Condition requiring sedation to be administered 
Airway obstruction

Decompression illness

Question 2

Cautions

Answer 2

Morbidly Obese, neonate, COPD, CO2 retainer, on home oxygen, on home CPAP or BiPAP, administered in confined space.

Question 3

Complications

Question 4

Flow rates

Answer 4

Nasal prongs: 1-4
Simple: 6-8
Neb: 8
Reservoir: 10-15
MBM: 10-15

Question 5

Delivery device

Answer 5

Simplest one and at lowest FR possible to achieve SpO2 of 94-97%
NP/ SM: most pt
Severe hypoxia or carbon monoxide poisoning: reservoir
Peep/ assisting with RR: MBM

Question 6

COPD and oxygen

Answer 6

Titrate to pt normal oxygen salts
If not known between 88-92%
Use medical air as driver for nebuliser medication
If pt requires supplemental oxygen use nasal prongs
If medical not available use oxygen for driver with neb on for 5 and off for 5.
Monitor for signs of decreased respiratory drive and hypercarbia
