Ventilation--Trachte Flashcards
1
Q

A
Tidal volume
about 500 ml
2
Q
Total lung volume is usually about?
A
4000 mL
3
Q
Total lung capacity is about?
A
7000 mL
4
Q
Maximum volume of air that can be expired after maximum inspiration?
A
Vital capacity
about 6000 mL
5
Q

A
residual volume
6
Q
Great chart on page….
A
5 in lecture PPT
7
Q
How to calculate alveolar ventilation?
A
volume of CO2 in exhaled air divided by fraction conc of CO2 in expired air (PCO2?)
PCO2 is inversely proportional to alveolar ventilation
ie: breath faster –> PCO2 goes down?
