WebNov 1, 2024 · For most people, low cell oxygen levels are produced due to 2 effects that we considered before: constriction of arteries and arterioles (since CO2 is a most potent vasodilator) and the suppressed Bohr effect (less oxygen is released in tissues due to increased affinity of oxygen to red blood cells caused by hypocapnia). WebOnce perfusion declines and oxygen delivery to cells is inadequate for aerobic metabolism, cells shift to anaerobic metabolism with increased production of carbon dioxide and elevated blood lactate levels. Cellular function declines, and if shock persists, irreversible cell damage and death occur. on the beach atol
