Question 1

What is a trigger

Answer 1

Mechanism that is used by the ventilator to start inspiration

Question 2

What is a limit

Answer 2

Parameter that can be reached and maintained at a present level before inspiration ends
Does not terminate inspiration

Question 3

Cycle

Answer 3

The inspiratory phase will end once a certain variable reaches a present value

Question 4

Baseline

Answer 4

Will always be PEEP

Question 5

How is tidal volume determined in VC-CMV

Answer 5

Set by you

Question 6

How is tidal volume determined in PC-CMV

Answer 6

Based upon pressure and compliance

Question 7

How is tidal volume determined in PC-CMV adaptive

Answer 7

Based up the set volume (not flow)

Question 8

Baseline-Peep

Question 9

PC-CMV trigger, limit, cycle, and baseline

Answer 9

Question 10

PC-CMV Adaptive trigger, limit, cycle, and baseline

Answer 10

Trigger-Time or patient
Limit-Pressure
Cycle-Time
Baseline-Peep

Question 11

Purpose of ramp or inspiratory rise time

Answer 11

The use of a ramp is to match the way we naturally breathe. Normally, a person intakes more air in at the start of their inspiration, then less as the breath goes on until expiration happens. (DIctates how fast the pressure reaches peak)
