Inhalation Therapy

Question 1

Nebulisers

Answer 1

-for inhalation of drugs in a more simpler way
-used also if drugs cannot be administered in other ways
-it converts solution into aerosol particles that are suspended in a gas stream
-duration=10-15 mins
- volume of drug delivered= 4ml
-drugs like mucolytics, bronchodilators, corticosteroids and antibiotics can be administered

Question 2

Types of nebulisers

Answer 2

-Jet nebulisers
-Ultrasonic nebulisers

Question 3

Jet nebulisers

Answer 3

-oxygen is forced through a narrow pipe in the middle of the nebuliser
-the negative pressure draws drug solution up the feed tube from the liquid container
-the jet of gas fragments turns liquid into droplets that leave the nebuliser in a stream of gas
-driving gas flow= 5-6 l/min
-meds are delivered using oxygen flow meter or a compressor (portable)

Question 4

Ultrasonic nebulisers

Answer 4

-aerosol created by high frequency sound waves
-electric current is applied to piezo-electrical crystal at the base of machine that causes ultrasonic vibrations
-frequency of oscillation of crystals influence the particle size of gas from liquid
-produces higher gas output than jet nebulisers

Question 5

Domiciliary nebulisers

Answer 5

• nebulisers that the pt is required to use at home
  -must be washed and dried thoroughly after each use to prevent bacterial growth
  -should be serviced as per the manufacturer
  -if travelling overseas, an nternational adaptor should be purchased
