Spirometry

Question 1

Function of spirometer

Answer 1

Used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath

Question 2

What do results show?

Answer 2

1. If lungs aren’t working properly
2. If lungs are obstructive ( ability to breathe out quickly is affected by narrowing of airways, but the amount of air you can hold in your lungs is normal) or restrictive ( amount of air you can breathe in is reduced because your lungs are unable to fully expand)

Question 3

Precautions

Answer 3

• Functioning soda lime
• No air leaks- invalid results
• sterile mouthpiece
• Water chamber must not be overfilled ( water may enter into the air tubes)

Question 4

Why does the volume in the chamber slowly decrease?

Answer 4

The oxygen is used in respiration and, carbon dioxide is released in respiration, but the carbon dioxide is then absorbed by the sodalime causing a drop in volume

Question 5

Function of soda lime

Answer 5

Absorb CO2 being released during respiration

Question 6

Function of counterpoise

Answer 6

Allows chamber to move up and down
