Inhalers Flashcards
Uses a power source to generate an aerosol from liquid medications
Nebulizer
Usually L shaped
Pressurized Metered Dose Inhaler (PMDI)
Usually tube/disc-shaped
Dry Powder Inhaler (DPI)
Usually tube/cylinder-shaped
Soft Mist Inhaler (SMI)
Typically contain a mouthpiece/mask, medication cup, tubing that connects cup and compressor
Nebulizer
Uses a propellant, actuated by pressing down on the canister to release an aerosol
PMDI
Does not use a propellant, twisting the base compresses a spring which transfers the medications to a dosing chamber
SMI
Inhalation disaggregates the powder into fine particles
DPI
Typically require a long, slow inhalation
PMDI and SMI
Requires a short, fast, forceful inhalation
DPI
Respimat is a
SMI
If a drug has HFA after its name it is a
PMDI
Discus and Ellipta are examples of
DPIs
Spacers decrease the need to
Time the actuation w/ inhalation
Nebulized meds are given over
10-15 minutes
What are the benefits of taking a combined inhaled medication?
Convenience
Cheaper
Prevents taking LABA alone for asthma
More effective
Peak Inspiratory Flow Meters can be used to?
Determine if DPIs are appropriate
Assess inhaler technique if inhaler is not available
