Barometric pressure varies with altitude.
Normal, sea level, pressure is 760 mmHg. The higher the barometric pressure, the higher the partial pressure of oxygen, and therefore the greater the ability to push oxygen through to the mitochondria, where it facilitates energy production. The same applies in the reverse too. The higher the altitude, the lower the barometric pressure, and the harder it is to get oxygen to the mitochondria. You have to subtract 47 mm Hg in order to account for water vapor in the air.
