Equations Flashcards
1
Q
Oxygen delivery to tissue
A
DO2 = CO x CaO2
2
Q
Cardiac output
A
CO = SV X HR
3
Q
Arterial oxygen content
A
CaO2 = (Hb x 1.36 x SaO2) + (PaO2 x 0.003)
4
Q
Oxygen extraction ratio
A
O2ER = VO2 / DO2
5
Q
Cardiac index
A
CI = CO / Body surface area
6
Q
Coronary perfusion pressure
A
CPP = DAP - RADP
7
Q
Shock index
A
Shock index = HR/systolic BP
8
Q
Blood pressure
A
BP = SVR x CO
9
Q
Oxygen extraction ratio
A
O2ER = VO2/DO2
10
Q
Mean arterial pressure
A
MAP = diastolic +(systolic-diastolic/3)
11
Q
Pulse pressure variation
A
PPV(%) = 100 x (PPmax - PPmin)/([PPmax+PPmin]/2)
