Ventilation Flashcards
1
Q
Peak flow/inspiratory flow
A
Speed at which gas travels to the patient during inspiration to achieve Vt - 60L/min
2
Q
End inspiration
A
The percentage of peak inspiratory flow at which the ventilator cycles from inspiration to expiration (ie if peak flow is 60L/min - EI will trigger at 15L/min - 25% normal setting )
3
Q
Inspiratory rise time
A
How quickly the ventilator achieves the clinician determined inspiratory pressure for mandatory and spontaneous breaths - 0.15s
4
Q
Trigger L/min
A
Flow trigger: how much flow is required to be taken away from the ventilator to notice effort of spontaneous breathing - 1.6L/min
5
Q
TpL
A
Plateau time : 0.0 normal
6
Q
SIMV VC
A
Variables are rate and tidal volume based on IBW which is ibw x 6-8
7
Q
SIMV PC
A
Variables are rate and PC depicts pts TV
