   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 the 1950s and 60s. [5] During this study, 2696 men and 2568 women aged between 10 and 69 years old performed the Tecumseh step test. [2]

   The normal oxygen tension in the foot is approximately 60 mmHg, and the normal chest/foot ratio is approximately 0.9. [2] Many factors can limit the accuracy of the test including edema, temperature, inflammation, medications, and stress. In addition for the measurement to be normal, all parts of the oxygenation pathway must be functioning: the ...

   The V/Q ratio can therefore be defined as the ratio of the amount of air reaching the alveoli per minute to the amount of blood reaching the alveoli per minute—a ratio of volumetric flow rates. These two variables, V and Q, constitute the main determinants of the blood oxygen (O 2) and carbon dioxide (CO 2) concentration.

   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.

   For the comfort of the patient this is done over a 15-second time period before being extrapolated to a value for one minute expressed as liters/minute. Average values for males and females are 140–180 and 80–120 liters per minute respectively. [medical citation needed]
