Blood Oxygen Level Chart
It depends: If you live at sea level, and the pulse oximetry machine if functioning normally, your arterial oxygen saturation should be higher than 93%. If you live at high altitude, the partial pressure of oxygen in the air is lower and, depending on how high you are, an oxygen saturation level of 93% may be normal. ...Read more
Not really: If it is a nonsmoker, then no, should be 95%+ as "normal." lower can indicate lung infection or function abnormality. Smokers or persons with lung diseases often have lower saturations like this. If no explanation, should see dr for exam and probably chest xray ; breathing treatment(s). ...Read more
Depends: On your age and condition . It is usually reported by%. For example a little baby you would want to be high, close to 100% and if sick not lower than 92% when ill and hospitalized. A normal person walking around is usually 96- 100%. If a person has a chronic lung condition lower percentages of oxygen are acceptable, down to about 88%. ...Read more
Ambient air is about: 21% o2, and healthy lungs produce a po2 of 80-100%. Babies in nicu's treated with 100% due to respiratory immaturity could get pulmonarty and retro lentar fibrosis. One does not do well with higher levels of o2. Like goldylocks, not too little, not too much: just right. ...Read more
It seems whenever i exercise, the blood oxygen level drops. Will it get better if i exercise regularly?
What is normal levels of oxygen in the blood? What is considered low and what is considered dangerous? Is levels in the 80s ok?
Oxygen level....: The oxygen saturation, or pulse oximetry, should be in the 90's normally. Any value of less than 88% on room air qualifies a patient for supplemental oxygen therapy. So, an oxygen saturation in the 80s is not normal. Your doctor will need to find out why your oxygen level is low and provide treatment. ...Read moreSee 2 more doctor answers
Oxygen in blood: The oxygen in your blood is linked to the concentration of red cells in your blood. If you are anemic, that is what is going to limit your oxygenation, not how much you exercise. Being healthier may improve your anemia. If you exercise more, you may signal your body to tell your bone marrow to make more blood. ...Read more
Low blood oxygen levels, at what number would be low enough to cause a person to fall to the floor and have a blackout?
Depends: Its the rate of fall thats more important than the actual number. When the partial pressure of oxygen falls below 55 or 88% hemoglobin saturation the delivery of oxygen to our organs begins to decrease. If your organs, like the heart , is already damaged this drop can be very dangerous. If the organs are healthy they can tolerate this drop in oxygen levels for several minutes, sometimes even longe. ...Read moreSee 1 more doctor answer
