Cardiac Output (CO) : - Amount of blood pumped through the heart each minute - Normal 4-8 L/min (varies significantly depending on body size) - Determined by stroke volume and heart rate; CO= SV x HR - Cardiac Index is the cardiac output corrected for body size and more specific than CO; use this in obese pts (CI= CO/BSA; Normal 2.4-4 L/min) - Obtained through a pulmonary artery catheter Nursing Assessment of Cardiac Function : Increased Preload= increased volume-blood backs up (right h...
