Pressures during the cardiac cycle in the chambers of the heart, the pulmonary artery & aorta

RIGHT ATRIUM

: 0 — 7 mmHg (higher in ventilated patients)

PULMONARY ARTERY

PA Systolic: 20 — 30 mmHg (same as LV systolic)

PA Diastolic: 6 — 10 mmHg

: < 20 mmHg

RIGHT VENTRICLE

RV Systolic: 20 — 30 mmHg

RVEDP: 0 — 7 mmHg (approx equal to )

PAWP

: 4— 12 mmHg (higher in ventilated patients)

LEFT ATRIUM

: 4— 12 mmHg (similar to )

LEFT VENTRICLE

LV Systolic: 100 — 140 mmHg

LVEDP: 4— 12 mmHg (similar to ; )

AORTIC PRESSURES

SystolicBP: 100 — 140 mmHg

[dependent on DBP & Pulse Pressure]

DiastolicBP: 60 — 80 mmHg

[dependent on Systemic vascularresistance]

Pulse Pressure: 40 — 60 mmHg

[determined by Stroke volume; elasticity of aorta; viscosity blood)

: 70 — 90 mmHg

= = DBP + PP

= CO x SVR
