A/C (PCV) Flashcards
PCV-Increase in PEEP with no change in compliance
Increases
-PIP, Pplat
NO CHANGE
-Vt, flow, I-time, I:E
PCV-Increase in driving pressure (PS)
Increases
-VTinspired, Vtexpired, Insp. flow, PIP, Plat
NO CHANGE
-I-time, I:E
PCV-Increase in PEEP INCREASE in compliance
Increases
-VTinspired, VTexpired, PIP, Pplat
NO CHANGE
-Insp. flow, I:time, I:E
PCV-Increases in I-time, flow NOT reaching 0
Increases
-VTinspired, VTexpired, I-time, I:E
NO CHANGE
-Insp. flow, PIP
PCV-Increases in I-time with flow reaching 0
Increases
-I-time, I:E
NO CHANGE in anything else when flow reaches zero
PCV-Decrease in lung compliance
Decreases
-VTinspired, VTexpired
No change in anything else
PCV-Increased airway resistance (flow not reaching zero)
Decreases
-VTinspired, VTexpired, Insp. flow
NO CHANGE in I-time, PIP, or PLAT
PCV-Air trapping
Decreases
-VTinspired, VTexpired
No change in anything else, just decreases lung volume
PCV-Air leaks
Increases
-VTinspired, Insp. flow
No change or slight decrease in VTexp, if so, decrease in PLAT too.
PCV-Increased pt. effort
Increases
-VTinspired, VTexpired, Insp. flow
No change in anything else
PCV-Pt breaths above the set rate
Increases I:E ratio by decreasing expiratory time
PCV- RRT increases the rate on the machine
Will decrease VtExh. if flow not reaching zero, if so, PLAT will decrease too
No change if flow is still reaching zero
Will increase I:E ratio if I-time is set, no change if set I:E
Inspiratory pressure
The inspiratory pressure equals the change in pressure
The PIP = change in pressure + PEEP
PIP = Pressure limit
PCV
Trigger, Limit, Cycle
Trigger- patient (pressure flow), time, manual
Limit- Pressure
Cycle- Time
