or provide contract manufacturing services.

For procurement and operations leaders, OEM relationships matter because they can affect:

  • Quality consistency: component tolerances and assembly processes influence delivered dose performance
  • Change control: supplier changes (valves, plastics, propellants) can require regulatory filings and may affect training or accessory compatibility
  • Service and support: who provides training materials, complaint handling, and product traceability
  • Supply resilience: reliance on single-source components can increase shortage risk (details often not publicly stated)

A practical takeaway: even when Metered dose inhaler MDI is procured as a medication line item, the device component is still part of the safety and performance profile. Asking structured supplier questions is appropriate.

Procurement and reimbursement structures can influence brand availability and substitution practices for Metered dose inhaler MDI. Urban hospitals often have robust respiratory services and training resources compared with rural areas.

Germany

Germany is a mature European market with strong regulatory oversight, high expectations for quality and documentation, and established chronic disease pathways. Procurement decisions may increasingly consider sustainability policies and standardization across hospital groups, alongside clinical and economic factors. Access is generally strong nationwide, supported by well-developed distribution networks.

Thailand

Thailandโ€™s demand for Metered dose inhaler MDI is supported by universal coverage frameworks and expanding chronic disease management programs. Public procurement and hospital formularies strongly influence which products are widely available. Urbanโ€“rural disparities persist, making standardized education and supply planning important for consistent outcomes.

Key Takeaways and Practical Checklist for Metered dose inhaler MDI

  • Treat Metered dose inhaler MDI as a drugโ€“device system, not โ€œjust a medication canister.โ€
  • Standardize which Metered dose inhaler MDI products and spacer/VHC models are stocked to reduce training burden.
  • Build a unit-based checklist for MDI pre-use checks: label, expiry, integrity, counter, cleanliness, assignment.
  • Do not assume different canisters and actuators are interchangeable; compatibility varies by manufacturer.
  • Implement clear policy on single-patient assignment versus any shared-canister workflow, with infection prevention sign-off.
  • Make dose counter reading (if present) a routine โ€œstatus checkโ€ before administration and during handover.
  • For products without dose counters, enforce a reliable puff-tracking documentation method at the point of care.
  • Include priming instructions in training because priming needs and dose impact vary by manufacturer.
  • Include shaking instructions in training because formulation requirements vary by manufacturer.
  • Keep a defined process for replacing damaged actuators and disposing of pressurized canisters safely.
  • Use barcode scanning or equivalent verification to reduce look-alike/sound-alike inhaler selection errors.
  • Separate storage bins for high-risk look-alike inhalers and use tall-man lettering where your system permits.
  • Ensure staff know that a sprayed plume does not confirm lung delivery; technique still matters.
  • Make spacer/VHC availability predictable so staff do not improvise with incompatible accessories.
  • Treat spacer/VHC cleaning and replacement as an infection-control program, not an informal practice.
  • Avoid cleaning methods that immerse the pressurized canister unless explicitly permitted by the IFU.
  • Require actuator drying time per IFU to prevent moisture-related performance variability.
  • Document patient technique education at discharge and reinforce with teach-back whenever possible.
  • Build respiratory device competency into onboarding for nurses, interns, and rotating clinicians.
  • Trend MDI-related incidents (empty devices, counter failures, wrong selection) like any other clinical device issue.
  • Coordinate pharmacy, respiratory therapy, and biomedical engineering roles so ownership gaps do not occur.
  • Confirm local hazardous waste rules for disposal of pressurized containers and educate staff accordingly.
  • Include oxygen and fire safety reminders in MDI training for high-flow or oxygen-rich environments.
  • Establish a recall response plan that includes patient-specific MDIs already issued on wards.
  • Verify that procurement contracts specify what support is included: IFUs, training materials, complaint handling.
  • Ask suppliers how they manage change control for valves/actuators; details may be not publicly stated.
  • Prepare substitution playbooks for shortages so brand switches do not break technique competency.
  • Evaluate total operational cost, including staff time, education, and accessory consumptionโ€”not only unit price.
  • Use clear bedside labeling to prevent device mix-ups when multiple inhalers are prescribed.
  • Keep MDIs capped and stored cleanly to reduce mouthpiece contamination from lint and fluids.
  • Consider language accessibility of IFUs and patient leaflets as a procurement and equity requirement.
  • For ventilated use cases, only use adapters and workflows approved by policy and manufacturer guidance.
  • Audit adherence to cleaning and assignment rules in high-turnover units like ED and short-stay wards.
  • Maintain a minimum par level of compatible spacers/VHCs to avoid cross-patient sharing under pressure.
  • Ensure documentation distinguishes therapeutic actuations from priming actuations when relevant.
  • Train staff to recognize when to remove a device from service and escalate to pharmacy/manufacturer.
  • Integrate MDI technique checks into chronic disease clinics to reduce downstream admissions due to poor use.
  • Align infection-control policy with real workflow so staff are not incentivized to bypass safe practice.
  • Build supplier performance KPIs around fill rate, shortage communication, and recall execution quality.
