Hemodynamic monitoring is a central component of intensive care. Patterns of hemodynamic variables often suggest cardiogenic, hypovolemic, obstructive, or distributive (septic) etiologies to cardiovascular insufficiency, thus defining the specific treatments required.
Hemodynamic Medications Generally, cardiac medications targeting hemodynamic properties are designed to affect afterload (vascular resistance), preload (circulating blood volume), or contractility (inotropic property). [It should be emphasized that many of

Humans have a closed cardiovascular system, meaning that the blood never leaves the network of arteries, veins, and capillaries. Blood is circulated through blood vessels by the pumping action of the heart, pumped from the left ventricle through arteries to peripheral
Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of contraction. Afterload is the ‘load’ to which the heart must pump against. Afterload goes down when aortic pressure and systemic

Frank-Starling law: Within physiological limits, the force of contraction is proportional to initial length of cardiac muscle fibre (end diastolic fibre length) i.e. beyond the limit of stretch-ability of myocytes, instead of increase in contractility – the contractility diminishes.
