VO₂ max
Maximal oxygen uptake, defined as the maximum rate at which the human body can utilize oxygen during high-intensity exercise. It is considered the gold-standard metric for assessing cardiorespiratory fitness and aerobic endurance, expressed in mL/kg/min. It is also recognized as an important physiological predictor of all-cause mortality.

PNOĒ has launched a self-administered breath analysis mask that allows users to measure VO₂ max and other metabolic indicators in just eight minutes without guidance from a professional.
VO₂ max (maximal oxygen uptake) is the core indicator measuring the maximum capacity of the human body to utilize oxygen during high-intensity exercise, and is regarded as the gold standard for cardiorespiratory fitness and aerobic endurance.
VO₂ max values are typically expressed in milliliters per kilogram of body weight per minute (mL/kg/min); the typical range for ordinary adults is 35–50, while elite endurance athletes can exceed 80 or even 90.
Multiple large-scale epidemiological studies published in JAMA and the Journal of the American College of Cardiology found that VO₂ max is one of the single strongest predictors of all-cause mortality, second only to smoking history.
Mainstream wearable devices such as Apple Watch, Garmin, and Polar all have built-in VO₂ max estimation features, but these are based on heart rate and activity data extrapolation and carry significant error.
An eight-minute test duration suggests that the PNOĒ approach may employ a submaximal testing protocol that uses mathematical modeling to estimate true VO₂ max rather than requiring exercise to exhaustion.
