Instead, the test uses a sensor to read wavelengths reflected from the blood. This calculates hemoglobin saturation of oxygen at various altitudes. This 90% cutoff was used to adjust for the altitude (5280 ft). Theyll place a bandage over the site, and youll be finished. Oxygen "hitches a ride" on the hemoglobin as it circulates until it gets dropped off to the body's tissues. Rojas-Camayo J, Mejia CR, Callacondo D, et alReference values for oxygen saturation from sea level to the highest human habitation in the Andes in acclimatised persons. With anemia, the blood supply to the tissues is reduced because there are not enough healthy red blood cells with hemoglobin to carry oxygen.

If all 10 of them are full, their SpO2 is 100% but they are carrying way fewer people around than Town As. Although the percentage of oxygen in inspired air is constant at different altitudes, the fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen and hence the driving pressure for gas exchange in the lungs. What Happens When Your Blood Isn't Carrying Enough Oxygen? The normal measurement range for that test. Low blood oxygen levels indicate that your lungs and/or circulatory system may not be working as they should. Therefore, the determination of a representative SpO 2 value is difficult.

Four participants of an expedition (6013 m; Pakistan), familiar with pulse oximetry at altitude, wrote down the representative value of the measurement interval of 3 min (SpO2visual) according to their individual observation. Anyway, the measurements have to be done in the continuous mode of the pulse oximeter over a sufficient timeframe (3 SpO2-fluctuation cycles; 2-3 min). For these reasons, clinical decisions should not be based on small differences in saturation over time or Altitude adjusted saturation of 90% based on elevation (5280ft) cannot be generalized to lower elevation population centers without individualized data / calculations. There are lots of potential causes of a low reading on a pulse oximeter. However, it can also happen when: Generally speaking, an oxygen saturation level below 95% is considered abnormal.
