Q

Explain how to use a turbuhaler.

A
  1. unscrew cap and take it off, hold the inhaler upright

  4. put mouthpiece between teeth, close lips and breathe in forcefully+deep
  5. remove from mouth before breathing out
  6. always check the dose counter or for a red mark (indicates empty)

Q

What is a diskus? Describe it.

A

breath activated device
can feel the drug
maintain parallel to ground once activated
has a dose counter

22
Q

True or false: a diskus has a relatively long expiry date

A

false
typically have shorter expiry dates

23
Q

Does drug delivery vary with different ranges of air flow rates for a diskus?

A

fairly consistent across a range of drug delivery rates

24
Q

Explain how to use a diskus.

A
  1. open diskus, hold in palm, put thumb of other hand on the thumb grip and push the thumb grip until it clicks into place
  2. slide the lever away from you as far as it will go to get your med ready
  3. breathe out away from the device
  4. place mouthpiece in mouth and close lips
  5. breathe in deeply until you have taken a full breath
  6. remove the diskus from your mouth
  7. hold breath for 10s and then breathe out
  8. check the number of doses
25
What is a handihaler? Describe it.
breath activated device uses capsules (light+moisture sensitive) technique requires multistep process
26
Do handihalers have a dose counter?
no 1 capsule=1 dose (thus no dose counter)
27
True or false: if you wanted to clean a handihaler, it would be appropriate to use detergent or cleaning agents
false
28
Does drug delivery vary with different ranges of air flow rates for a handihaler?
drug delivery consistent across range of air flow rates
29
Describe how to use a handihaler.
1. remove capsule from package (dont take it out any sooner than needed) 2. flip off the lid of the handihaler 3. flip open the mouthpiece 4. put the capsule in the hole 5. flip the mouthpiece closed, make sure you hear a click 6. hold the handihaler upright, with the mouthpiece facing up 7. sit up with your back straight 8. press the button on the side (pokes hole in capsule) 9. exhale all of your air 10. seal lips around the mouthpiece 11. breathe in slowly and deeply until lungs are full 12. as you breathe in you should notice the handihaler is vibrating (shows its taken properly) 13. take handihaler out of mouth and hold breath for as long as you can 14. breathe out normally 15. take another breath from handihaler (ensuring you take all the med) 16. take handihaler out of mouth 17. hold breath for as long as you can 18. breathe out normally 19. discard capsule
30
Which devices are similar to the handihaler?
breezhaler aerolizer
31
What are the common errors for dry powder inhalers?
not keeping the device in correct position while loading dose not keeping device in correct position when inhaling failing to exhale fully before use failing to inhale completely inhaling too slowly or weakly using past expiry date or when empty
31
What are the newer devices that are pre-loaded, offering more choice and convenience for patients?
ellipta and genuair
32
Describe the Ellipta.
simply open cap to prepare dose make sure the air intake vent is not covered during inhalation short expiration date after removing protective coating
33
Describe the Genuair.
simply press down loading button to prepare dose the loading button will lock to signal empty make sure the button is completely released prior to inhalation
34
What must be immediately discarded after opening the Ellipta?
desiccant and foil packaging
35
What must be done before inhaling a dose from an Ellipta?
open the colored cap, there is a "click" when the dose is ready to be inhaled
36
How can a dose of an Ellipta be lost?
opening and closing the cover without inhalation of the loaded dose
37
When will the Ellipta dose counter turn red?
when there is less than 10 doses remaining
38
How should an Ellipta be held?
just below horizontal -if the device is tipped past horizontal, the medication will fall out of the mouthpiece
39
How do you prepare a Genuair for inhalation?
coloured button should be pressed and released -coloured control window will change from red to green -do not hold down the button while inhaling during dose inhalation there is an audible "click" -after proper inhalation the window will change back to red -keep breathing in even after the click to ensure delivery of full dose
40
When should someone on a Genuair obtain a new inhaler?
when a red striped band appears in the dose window
41
What are the pros of SMI respimats?
slow moving mist gives pt time to inhale no effort needed to coordinate improved delivery to lungs dose indicator
42
What are the cons of SMI respimats?
requires reasonable strength to spring load dose not approved for kids <5 or with spacer priming if unused for 3d (Combivent) or 7d (Spiriva/Inspiolto)
43
Explain how to use a Respimat.
1. prime inhaler (according to package) 2. turn clear base 1/2 turn (counter-clockwise) 3. open the cap until it snaps open 4. breathe out slowly and close lips around the mouthpiece without covering air vents 5. while taking in a slow deep breath, press the dose release button and continue to breath for as long as possible, hold breath for 10s 6. breathe normally 7. replace cap 8. if another dose is needed, rpt steps 3-8
44
What are the common errors with Respimat?
too deep of a breath may cause irritation at back of throat and coughing not pressing down on button while breathing not loading the canister into the device properly
45
What are the 5 steps to help remember a general inhaler technique?
1. prepare the dose 2. breathe out 3. breathe medication in 4. hold breath x 10 seconds 5. breathe out *may take 2nd breath from DPI to ensure entire dose is inhaled* *best to wait ~minute between puffs*
46
Which devices require priming?
MDI Respimat
47
Compare and contrast MDI vs SMI vs DPI.
MDI and SMI require coordination of timing of inhalation with activation of delivery DPI are breath actuated, timing of inhalation is not an issue and some are pre-loaded
48
What are nebulizers?
electric or battery powered machines that turn liquid medication into a fine mist that is inhaled user breathes in through a mouthpiece or mask
49
What are some factors to consider when choosing the right device for a patient?
ability of pt to coordinate ability to reach peak inspiratory flow physical limitations poor medication delivery during acute attacks advanced disease does the pt feel the med is working?
50
Which device is an important contributor to greenhouse emissions?
pMDIs -propellant=0.03% of emissions -if all other factors are equal, consider a DPI or SMI
51
What is the #1 reason for therapy failure of respiratory medications?
inhaler technique
