Question

The cardiac reserve refers to the maximum percentage of increase in cardiac output that can be achieved above the normal resting level. What is the normal young adults percentage cardiac reserve?

Answer 1

The percentage for normal young adults usually lie between 300 and 400

Step-by-step explanation:

Cardiac reserve could simply mean the difference between the rate at which the

heart pumps blood and its maximum capacity for pumping blood at

any given time.

Over the history of the test,Cardiac reserve has been measured in different ways with it been expressed in terms of percentage.

In healthy young adult,

the cardiac reserve is 300 to 400 per cent.

In athletically trained

persons, it is occasionally 500 to 600 per cent. But in heart failure,

there is no cardiac reserve.

Any Issue that prevents the heart from pumping blood satisfactorily

will reduce the cardiac reserve. This can result from ischemic heart

disease, primary myocardial disease, vitamin deficiency that affects

cardiac muscle, physical damage to the myocardium, valvular heart

disease, and many other factors.

Answer 2

300% - 400%

Step-by-step explanation:

The cardiac reserve is in the range of 300 to 400 percent (300% - 400% ) in normal young adults, while this percentage can be increased to 600% in trained athletes
