Why is it important to monitor a patient's oxygen saturation levels?

Monitoring a patient's oxygen saturation levels is vital because it directly reflects the adequacy of oxygenation within the body. Oxygen saturation, measured as a percentage, indicates how well oxygen is being transported in the bloodstream to the tissues. Proper oxygen levels are crucial for cellular function and overall metabolic processes. When saturation levels fall below normal ranges, it may signal respiratory distress, cardiac issues, or other underlying health concerns that require immediate intervention to prevent hypoxia and related complications. In clinical practice, maintaining adequate oxygenation is essential for patient safety and improving outcomes.
