Blood pressure (BP)
Pressure in blood vessels at systole and diastole.
Mean arterial pressure (MAP)
Average pressure over 1 cardiac cycle. Is a good estimation of perfusion to organs.
Pulse pressure (PP)
Difference between systolic and diastolic pressure.
Cardiac output (CO)
The amount of blood pumped by the left ventricle in 1 minute (measured in Liters).
Cardiac index (CI)
Cardiac output divided by body surface area.
Stroke volume (SV)
The amount of blood ejected with each ventricular contraction.
Systemic vascular resistance (SVR)
The amount of pressure the left ventricle has to push against to eject blood to the body during systole.
Pulmonary vascular resistance (PVR)
The amount of pressure the right ventricle has to push against to eject blood to the lungs during systole.
Central venous pressure (CVP)
Same as RAP. Measurement of right atrial pressure, which directly corresponds with fluid status. Normal is 2-6 mmHg.
Right ventricular pressure (RVP)
Pressure in right ventricle during systole and diastole. Normal is 15-25/0-8 mmHg.
Pulmonary artery pressure (PAP)
Pressures in pulmonary artery during systole and diastole. Normal is 15-25/8-15(10-20) mmHg.
Pulmonary occlusion pressure (PAOP) or "wedge" pressure
Pressure in the pulmonary artery during diastole, which directly corresponds with LVEDP (estimate of left ventricular preload). Normal is 4-12 mmHg.
