Calculate Cardiac Output in MI Patient

A 65-year-old male patient presents to the emergency department with severe chest pain that started suddenly while he was at rest. His past medical history includes hypertension and hyperlipidemia. Upon assessment, the nurse notes diaphoresis, shortness of breath, and an elevated heart rate of 110 bpm. An ECG shows ST-segment elevation in the inferior leads. The physician suspects an inferior myocardial infarction (MI) due to occlusion of the right coronary artery (RCA).

In order to assess the effectiveness of the initial treatment for this patient, the nurse plans to monitor the patient's cardiac output (CO). The formula for calculating cardiac output is:

CO = HR x SV,

Where:

HR = heart rate (in beats per minute)

SV = stroke volume (in milliliters)

If the nurse anticipates that the heart rate will stabilize at 85 bpm and the stroke volume will be estimated to be 70 mL after the initial interventions, the nurse needs to fill in the blank below for the expected cardiac output:

CO = _______________
