Q

pMDI requires

A

dexterity and the ability to coordinate actuation with inhalation
where this is an issue, a spacer device can be used or an alternative inhaler device can be considered

Q

This inhaler type delivers a fiche number of medication doses per canister, and after thee doses have been used it, the inhaler will continue to actuate, expelling propellant gas but no API!

Q

patients on this type of inhaler may inadvertently use ‘empty’ inhalers and inhale only propellant gas once all the medicated doses have been used up which could lead to exacerbation and destabilisation of their condition

Q

MHRA advice: pMDI - risk of airway obstruction from aspiration of loose objects

A

reports of pt who have inhaled objects into back of throat, in some cases these were aspirated causing airway obstruction
remove mouthpiece cover fully, soak inhaler device and check that both outside and inside of mouthpiece are clear and undamaged before inhaling dose
always store inhaler with mouthpiece cover on

Q

advantages of using spacer device with pMDI

A
  • removes need for coordination between actuation of pMDI and inhalation
  • reduce velocity of aerosol and subsequent impaction on oropharynx, and allow more time for evaporation or propellant so that large proportion of particles can be inhaled and deposited into lungs
  • useful if poor inhalation technique, elderly, high dose ICS, prone to oral thrush with ICS

16
Q

techniques when inhaling from spacer device

A
  • One puff at a time either using the TIDAL (multiple) breathing method or SINGLE breath and hold method
  • do this until total dose (may be more than a single puff) has been administered
17
Q

True or false - when inhaling puffs from space device, tidal breathing is as effective as single breath method

A

true

18
Q

how often to clean spacer devices and how to clean

A

once a month
wash in mild detergent and allow to air dry
clean mouthpiece free from detergent before using

19
Q

why should you avoid cleaning spacer device more often than once a month

A

electrostatic charges can affect drug delivery

20
Q

how often to replace spacers

A

every 6-12 months

21
Q

spacer device - what is tidal breathing (aka multiple breathing) ? and when is it recommended over single breath and hold method?

A
  • usually recommended if you can’t hold breath for 5 seconds after using inhaler, or if you are having asthma attack
  • lips around mouthpiece to make a tight seal, then press canister on inhaler once to release the medicine, then breathe in and out SLOWLY and STEADILY into spacer five times
  • if prescribed a second puff, keep spacer away from mouth, wait a min, then shake inhaler again, then repeat the steps
22
Q

tidal breathing spacer technique - how do you actually breathe?

A

breathe in and out SLOWLY AND STEADILY into spacer 5 times once you have pressed the canister

23
Q

how to use pMDI inhaler with spacer using the single breath and hold method

A

breathe out gently and slowly until lungs feel empty and you are ready to breathe in
put lips around mouthpiece to make a tight seal, then press canister on inhaler once and breathe in slowly and steadily until lungs feel full
take mouthpiece of spacer out mouth and keep lips closed, and hold breath for up to 10 seconds or for as long as you comfortably can
then breathe out gently away from the spacer

24
Q

if a patient is having an asthma attack and they are using a spacer and pMDI, what method of breathing is recommended

A

tidal breathing (aka multiple breaths)

25
Q

name an example of a soft mist inhaler

A

Respimat

26
Q

how to use a soft mist inhaler

A

Breathe out gently and slowly away from the inhaler until your lungs feel empty and you feel ready to breathe in. Put your lips around the mouthpiece of the inhaler to make a tight seal without blocking the two holes on either side. Start to breathe in slowly and steadily, and at the same time, press the big grey button on the inhaler once. Continue to breathe in slowly until your lungs feel full. Take the inhaler out of your mouth and hold your breath for up to ten seconds, or for as long as you comfortably can. Then breathe out gently away from your inhaler. Wait for 30 seconds and repeat for a second puff

27
Q

How to use a pMDI (aka puffer)

A

Breathe out gently and slowly away from the inhaler until your lungs feel empty and you feel ready to breathe in. Put your lips around the mouthpiece of the inhaler to make a tight seal. Start to breathe in slowly and steadily and, at the same time, press the canister on the inhaler once. Continue to breathe in slowly until your lungs feel full. Take the inhaler out of your mouth and with your lips closed hold your breath for up to ten seconds or for as long as you comfortably can. Then breathe out gently away from your inhaler. If you’ve been prescribed a second puff wait 30 seconds to a minute and shake the inhaler again, then repeat the steps.

28
Q

Examples of a DPI

A

Accuhaler
Spiromax
NEXThaler
Ellipta
Turbohaler
Handihaler
Breezhaler
Easyhaler
Genuair
Zonda
Forspiro

29
Q

How to use DPI e.g. Accuhaler, Spiromax, NEXThaler, Ellipta, Turbohaler, Handihaler, Breezhaler, Easyhaler, Genuair, Zonda, Forspiro

A

Breathe out gently and slowly away from the inhaler, until your lungs feel empty and you feel ready to breathe in. Put your lips around the mouthpiece to make a tight seal. Breathe in quickly and deeply until your lungs feel full. Take the inhaler out of your mouth and hold your breath for up to ten seconds or for as long as you comfortably can. Then breathe out gently away from your inhaler. If you’ve been prescribed a second puff, slide the cover closed to reset the inhaler and repeat the steps. When you’ve finished, close the cover.

30
Q

DPI require you to breathe in …

A

quickly and deeply until your lungs feel full

31
Q

How to use breath-actuated inhaler e.g. Easi-Breathe, Autohaler

A

Breathe out gently and slowly away from the inhaler until your lungs feel empty and you feel ready to breathe in. Put your lips around the mouthpiece of the inhaler to make a tight seal. Breathe in slowly and steadily. Continue to breathe in when you feel the inhaler puff in your mouth until you have taken a full deep breath in. Take the inhaler out of your mouth and hold your breath for up to ten seconds or for as long as you comfortably can, then breathe out gently away from the inhaler.
