Use th 1. What is the partial pressure of oxygen at sea level for dry air? 2. What is the partial pressure of oxygen in the outside air if saturated with water vapor a 37 degrees C (water vapor partial pressure = 47 mm Hg)? The alveoli in your lungs are saturated with water vapor (partial pressure In addition, carbon dioxide levels are elevated (partial pressure 45 mm Hg) and the oxygen levels therefore reduced by this amount? What is the partial pressure of oxygen in your alveoli? 3 47 mm Hg) 100 90 80 · 60 30 20 10 100 mm Hg 20 40 0 12 kPa 8 Partial pressure of O, in blood Using the oxygen dissociation curve, determine the saturation % of hemoglobin in the

Explanation / Answer

Atmospheric pressure at sea level is 760mm hg

Concentrate of oxygen in air is 21%

So partial pressure of oxygen will be total pressure ×concentration of oxygen =o. 21×760~160mmhg.

As air is inspired because of humidication water vapour reduces partial pressure of oxygen to 150mm hg.
