Pulse Oximeter Readings Chart
What is pulse oximetry, and why is it important in COVID-19?
Pulse oximetry is a crucial method for checking oxygen levels in the blood, especially for patients with COVID-19. Many individuals infected with COVID-19 may have low oxygen levels even if they feel fine. This makes low oxygen levels an early warning signal that shows when medical help might be necessary. A pulse oximeter is a small device that measures the percentage of hemoglobin in the blood that is carrying oxygen. It is considered a vital sign, similar to how we view blood pressure. The device works by shining a beam of red light through the fingertip, allowing us to determine the oxygen saturation level (SpO2) based on how much light is absorbed.
Understanding Normal Pulse Oximeter Readings
What are normal levels, and when should I worry?
Normal SpO2 levels are typically at least 95%. However, for patients with chronic lung issues or sleep apnea, a normal reading might be around 90%. If someone with suspected or confirmed COVID-19 has an SpO2 level of 90% or lower, it is essential to consult medical professionals. Such individuals might require supplemental oxygen or other treatments.
If oxygen supply is available, it should be administered when saturation levels drop below 85%. Levels between 80% and 90% and a decline in readings over time may indicate severe health issues and possible rapid deterioration.
