For blood oxygen saturation level - what is the fatal and normal range?

For blood oxygen saturation level - what is the fatal and normal range?

Oxygen sat curve: If you look at the p50 or oxygen saturation curve, anything above 90% is ok for the hemoglobin to unload as it gets into the tissues and supply them. As the curve goes down to 75% about pao2 of 45, this nears the saturation in the veins where unloading of oxygen to the tissues including heart muscles becomes difficult and there will be eventual death as it gets lower than that. ...Read more

Why do I get daily attacks of shortness of breath when my peak flow, oxygen saturation, pulse, temperature, blood test and EKG results are all normal?

Breath: Many things can cause you to feel short of breath. One of the most common is a panic attack. Are you prone to them?

What helps the body maintain a healthy oxygen saturation levels?

O2 goes into lung: Traverse the interstitial to the blood vessel wall to the blood cells goes to tissues and be delivered. Normal saturation therefore depends on the oxygen source, healthy alveoli with enough surface area, thin and healthy interstitial and blood vessel wall and normal and adequate blood cells and healthy consumption of o2. That is the balance. ...Read more

How much does a low oxygen saturation level affect judgment?

Oxygen: A low oxygen saturation definitely affects judgment. Your brain is one of the organs that is heavily dependent on proper oxygenation. If you decrease the oxygen saturation, judgment may be impaired. ...Read more
