QuestionChoice
Cardiac output is the volume of blood pumped out of the left ventricle per minute and is measured in litres per minute (L/min). It can be calculated by heart rate x stroke volume. Normal cardiac output is 5-6 L/min at rest. Stroke volume can be calculated by subtracting the end-systolic volume from the end-diastolic volume (end-diastolic volume – end-systolic volume).

Cardiac output is the volume of blood pumped out of the left ventricle per minute and is measured in litres per minute (L/min). It can be calculated by heart rate x stroke volume. Normal cardiac output is 5-6 L/min at rest. Mean arterial pressure can be calculated by cardiac output x total peripheral resistance.

QuestionChoice
Cardiac output is the volume of blood pumped out of the left ventricle per minute and is measured in litres per minute (L/min). Normal cardiac output is 5-6 L/min at rest. Stroke volume is the volume of blood pumped out of the left ventricle with each contraction. Stroke volume can be calculated by subtracting the end-systolic volume from the end-diastolic volume (end-diastolic volume – end-systolic volume).

A 72-year-old female attends her GP with symptoms of breathlessness on exertion. She also complains of waking up in the middle of the night gasping for breath. On examination, she has a raised JVP and her ankles have pitting oedema.

She is referred for echocardiography to assess her left ventricular function.

Which of the following describes how to calculate cardiac output?
