It causes symptoms like headache, difficulty breathing, rapid heart rate and bluish skin. Many heart and lung conditions put you at risk for hypoxemia. It can also happen at high altitudes. Hypoxemia can be life-threatening. If you are experiencing symptoms of hypoxemia, call 911 or go to the ER. tsing riverWebThere are sugars acting with your oxygen in your cells. Thousands of reaction occur when there is enough oxygen. Glucose + Oxygen = ATP + Carbon Dioxide + Water. C6H12O6 + 6O2 = 6CO2 + 6H2O +ATP. So, if your oxygen is not enough, you are undergoing a process that produce little ATP for use, glycolysis. tsingroc

"WebIn critically ill patients, high blood lactate levels develop from a combination of inadequate oxygen delivery secondary to poor perfusion (in terms of both perfusion pressure and flow), impaired cellular oxygen utilization from mitochondrial damage, and reduced hepatic clearance of lactate.
