Ch.3 Administration Of Aerosolized Agents Flashcards
What are the 3 main uses of aerosol therapy
Humidify dry inspired gases
Improve clearance of resp secretions
Deliver aerosolized drugs to resp tract
DPI ( Dry powdered inhaler)
Inability to generate adequate inspiratory flow is considered a significant limitation.
If a patient cannot produce the sufficient flow rate, an alternative should be considered
- Inspiratory flow rate
- humidity
- clinical efficiency
What should be used to improve deposition of medication delivery and to prevent impaction in back of throat
MDI reservoir devices ( anti static chambers and spacers)
What is the only corticosteroid that can be administered via SVN
Pulmicort
If a patient prefers Spiriva they can only receive it via ___
DPI and Respimat
Jet ( pneumatic) nebulizer with reservoir tube
Corrugated tubing on exhaust side of the device acts as the reservoir
Respirgard ll
Variation of SVN fitted with one way valves and generate effective particle size of Antiinfective agent “pentamidine”
Aerosol Therapy
refers to delivery of aerosol particles to the respiratory tract
What are the 3 mechanisms of deposition
- Inertial impaction
- Gravitational settling
- Diffusion
What are the types of nebulizers
Jet neb
Mesh neb
Ultrasonic neb
Respirgard ll
What device can be used for continuous delivery
HEART or HOPE( large reservoir nebulizer)
- can deliver does of 10-15 mg/hr
SPAG
Small particle aerosol generator( SPAG)
SPAG is used to administer RIBAVIRIN
Types of jet nebs
Jet neb with reservoir tube
Jet neb with collection bag
Breath enhanced jet neb
Breath actuated jet neb
Advantages of SVN ( small volume neb)
Aerosolize many solutions
Can aerosolize more that one drug
Minimal cooperation
3 types of Pmdi
Conventional
Breath actuated
Respimat
