Hemodynamics Flashcards
Left Ventricle (LV)
120/0 mmHg
Systemic Arteries (MAP)
120/80 mmHg
Mean Arterial Pressure (MAP)
93 mmHg
Where arterioles enter the capillaries?
30 mmHg
Systemic Capillaries
20 mmHg
Systemic Veins (CVP)
2-6 mmHg
Or
4-12 cmH20
Right Arterial Pressure (RAP)
2-6 mmHg
Or
4-12 cmH20
Right Ventricle (RV)
25/0 mmHg
Pulmonary Artery (PAP)
25/8 mmHg
Pulmonary Artery (PAP) [Mean]
13-14 mmHg
Pulmonary Capillaries
8-10 mmHg
Pulmonary Capillary Wedge Pressure (PCWP)
4-12 mmHg
Left Atria (LA)
2-6 mmHg
Cardiac Output (QT)
4-8 L/min
How do you calculate Cardiac Output (QT) [2 equations]
QT = HR x SV
Or
Qt= VO2/(C(a-v)(O2x10)
Cardiac Index (CI)
2.5-4.0 L/min/m2
How do you calculate Cardiac Index (CI)?
CI = QT/BSA
Pulse Pressure (PP)
40 mmHg
How do you calculate Pulse Pressure (PP)?
PP= Systolic-Diastolic
Systemic Vascular Resistance (SVR)
<20 mmHg/L/min
Or
1600 dynes/sec/cm5
How do you calculate Systemic Vascular Resistance (SVR)?
SVR = (MAP-CVP) / QT
Pulmonary Vascular Resistance (PVR)
<2.5 mmHg/L/min
Or
200 dynes/sec/cm5
How do you calculate Pulmonary Vascular Resistance (PVR)?
PVR = (MPAP - PCWP) / QT
How do you convert:
mmHg/L/min
to
dynes/sec/cm5
Multiply mmHg by 80
Stroke Volume (SV)
60-130 mL/beat
How do you calculate Stroke Volume (SV)?
SV = QT/HR
Stroke Volume Index (SVI)
30-50 mL/beat/m2
Ejection Fraction (EF)
65-75%
