airway resistance Flashcards
1
Q
what is the equation for flow (airway resistance)
A
Flow = deltaP/R
2
Q
what does delta P stand for (airway resistance)
A
pressure gradient
3
Q
what does R stand for (airway resistance)
A
resistance
4
Q
what is resistance mostly determined by
A
the diameter of the airway
5
Q
which airways mostly have a high diameter
A
initial conducting airways
6
Q
why do initial conducting airways have a very high diameter
A
Diameter size is relative to the low viscosity of air
7
Q
why do bronchioles have low resistance
A
because they have a huge cross-sectional area
8
Q
what are the main resistance passageways
A
the medium-sized bronchi
