Q:
What are the normal oxygen saturation levels by age?

Normal Blood Oxygen Level While Sleeping

A:
For infants and children, the normal oxygen saturation level should range between 97% to 99%.

For neonates and young infants, the normal oxygen saturation level should range between 93% to 100%.

CO shares the same binding sites as O2 in blood hemoglobin (Hg), and actually has 200 times greater affinity than O2. So when you smoke, the CO travels across and prevents some Hg from picking up oxygen. The net result is that your heart starts working harder to get more blood around, which can keep up your sat levels. People afflicted by these health problems often have a lower SpO 2 average, necessitating the use of supplemental oxygen and other treatment methods. Your “Normal” SpO 2 Range. According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent.

What Are Normal Levels of Oxygen in Blood? In most cases, an oxygen level that hovers around 95 to 100% is considered healthy. Any reading below 90% is a cause of concern, which needs to be investigated by a doctor. Levels of oxygen in the body can be measured with the help of various methods. When measured by ABGs, normal oxygen levels are approximately 75-100 millimeters of mercury (mm Hg). When measured by pulse oximetry, normal oxygen levels are 95-100%. I In general, values below 55 mm Hg or 88% or less usually mean you need long-term oxygen therapy.

Study objective: To determine oxyhemoglobin saturation (O2 Sat) in healthy humans. Design: Retrospective review of all-night pulse oximetry data, carefully examined to exclude periods of motion artifact.

Is 92 Oxygen Level Low

For adults less than 70 years of age, the normal oxygen saturation level should range between 96% to 98%.

For adults aged 70 and above, the normal oxygen saturation level should be greater than 94%.
