When should you take action?

When reading an oximeter, an oxygen saturation level of 95-100% is considered normal for most people. However, for people with certain conditions, it is acceptable if it falls as low as 90%*.

More than 89% of your blood should be carrying oxygen, and if it is lower than this, it can be dangerous as it might be a sign of hypoxemia. This is a deficiency in oxygen reaching the body’s tissues and can cause a lot of damage.

SpO2 Range	Condition
95% to 100%	Normal
85% to 92%	Hypoxemia develops (but acceptable for those people with severe pulmonary issues)*
Below 80% to 85%	The brain does not have enough oxygen and gets affected
Below 65%	Severe hypoxemia, cyanosis (bluish discolouration of nails, lips, or skin) develops
