3 Breath characteristics of the 5 mech vent modes |
Trigger Target / Limit Cycle |
|
|
5 basic mech vent breaths / modes |
VC VA PC PA PS |
|
|
Name of the mode (volume / pressure) pertains to what? |
Pertains to the target or limit Therefore, VC = volume limited; PC = pressure limited |
|
|
What triggers the 5 basic mech vent modes? |
"Control" mode means time-triggered, other modes triggered by patient effort |
|
|
Differentiate the 5 mech vent modes? |
VC and VA are both volume limited and volume cycled, but VC is time triggered, VA is patient triggered
PC and PA are both pressure limited and time-cycled, but PC is time triggered and PA is patient triggered
PS is pressure targeted, flow- cycled, triggered by patient effort |
