Cardiac PRESSURE-VOLUME LOOPS

Dr.Syed Shaheer Haider PGT Anesthesiology

Recalling…

Determinants of Cardiac Output:1. Preload2. Afterload3. Contractility (Inotropy)

Recalling…Preload: It is the presystolic stretch.Frank-Starling law states that greater

the preload, the greater will be cardiac output.

End-Diastolic volume is reflected in End-Diastolic pressure LVEDP=LA pressure.

Pulmonary artery wedge pressure(PCWP) = LA pressure = PA diastolic pressure

Recalling…

Afterload: Pressure that needs to overcome for left ventricle (Systole)

Defined as wall stress during systole

Laplace formula: Wall Stress ð = Pressure x Radius/2h ( Thickness)

Systolic pressure is often used to denote afterload

Recalling…

Contractility: That determines the strength of contraction

LVEF = Stroke volume End Diastolic volume

(or)

LVEF = End Diastolic volume – End Systolic volume

End Diastolic Volume
