Normal oxygen levels in the blood are typically measured as partial pressure of oxygen (PaO2) and oxygen saturation (SpO2). PaO2, measured through an arterial blood gas test, indicates the amount of oxygen dissolved in the blood and is usually expressed in millimeters of mercury (mmHg). A normal PaO2 value typically ranges from 80 to 100 mmHg. However, this can vary slightly based on factors such as altitude and individual health conditions. SpO2, measured using a pulse oximeter, represents the percentage of hemoglobin binding sites in red blood cells that are occupied by oxygen. A normal SpO2 level is generally considered to be between 95% and 100%. Values below 95% may suggest hypoxemia, or low blood oxygen levels, which can be a symptom of various underlying health problems. It's crucial to remember that these are just general ranges, and an individual's normal oxygen levels can vary. Always consult a healthcare professional for accurate interpretation of oxygen level readings and appropriate medical advice.
