1
Q
Define lung compliance
A
A measure of the ease at which our lungs can stretch
2
Q
What is the equation for lung compliance?
A
Change in lung volume/change in transpulmomary pressure
3
Q
Define elastic recoil
A
Lungs ability to return to its resting volume after distension
4
Q
What is the equation for resistance?
A
Pressure difference/flow (L)
5
Q
Define Poiseuilles Law
A
The pressure difference is directly proportional to the flow x resistance
