Spo2 normal range: The two primary methods to

The two primary methods to measure this are: Pulse Oximetry : A non-invasive device clips onto a finger to measure oxygen saturation ( SpO2). Normal range : 95-100%. Arterial Blood Gas (ABG) Test: A blood sample taken from an artery provides detailed insights, including oxygen levels (PaO2), carbon dioxide levels, and blood pH. Test Results ... Definition: SpO2 represents the percentage of hemoglobin molecules carrying oxygen in arterial blood. A value of 95% means 95% of hemoglobin is oxygenated. Significance: Normal SpO2 (95–100%) indicates efficient oxygen delivery to tissues, essential for organ function. Readings below 90% (hypoxemia) suggest respiratory or cardiovascular issues. What is the Spo2 normal range by age chart? Measurements of arterial oxygen content in the blood reveal the amount of oxygen in the bloodstream at any time. Oxygen saturation values of 95% to 100% are generally considered normal. Values below 90% could quickly lead to serious deterioration of the condition, and values below 70% are life-threatening. Patients can deteriorate considerably before there is a drastic change in oxygen saturation.
