However, despite rather large increases in Pa O2 with hemodilution (mean increases of 50, 98, and 72 mmHg in the three groups), the authors suggest that the changes were not statistically significant. Webb16 aug. 2016 · P O₂ in the body cells is less than 40 mmHg. Because P O₂ in the systemic capillaries is greater than the partial pressure in the body cells, oxygen diffuses from the blood and into the cells.
