NIF <-20 cmH2O

Question 35

Number 1 contraindication

Answer 35

Untreated pneumothorax

Question 36

What is it when the tidal volume is set, and the pressure is variable

Answer 36

Volume control

Question 37

What is it when PIP is set, and the volume is variable

Answer 37

Pressure control

Question 38

Review wave forms

Answer 38

Know if it’s a pressure or volume mode
Pressure = squared first one

Question 39

Calculate I:E ratio

Answer 39

60 / Respiratory Rate (RR) = Total Cycle Time (TCT)
I + E = Ratio Time (RT)
TCT x [1ratio / RT] = Inspiratory Time (I-time)
TCT – Itime = Expiratory Time
