WebOxygen delivery to the tissues. Oxygen delivery to the tissues each minute is the product of arterial oxygen content and cardiac output. Hence oxygen delivery can be compromised as much by a low haemoglobin concentration or low cardiac output as by a fall in the S aO 2.Following circulation through the tissues, the average oxygen saturation in the venous … WebAs oxygen is 21% of dry air, the inspired oxygen pressure is 0.21× (100−6.3)=19.6 kPa at sea level. Atmospheric pressure and inspired oxygen pressure fall roughly linearly with altitude to be 50% of the sea level value at 5500 m and only 30% of the sea level value at 8900 m (the height of the summit of Everest).
WebBlood gas tension refers to the partial pressure of gases in blood. There are several significant purposes for measuring gas tension.
