Calculate Cardiac Output in Post-Operative Patient

A 68-year-old female patient is being monitored in the intensive care unit following a coronary artery bypass graft surgery. In the post-operative period, the critical care nurse observes that the patient's mean arterial pressure (MAP) is 45 mmHg, heart rate is 120 beats per minute, and she is experiencing significant hypotension. Given these parameters, the nurse must calculate the patient's cardiac output. The formula used to determine cardiac output (CO) is:
CO = Stroke Volume (SV) × Heart Rate (HR). If the normal stroke volume is approximately 70 mL per beat, complete the following calculation to determine the patient's cardiac output. Cardiac Output = L/min. Note that to convert from mL/min to L/min, you will divide the total by 1000.
