    The number of heart beats from 30 seconds to 1 minute after the end of the 3-minute step test is used to assess cardiovascular fitness level. The results of the test can also be used to estimate maximum oxygen consumption during exercise . [3] [4] The Tecumseh step test was originally employed in the Tecumseh Community Health Study run between ...

    en.wikipedia.org/wiki/Pulse_oximetry

    A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]

    With a maximal stress test the level of exercise is increased until the person's heart rate will not increase any higher, despite increased exercise. A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age.

  9. Cardiac output - Wikipedia

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
