Blood Oxygen Saturation Levels Chart
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
My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?
In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?
Sleep apnea: Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition , there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake. ...Read moreSee 2 more doctor answers
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? Other medical conditions such as congestive heart failure with volume overload are frequently seen in elderly patients. Other heart conditions and pulmonary conditions can cause this as well. In a young healthy person such as yourself a panic attack seems more likely. See your Dr ...Read more
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
Depends how low: Down to about 80% there isn't much effect at all at least for short periods of time. Longer periods weeks to months can have cognitive effects. Below 80% saturation there can be clear effects on judgment even for brief periods. The lower the saturation the bigger the effect. ...Read moreSee 1 more doctor answer
