Web29 de nov. de 2024 · Causes. By Mayo Clinic Staff. A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there. High hemoglobin count … The human body can perform best at sea level, where the atmospheric pressure is 101,325 Pa or 1013.25 millibars (or 1 atm, by definition). The concentration of oxygen (O2) in sea-level air is 20.9%, so the partial pressure of O2 (pO2) is 21.136 kilopascals (158.53 mmHg). In healthy individuals, this saturates hemoglobin, the oxygen-binding red pigment in red blood cells. how did charles remington the hunter die https://edgeimagingphoto.com
