A dangerously low oxygen level is a level of oxygen in the bloodstream that is significantly below normal. Oxygen levels are normally measured in milliliters of oxygen per liter of blood (mmHg). Normal oxygen level ranges vary from person to person, but an oxygen level below 60 mmHg is considered to be dangerously low and requires immediate medical attention. Low oxygen levels can be caused by a variety of medical conditions, including asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and pulmonary embolism.
Symptoms of a Dangerously Low Oxygen Level
When oxygen levels in the body drop below normal, the most common symptoms are shortness of breath, confusion, and fatigue. Other symptoms may include rapid breathing, blue lips and fingernails, headache, dizziness, and chest pain. In severe cases, low oxygen levels can cause unconsciousness and even death.
Treatment for Dangerously Low Oxygen Levels
The treatment for a dangerously low oxygen level will depend on the underlying cause. Treatment may include oxygen therapy, medication, and lifestyle changes. In some cases, a person may need to be hospitalized and given supplemental oxygen in order to raise oxygen levels.
