the volume of a breath that does not participate in gas exchange

27
Q

Define V.O2

Define IC

A

Inspiratory Capacity:

The volume of air that can be inspired following a normal, quiet expiration

35

A

Minute Ventilation: 6L/min

Volume of air expired each minute

38
Q

Define VD

A

Deadspace Volume: 150ml

Volume of air in the respiratory system where no gas exchange is taing place and therefore this is wasted air.

42
Q

Define FER

A

Forced Expiratory Ratio: FEV1:FVC
The ratio between the volume of forced air exhaled in the first second of expiration compared to the total capacity of the individual. Used to measure airway resistance
