Webb8 juni 2024 · The pressure of the atmosphere at sea level is 760 mm Hg. Therefore, the partial pressure of oxygen is: PO 2 = (760 mm Hg) (0.21) = 160 mm Hg, while for carbon dioxide: PCO 2 = (760 mm Hg) (0.0004) = 0.3 mm Hg. At high altitudes, P atm decreases, but concentration does not change; the partial pressure decrease is due to the reduction … WebbCustomary pressure units are the atmosphere (atm) (1 atm = 1.013x105 Pa), the bar (b) (1 b = 1x105 Pa), the millibar (mb) (1 mb = 100 Pa), and the torr (1 torr = 1 mm Hg = 134 Pa).
