As an anesthesiologist and critical care intensivist, it is mandatory to have thorough knowledge of variable partial pressure of oxygen, at different fraction of inspired oxygen (FiO2), and effect of various atmospheric pressures in alveoli, diffusion, and transport of oxygen to tissue. The partial pressure of oxygen in arterial blood gas shall always be expressed with respect to the atmospheric pressure and FiO2; unless these conditions are mentioned, one may not be able to assess the exact respiratory status of patient.
