Answer 1

36. Convert pressure reading of 10 cmH20 to kilopascal (kPa)

1 cmH2O to kPa = 0.09807 kPa

So, 10 cmH2O to kPa = 0.98067 kPa

37. To calculate the partial pressure of oxygen when baro.etric pressure is 760 mmHg

Since inspired air is 21% oxygen and atmospheric pressure is 760 mmHg (at sea level), the partial pressure of oxygen is 0.21 x 760 mmHg = 160 mmHg . As air moves to the alveoli oxygen mixes with water ,carbon dioxide and partial pressure reduces to 100mmhg .

38. If the baro.etric pressure is 500mmhg then partial pressure of oxygen would be 0.21× 500 = 105 mmHg
