Dr. John Munshower answered. Family Medicine 32 years experience. A little low: Assuming you mean a "pulse ox" result, than 91% means that your are getting 91% oxygen saturation at the tips of your fingers. Normal is 97-100%. As a gauge, medicare guidelines will pay for oxygen if under 88%.
There are a lot of factors when it comes to your normal oxygen saturation level, and if you have COPD, you might find that your normal O2 saturation levels are lower than the normal range. While a “normal” reading for a healthy person is typically between 100% and 95%, a person with COPD may maintain an oxygen level of 94.
This is the body’s way of rapidly bringing oxygen saturation back to 100% and restoring the circulation of red blood cells to the tissues. People with relatively severe anemia have symptoms of hyperventilation and a rapid heartbeat due to their bodies’ constant effort to restore oxygen levels to normal.
Dr. Jonathan Richards answered. Probably not: Many people do not have an oxygen saturation of 100%. Depending on age and medical history, a saturation in the mid to high nineties is no cause for alarm. The device that estimates oxygen saturation ( pulse oximeter) may underestimate saturation if it encounters interference in the form of ambient
The drug we use most often in EMS can cause harm if we give it without good reason. In the absence of low saturations, oxygen will not help patients with shortness of breath and it may actually
