Flashcards in Vent Equations Deck (11):
1

Compliance Calculation

Vt/(Pplat-PEEP)

2

Resistance Calculation

R=(PIP-Pplat)/Flow

Flow is measured in L/sec

3

Minute Volume Calculation

MV=Rate x Tidal Volume

4

TCT with RR

Calculation

TCT=60/RR

5

Ti Calculation

Vt/Flow

Vt is measured in L

Flow is measured in L/sec

6

Te Calculation

Te=TCT-Ti

7

I:E Calculation

I:E=Ti/Ti:Te/Ti

8

FiO2 Required

Calculation

(PaO2 Desired * FiO2 Present) / PaO2 initial ABG

9

New PaCO2 Desired

Calculation

New PaCO2 Desired = Present PaCO2 – [ (pH Goal – pH Present) / 0.01}

10

MV required Calculation

MV required = (PaCO2 Initial * MV) / PaCO2 desired

11

PIP Calculation

(R X flow) + (Volume / compliance) + PEEP
