Under resting conditions, red blood cells move through the pulmonary capillary bed in approximately 0.75 seconds (transit time), although equilibration of oxygen and carbon dioxide takes place in about 0.25 seconds. In a diffusion limited gas exchange situation, the alveolar gas is still equilibrating with the blood cell at the…
