Hypoxia and hypercarbia are two terms that are used to describe the levels of oxygen and carbon dioxide in the body. Hypoxia is when the body has a low level of oxygen, while hypercarbia occurs when the body has an excessive amount of carbon dioxide.
Hypoxia
Hypoxia occurs when the body's oxygen level is too low, typically below 90mmHg. This may be caused by a decrease in oxygen supply, an increase in oxygen demand, or both. Hypoxia can lead to a variety of symptoms, including shortness of breath, confusion, and fatigue. In severe cases, hypoxia can be fatal.
Hypercarbia
Hypercarbia is when the body has an excessive amount of carbon dioxide. This is usually caused by an increase in carbon dioxide production, a decrease in carbon dioxide elimination, or both. Hypercarbia can lead to a variety of symptoms, including headache, confusion, and shortness of breath. In severe cases, hypercarbia can be fatal.
The key difference between hypoxia and hypercarbia is that hypoxia is caused by a decrease in oxygen supply, while hypercarbia is caused by an increase in carbon dioxide production. Additionally, hypoxia can lead to a variety of symptoms, including shortness of breath, while hypercarbia can lead to headaches, confusion, and shortness of breath.
