SUMMARY
The fractional saturation of hemoglobin (YO2) at a venous O2 pressure of 30 torr can be calculated using the equation YO2/(1-YO2) = (pO2/p50)^n. Given that the p50 for hemoglobin is 26 torr and the Hill constant (n) is 3, the calculation yields YO2 = 0.61. This indicates that at 30 torr, hemoglobin is approximately 61% saturated with oxygen, demonstrating the relationship between partial pressure and hemoglobin saturation.
