How Long Can You Live With Low Oxygen Levels? 

It should be no surprise that oxygen is one of the most vital elements in human life. If your oxygen level is low, it can lead to many uncomfortable symptoms that are caused by your body not working properly. Some of the most common symptoms of hypoxemia, which is the medical term for having low oxygen levels in the blood, include headaches, shortness of breath, fast heartbeat, coughing, wheezing, and confusion. How long can you live with low oxygen levels? O2 Assist, a top oxygen supply store, answers the question in the following blog. 

How Long Can Someone Survive With Low Oxygen Levels? 

There are varying levels of hypoxemia, and the amount of time that someone can survive with this varies depending on the severity of their condition. The normal amount of oxygen in the air at any given time is normally around 21 percent. Once the level dips below 20 percent, the mildest symptoms of hypoxia begin to manifest. If these are not corrected quickly, they could easily become fatal. Once the level of oxygen goes below 15 percent, serious symptoms of hypoxia begin to show up, which means that someone is risking serious injury or even death. At 10 percent oxygen concentration, somebody has minutes or seconds to survive.
