The up and down fluctuation of the arterial pressure results from the pulsatile nature of the cardiac output, i.e. the heartbeat. The pulse pressure is
Cardiac index (CI) is a vasodynamic parameter that relates the cardiac output (CO) to body surface area (BSA), thus relating
In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from one ventricle of the heart with each beat. SV is calculated using
Preload is described as the stretching of a single cardiac myocyte immediately prior to contraction and is, therefore, related to the sarcomere length.
The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion
Ejection fraction (EF) is the fraction of blood in the left and right ventricles pumped out with each heartbeat. EF is applied to both the right
In 1957 John Philip introduced the term sorptivity and defined it as a measure of the capacity of the medium to absorb or desorb liquid by capillarity.
Engine displacement is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead centre (... more
Mean arterial pressure
The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined from measurements of the systolic pressure
