Hemodynamic
Monitoring
Preload Amount of blood returning to the right side of the heart
Pressure against which the left ventricle must
Afterload
pump to eject blood
Compliance How easily the heart muscle expands when filled with blood
Contractility Strength of contraction of the heart muscle
Volume of blood pumped out of the ventricles
Stroke Volume (SV)
with each contraction
Amount of blood heart pumps through the
Cardiac Output (CO) have an inverse
circulatory system in one minute relationship
CO = HR x SV
↑ Compliance ↑ CO ↓ Compliance ↓ CO
↑ Contractility ↑ CO ↓ Contractility ↓ CO
↑ Stroke Volume ↑ CO ↓ Stroke Volume ↓ CO
