The accuracy of a pulse oximeter, which measures SpO2 levels, can vary depending on the device and conditions under which it is used. Generally, high-quality pulse oximeters have an accuracy range of ±2% to ±3% for SpO2 readings between 70% and 100%. However, factors such as poor circulation, skin pigmentation, nail polish, and ambient light can affect the accuracy of the readings.
