Flashcards in Resistance and Compliance concepts Deck (11):
1

Resistance varies with what in regards to an ETT?

volume of gas passing through the tube per unit time

2

what is importance in determing resistance?

flow (V)

3

The ETT causes an increase work in breathing due to ?

small diameter and length

4

what law is associated with resistance and gas flow?

hagen-poiseuille

5

what is formula associated with laminar flow resistance?

P = (L x v x V) / r^4

6

True or false. In Laminar flow, Resistance indirectly proportional to flow rate

false. directly proportional

7

true or false. In turbulent flow, Resistance directly proportional to square of flow rate

true

8

what formula is associated with turbulent flow resistance

P = (L x V^2 x K)/ r^5

9

What is the measure of distensibility?

compliance

10

what is the formula for compliance?

C = V/P units are ml/cmH2O

11

what are properties of compliance?

Helps determine tidal volume
Most distensible components are reservoir bag & breathing tubes
