Hypoxemia

Definition

Hypoxemia is a condition characterized by abnormally low levels of oxygen in the blood, specifically in the arteries. It can lead to various symptoms such as shortness of breath and increased heart rate.

5 Must Know Facts For Your Next Test

1. Hypoxemia is often detected using arterial blood gas (ABG) analysis or pulse oximetry.
2. Common causes include respiratory disorders like asthma, COPD, pneumonia, and pulmonary embolism.
3. Symptoms may include cyanosis, confusion, restlessness, and tachypnea.
4. Management of hypoxemia usually involves oxygen therapy to restore adequate oxygen levels in the blood.
5. Chronic hypoxemia can result in complications such as pulmonary hypertension and right-sided heart failure.
