pressure exerted by fluid in the right atrium?

Central Venous Pressure (CVP): indicative of right-sided heart function

fluid overload, cardiogenic and obstructive shock

decreased fluid in dehydration-hypovolemic shock; distributive and anaphylactic shock

increased in conditions with increased fluid in PA and decrease elasticity of PA?

PAP elevated: Hypervolemia or PAH

decreased amount of fluid-hypovolemia

measure of pressure in left ventricle at end-diastole (maximal stretch) (LVEDP)?

Pulmonary capillary wedge pressure (PCWP) or pulmonary artery occlusion pressure (PAOP): indicative of left-sided heart function

normal PCWP/PAOP?

elevated PCWP/PAOP in conditions?

increase pressure in left ventricle at end diastole: increased fluid, decreased elasticity of ventricle
Cardiogenic shock: MI, pulmonary edema, valve regurg

Decreased PCWP/PAOP in conditions?

decrease pressure in left ventricle at end diastole: Hypovolemia

amount of fluid in liters per minute that heart pumps into systemic circulation?

Cardiac Output (CO)

HR X SV = 4-8L/min

inotropic agents, excess fluid

drugs that decrease contractility, hypovolemia
