Pressure of Inspired Oxygen Calculator

Simplify the computation of Partial Pressure of Inspired Oxygen (Sea Level) with our free online Medical Calculators.

At sea level, where atmospheric pressure equals 760 mm Hg, representing the force of a mercury column 760 mm high, our tool accurately measures the Partial Pressure of Oxygen. With the atmosphere containing 21% oxygen, simply multiply 0.21 by 760 to derive the partial pressure of O2, resulting in 160 mm Hg. Simplify your calculations effortlessly!
