hemodynamics Flashcards
(19 cards)
PAWP norm
5 - 12
mmHg
afterload equation
SVR= [(MAP - RAP)/CO] x 80
SVR norm
800 - 1200
DO2 equation
CI x hgb x 1.34 x SaO2 x 10
SaO2 = decimal %age
VO2 equation
CI x hgb x 1.34 x (SaO2-SVO2) x 10
equation to determine how much your toes ate and norm
VO2 / DO2
~25%
pulmonary systolic norm
20 - 30
mmHg
pulmonary diastolic norm
5 - 10
mmHg
CO norm
4 - 6
L/min
CI norm
2.2 / 4.0
L/min/m^2
SVO2 norm
60 = 80% higher = priority cells not being fed
CVP norm
2 - 4 mmHg
CVP is RAP
MAP norm
70 - 100 mmHg
PAC assumptions
no mitral valve disease
no excessive PEEP (false high)
no pulmonary hypertension
hemodynamics: monitor for critically ill patients
CI (CO), PAWP, hgb, SaO2, SVO2
critically ill patient hemodynamics - question to consider
are CO, hgb, and SaO2 sufficient to meet body demands?
what can you do to improve CI?
inotrope
preload
check SVR
how do you change hgb level?
blood transfusion (consider risk v benefits!!)
MAP
(SBP + 2DBP)/3
