Lecture 6 - Dynamics of Ventilation Flashcards
1
Q
For ventilation to occur, pressure must exceed?
A
tissue elastance, air-flow resistance
2
Q
Work of resistance?
A
proportional to frequency, COPD patients decrease f to decrease work
3
Q
Work of elastance?
A
proportional to tidal volume, lung stiffness patients decrease tidal volume to decrease work
