Aims of the teaching
Update and increase knowledge on different devices
Test baseline knowledge ( to improve at the end of the session!)
To become more familiar with delivery devices
Increase skills in assessment of technique How to trouble shoot

Metered dose inhalers (MDI)
Cheap, Quick & convenient to use Poor inhaler technique is common When used correctly only 10%-20% of the
drug reaches the lungs may continue to deliver propellant after
active drug gone if not shaken correctly important to wait 30-60 secs between doses
due to 2nd actuation being of poorer quality

Breathe actuated inhalers
Spring mechanism is triggered by inspiratory flow rate of 22-36 l/m
drug delivery less dependent on technique When cap is removed the inhaler is primed
and ready to fire

Spacer devices
Removes the need for co-ordination of breathing and actuation
Pharyngeal deposition is greatly reduced smaller particles penetrate further into lungs
depositing a greater proportion of drug Available with mask Electrostatic charge reduces delivery

Dry Powder inhalers (DPI)
Inspiratory airflow releases the fine powder - therefore no co-ordination needed
dose counters helps patients to know when empty (between 60-200 doses)
DPI can make some patients cough Inspiratory flow rate needed may be a
problem with some devices
![Page 10: Inhalers The Perfect technique Vicky Walker Clinical Lead for Respiratory Services Sarah Wilson Respiratory Nurse Specialist.](https://reader036.fdocuments.us/reader036/viewer/2022062511/5517e25f550346c6568b4586/html5/thumbnails/10.jpg)
Dry Powder inhalers (DPI) continued
More expensive than MDI’s DPI’s such as turbohalers have no
taste, hence there could be uncertainty it has been taken by the patient
Turbohalers delivers 20%-30% of drug Diskhaler delivers 11%-15% of drug
Ref:Optimizing deposition of aerosolizesd drug in the lung

Important points
Patient needs to be in a good upright position to use inhaler
Important to check inhaler technique regularly
Bad habits form quickly If a patient is requiring repeat
prescriptions – alarm bells should be ringing
