Oxygen Limit

The oxygen limit is the lowest oxygen saturation in the blood at which normal functioning of the body is possible. This concept is used in medicine and physiology to describe how the body reacts to insufficient oxygen supply.

The oxygen limit depends on many factors, including age, gender, physical activity and health status. In healthy people, the oxygen limit is usually about 95% - this means that with an oxygen concentration in the air of about 21%, the body can function normally. However, some people may have a lower oxygen limit, which can lead to various diseases and health problems.

One example where the oxygen limit plays an important role is hypoxia, a condition where oxygen levels in the blood drop below normal. Hypoxia can occur in various diseases, such as asthma, heart failure, anemia and others. In these cases, the body's oxygen limit may be reduced, leading to serious health consequences.

To maintain a normal oxygen limit, you need to monitor the oxygen level in the air and exercise regularly. It is also important to monitor your health and consult a doctor at the first signs of illness.

The oxygen limit is the minimum saturation of blood (hemoglobin) with oxygen at which a normal level of vital activity of the body is possible (Arterial oxygenation = SpO2 minimum 94%). At lower levels - hypoxia. If on the contrary - saturation is above 95% - hypercapnia. The oxygen threshold is the threshold of the right-shifted O dissociation curve
