SpO2

Definition

SpO2 stands for peripheral capillary oxygen saturation, a measure of the amount of oxygen in the blood. It is typically measured using a pulse oximeter and expressed as a percentage.

5 Must Know Facts For Your Next Test

1. Normal SpO2 levels range between 95% and 100%.
2. Low SpO2 levels can indicate hypoxemia, which can affect the pulmonary system.
3. Nutrition can influence SpO2 levels by impacting hemoglobin function and overall respiratory health.
4. Malnutrition can lead to decreased muscle mass, including respiratory muscles, affecting breathing efficiency and SpO2.
5. Certain nutrients like iron and vitamins B6, B12, and C are essential for maintaining healthy hemoglobin levels.
