Oxygenation

Definition

Oxygenation is the process by which oxygen molecules are absorbed into the bloodstream from the alveoli in the lungs. It is crucial for maintaining cellular function and overall metabolic processes.

5 Must Know Facts For Your Next Test

1. Oxygenation primarily occurs in the alveoli, where gas exchange takes place.
2. Hemoglobin in red blood cells binds to oxygen, facilitating its transport throughout the body.
3. Hypoxemia refers to low levels of oxygen in the blood and can result from impaired oxygenation.
4. Nurses must monitor patients' oxygen saturation levels using pulse oximetry to ensure adequate oxygenation.
5. Conditions like Chronic Obstructive Pulmonary Disease (COPD) and pneumonia can severely impact effective oxygenation.
