Fick Equation Cardiac Output Calculator
Cardiac output: Basically an increase in demand for oxygen by the body. This may be physiological (exercise) or pathological (sepsis - infection - fever) or increased metabolism (hyper active thyroid gland - hyperthyroidism) or abnormal conducts (shunting of blood). ...Read moreSee 1 more doctor answer
5 liters/min: A typical cardiac output is approximately 5 l per minute. This can vary with the size of the patient with a larger patient having larger cardiac output. 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. ...Read moreSee 1 more doctor answer
4 to 5 liters/min: Approximately 4-5 l per minute. The cardiac output is proportional to the size of the patient. You can "normalize" the cardiac output by dividing the cardiac output by the body surface area resulting in a "cardiac index". The cardiac index is typically 2-3 l per minute per meter squared. ...Read moreSee 1 more doctor answer
Venoconstriction?: Cardiac output is inversely proportional to total peripheral resistance (which is related to mean arterial pressure.) venoconstriction refers to the venous system and can't be measured. If venous return increases, preload increases, and by starling's law of the heart, cardiac output increases. However, severe venoconstriction could eventually diminish venous return and reduce co.

Natural: This is the normal pattern of the heart's output based upon the load conditions. The amount of blood filling the heart may vary mildly over time and combined with your level of activity and the force against your heart's ejection of blood (after load) the cardiac output may vary. Most important is that the output does not drop very low as in severe volume loss or weakness of the heart muscle. ...Read more
