Values for cardiac output are usually denoted as L/min. For a healthy person weighing 70 kg, the cardiac output at rest averages about 5 L/min; assuming a heart rate of 70 beats/min, the stroke volume would be approximately 70 mL.
Normal Output. It’s different for different people, depending on their size. Usually, an adult heart pumps about 3-4 liters of blood per minute at rest. But when you run or exercise, your heart may pump 3-4 times that much to make sure your body gets enough oxygen and fuel.
Average Output. The cardiac output for the average adult at rest is about 5 L per minute, but this can vary from 4.8 L to 6.4 L, according to MSU. However, this increases significantly during exercise. For untrained people, the average maximum cardiac output is 14 to 20 L per minute. People in extremely good shape, such as professional athletes,
On average, a healthy adult’s heart will pump 5 L every minute, meaning the average cardiac output (or CO) is approximately 5 L/min. Now, the typical adult has approximately 5 L of total blood volume. That means that every minute, while average Joe is sitting at his …
When the cardiac output is normalized for the size of the patient, this is called the cardiac index. A typical cardiac index would be 2.5. A number of medical conditions, such as fever or anemia, can increase the cardiac output. A typical cardiac output is approximately 5 l per minute.
Medical Definition of Cardiac output. The amount of blood put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume and the heart rate determine the cardiac output. A normal adult has a cardiac output of 4.7 liters (5 quarts) of blood per minute.
Necessarily, the cardiac output is the product of the heart rate, which is the number of beats per minute, and the stroke volume, which is amount pumped per beat. The cardiac output is usually expressed in liters/minute. For someone weighing about 70 kg (154 lbs), the cardiac output at …
For a young, healthy man, resting cardiac output is roughly 5 l/min (70 ml stroke volume×72 beats per minute). For women, this value is 10–20% lower. Figure 6.5 depicts cardiac output curves for the normal heart and for hypoeffective and hypereffective hearts at increasing levels of right atrial pressure.
Cardiac Output. Cardiac Output (CO) is the amount of blood the heart pumps from each ventricle per minute. It is usually expressed in litres per minute (L/min). CO = HR x SV. Changes in either HR or SV can alter CO. Impaired regulation of SV (including preload, afterload and contractility) can have a significant adverse affect on CO.
Aug 22, 2008 · Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload. Understanding of the applicability and practical relevance of each of these four components is important when interpreting cardiac output values.

cardiac output the effective volume of blood expelled by either ventricle of the heart per unit of time (generally per minute); it usually refers to left ventricle output. It is equal to the stroke volume multiplied by the heart rate.Normal values are 4 to 8 liters per minute.
