Hemodynamic Terminology

13 cards·by kayhudson

CI (Cardiac Index)

Amount of blood pumped by the heart/L/min/m^2 BSA

SV (Stroke Volume)

Amount of blood pumped by the heart/cardiac cycle ml/beat

CO (Cardiac Output)

Volume of blood pumped by heart L/min

CVP (Central Venous Pressure)

Used to approximate RVEDP

RVEDP (Right Ventricular End Diastolic Pressure)

Asseses right ventricular function and fluid status

SVR (Systemic Vascular Resistance)

Measurement of the resistance of the systemic vascular bed to the blood flow

MAP (Mean Arterial Pressure)

Reflects changes in the relationsip between CO and SVR

SVO^2 (Saturated Venous Oxygenation)

Indicates adequacy of tissue oxygenation

PAP (Pulmonary Artery Pressure)

Blood pressure in the pulmonary artery

PWCP/PWAP (Pulmonary Capillary Wedge Pressure)

Used to approximate Left Ventricular End Diastolic Pressure

PVR (Pulmonary Vascular Resistance)

The measurement of the resistance of the pulmonary vascular bed to blood flow

RVP (Right Ventricular Pressure)

Direct measuremetn that indicates right ventricular funciton and fluid status

SI/SVI (Stroke Index/Stroke Volume Index)

Amount of blood ejeceted from the heart in 1 cardiac cycle related to BSA, ml/m^2 BSA
