CVTT 1304 - Intro to Cardiac Calculations I.docx

O2 consumption

The amount of oxygen consumed by the body in a given time, usually measured in milliliters per minute per square meter of body surface area.

O2 capacity

The total amount of oxygen that can be carried by hemoglobin in the blood, calculated by multiplying the hemoglobin level by 1.36 milliliters of oxygen per gram of hemoglobin.

Ao O2 content

Oxygen content in the aorta, calculated by multiplying the O2 capacity by the O2 saturation.

SVC O2 content

Oxygen content in the superior vena cava.

MV Saturation

Saturation of oxygen in the mitral valve.

Simplified cardiac output

Calculation of cardiac output using the product of stroke volume and heart rate.

Fick cardiac output

Calculation of cardiac output using oxygen consumption and the AVO2 difference.

Stroke volume

The volume of blood pumped out by the heart in one beat.

Normal range for aortic valve area

The typical range of the cross-sectional area of the aortic valve.
