Question 1

Incentive spirometry

Answer 1

A hand-held device that exercises your lungs and measures how much air you can breathe in.

It tells you and your doctor how well your lungs are working.

The spirometer can help you practice taking deep breaths.

Question 2

How are Air Entrainments devices (venturi devices) related to the Bernoulli principle?

Answer 2

Gas is delivered from a device through a device but theres air entrainment device that draws in EXTERNAL ROOM air increasing total flow

Question 3

How are Air Entrainments devices (venturi devices) related to the Bernoulli principle?

Answer 3

Gas is delivered from a device through a device but there’s air entrainment device that draws in EXTERNAL ROOM air increasing total flow

Question 4

Positive airway devices: how do you increase pressure?

Answer 4

Increase flow = Increase pressure

Question 5

Normal values for PEF for men?

Answer 5

In men, readings up to 100 L/min lower than predicted are within normal limits

Question 6

Normal values for PEF for women?

Answer 6

For women, the equivalent figure is 85 L/min lower than predicted.
