Mechanics of Breathing Flashcards
1
Q
What is the Law of Laplace?
A
P = 2T/r
P = collapsing pressure on alveolus T = surface tension r = radius of alveolus
2
Q
What is the equation for airflow in the respiratory system?
A
Q = P/R
Q = Air flow P = pressure difference R = resistance of the airway
3
Q
What is Poiseuille’s Law?
A
R = (8nl)/(3.14)r^4
R = resistance n = viscosity of inspired air r = radius of airway l = length of airway
