b. Cardiac output (CO) of 4 L/min
c. Pulmonary vascular resistance (PVR) of 80 dynes/sec/cm-5
d. Systemic vascular resistance (SVR) of 1800 dynes/sec/cm-5

A cardiac index of 1.2 L/min/m3 combined with the identified clinical assessment findings indicate a low cardiac output with fluid overload (bilateral crackles) requiring intervention. The remaining hemodynamic values are within normal limits: cardiac output of 4 L/min; pulmonary vascular resistance of 80 dynes/sec/cm-5; and the systemic vascular resistance of 1800 dynes/sec/cm-5.
