The volume of blood pumped by a ventricle in one minute. Usually expressed as CO = SV × HR, or cardiac output equals stroke volume times heart rate.
The amount of blood pumped per unit of time, in liters per minute.
The quantity of blood pumped by the heart measured in a specific unit of time is equal to the heart rates times the stroke volume.
The volume of blood expelled by each ventricle in a specific time, usually between 4.8 and 5.31/min (litres per minute).
The quantity of blood discharged from the left ventricle per minute. Normal cardiac output at rest is 3.0 L/m² of body surface per minute.
Amount of blood expelled by the ventricles of the heart in a given period of time. A normal resting adult has a cardiac output of 2.5 to 4.2 liters per minute per square meter (L/min/m²).
The amount of blood the heart pumps per minute. Cardiac output is reduced in people with heart failure or those who have had a heart attack that injured the heart muscle. Cardiac output gives doctors a sensitive indicator of changes in the heart’s functioning efficiency and provides an early warning of developing problems. The presence of weakness, fatigue, dizziness, hypotension (low blood pressure), and cold extremities caused by poor blood flow can lead doctors to suspect poor cardiac output, in which case an echocardiogram can measure the pumping action of the heart and can indirectly assess cardiac output.
The volume of blood pumped out per minute by the ventricles of the heart. It is one measure of the heart’s efficiency. At rest, the heart of a healthy adult will pump between 2.5 and 4.5 litres of blood every minute. Exercise will raise this to as much as 30 litres a minute but, if this figure is low, it suggests that the heart muscle may be diseased or that the person has suffered severe blood loss.
The volume of blood pumped out by the heart in a given space of time. A normal heart in a resting adult ejects from 2.5 to 4 liters of blood per minute.
Cardiac output refers to the volume of blood that the heart pumps in one minute, serving as a crucial measure to evaluate the heart’s efficiency. In a healthy adult at rest, the heart typically pumps between 2.5 and 4.5 litres of blood per minute. However, during exercise, the cardiac output can increase significantly, reaching up to 30 litres per minute. This heightened output reflects the heart’s ability to meet the increased demand for oxygen and nutrients during physical activity. Conversely, a low cardiac output during exercise may indicate heart muscle damage or significant blood loss, necessitating further medical investigation to identify the underlying cause.
