APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Cardiac output is the product of heart rate (HR) and stroke volume (SV) and is measured in liters per minute. HR is most commonly defined as the number of times the heart beats in one minute. SV is the volume of blood ejected during ventricular contraction or for each stroke of the heart.

Detailed explanation-2: -Cardiac output is therefore calculated using the formula: Cardiac output = Oxygen consumption / Arteriovenous oxygen gradient.

Detailed explanation-3: -Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the end-diastolic volume. Multiplying the stroke volume by the heart rate yields the cardiac output, typically reported in liters per minute.
