Put your result time into the calculator and read out your VO2 max value. From oxygen in the environment to feeding the tissues, the process has three steps: oxygenation, oxygen delivery and oxygen consumption. People who stay in intensive care units (ICU) may need the support of a ventilator . To calculate your Vo2 max, a physiologist will utilize a formula that includes the rate of your oxygen consumption during the exercise as well as your body weight.
