Arterial blood gases normal values

Respiratory alkalosis is associated with low partial pressure of02 (25 to 35 mm Hg) and alkaline pH, but normal bicarbonate. The first two values are measured by arterial blood gas, which also yields partial pressure of carbon dioxide and arterial oxygen saturation. Circulating arterial oxygen saturation can also be measured by an oximeter, which is a noninvasive method that is fairly accurate and useful at the patient s bedside. 

Liver transplantation Like hepatorenal syndrome (s. p. 330), HPS (probably only type 1) is, in principle, reversible after transplantation of the liver. The postoperative prognosis depends on the severity of hypoxaemia prior to transplantation (postoperative lethality is < 5% if preoperative hypoxaemia is > 50 mm Hg). An increase in arterial PO2 when the patient is inhaling 100% O2 in a horizontal position is a good prognostic sign for transplantation. It was possible to demonstrate improvement and normalization regarding arterial blood gas values and intrapulmonary shunt volumes as... 

Cellular hypoxia, which may be present despite a normal arterial blood gas value. 

In the body, the concentration of carbonic acid is closely associated with the partial pressure of CO2, Pc02- Table 14.10 lists the normal values for arterial blood. If the CO2 level rises, increasing [H2CO3 ], the equilibrium shifts to produce more HsO, which lowers the pH. This condition is called acidosis. Difficulty with ventilation or gas diffusion...
