A simple measurement — the cardiorespiratory optimal point (COP) — could predict how long someone will live or the severity of their heart failure,
…
The COP is a measure of the minimum number of liters of air during breathing required to move one liter of oxygen through the bloodstream. The lower the COP the better, because this means that someone is working less strenuously than someone else to transport the same amount of oxygen, denoting a more efficient interaction between their heart and lungs.
