1
New cards

exponential pressure waveform

VC

2
New cards

square pressure waveform

PC

3
New cards

constant flow waveform

VC

4
New cards

decelerating flow waveform

PC (always) or VC

5
New cards

sinusoidal flow waveform

spontaneous

6
New cards

PV loop compliance decreases PC-CMV

loop is shorter (less volume delivered)

7
New cards

PV loop widens/bulges

increased airway resistance

8
New cards

spontaneous P-V loop

clockwise

9
New cards

patient-triggered mandatory P-V loop

counterclockwise after initial negative deflection

10
New cards

F-T does not return to zero

air trapping/ auto-PEEP

11
New cards

F-V loop expiratory side ends above zero volume

leak in patient circuit (bronchopleural fistula)

12
New cards

Gap at the zero intercept on a flow volume loop

air trapping or intrinsic PEEP

13
New cards

scooped-out flow-volume loop appearance

increased airway resistance (bronchospasm)

14
New cards

Auto-PEEP reduction

increasing flow, reducing VT, reducing rate, suctioning, changing mode for more spontaneous breahts

15
New cards

Initial adult patient triggering

1-2 cmH2O
