Vent Equations Flashcards
1
Q
Compliance Calculation
A
Vt/(Pplat-PEEP)
2
Q
Resistance Calculation
A
R=(PIP-Pplat)/Flow
Flow is measured in L/sec
3
Q
Minute Volume Calculation
A
MV=Rate x Tidal Volume
4
Q
TCT with RR
Calculation
A
TCT=60/RR
5
Q
Ti Calculation
A
Vt/Flow
Vt is measured in L
Flow is measured in L/sec
6
Q
Te Calculation
A
Te=TCT-Ti
7
Q
I:E Calculation
A
I:E=Ti/Ti:Te/Ti
8
Q
FiO2 Required
Calculation
A
(PaO2 Desired * FiO2 Present) / PaO2 initial ABG
9
Q
New PaCO2 Desired
Calculation
A
New PaCO2 Desired = Present PaCO2 – [ (pH Goal – pH Present) / 0.01}
10
Q
MV required Calculation
A
MV required = (PaCO2 Initial * MV) / PaCO2 desired
11
Q
PIP Calculation
A
(R X flow) + (Volume / compliance) + PEEP
