Hypoxia is a condition in which the oxygen levels are lower than normal, while hypoxemia is a condition in which the oxygen levels in the blood are lower than normal.
Hypoxia
Hypoxia occurs when the oxygen level in the air or in the environment is lower than normal. This can be due to a variety of factors, including altitude, pollution, and a decrease in the number of oxygen-producing trees or plants in the environment. Hypoxia can also occur in enclosed spaces, such as a submarine or a mine, due to a lack of oxygen. Symptoms of hypoxia can include difficulty breathing, dizziness, and confusion.
Hypoxemia
Hypoxemia is a condition in which the oxygen level in the blood is lower than normal. This can be caused by a variety of factors, including lung diseases such as asthma or COPD, cardiovascular diseases such as heart failure or a pulmonary embolism, or other medical conditions such as anemia or sleep apnea. Symptoms of hypoxemia can include shortness of breath, fatigue, and confusion.
In summary, hypoxia is a condition in which the oxygen level in the air or in the environment is lower than normal, while hypoxemia is a condition in which the oxygen level in the blood is lower than normal.
