There are minimal data to define normal oxygen saturation (SpO2) levels for infants within the first 24 hours of life and even fewer data generalisable to the 7% of the global population that resides at an altitude of >1500 m. The aim of this study was to establish the reference range for SpO2 in healthy term and preterm neonates within 24 hours in Nairobi, Kenya, located at 1800 m. A random . Your doctor will let you know whats normal for your specific condition. This means that a pulse oximeter reading may be anywhere from 2% to 4% higher or lower than the actual oxygen level in arterial blood.

A pulse oximeter can quickly detect this drop in oxygen saturation, alerting people of the need for medical intervention. Pulse oximeter accuracy and limitations: FDA safety communication. With the help of a professional pulse oximeter, this indicator will be monitored. Normally, a PaO2 reading below 80 mm Hg or a pulse ox (SpO2) below 95 percent is considered low. Obesity, smoking, old age are factors that affect oxygen saturation making it lower. An oxygen saturation of 95 to 100 percent is normal for healthy children and adults.
