Question

A patient presents for her annual physical examination in seemingly good health. However, she is concerned about her heart and you proceed to work up an examination of cardiovascular function. She has a blood pressure of 128/83 mm Hg, and an echocardiogram that end-diastolic volume is 140 mL and end-systolic volume is 80 mL. You estimate this patient's cardiac output as: a. 4.7 L/minute b. 6.3 L/minute c. 4.4 L/minute d. 5.2 L/minute e. 5.5 L/minute

Step 1

Cardiac output (CO) is the volume of blood the heart pumps per minute. It can be calculated using the formula: CO = Heart Rate (HR) x Stroke Volume (SV), where Stroke Volume is the volume of blood pumped out of the ventricle with each heartbeat. Show more…
