As a medical professional with expertise in respiratory health, I can tell you that oxygen saturation is a critical measure of how well oxygen is being transported through the blood. It's the percentage of oxygen-saturated hemoglobin compared to the total amount of hemoglobin present in the blood. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the rest of the body.
Normal oxygen saturation levels are typically between 95 and 100 percent. This range is considered healthy for most individuals at sea level. However, it's important to note that oxygen saturation can be affected by various factors, including altitude, certain health conditions, and age. For instance, at higher altitudes, the atmospheric pressure is lower, which can result in slightly lower oxygen saturation levels that are still considered normal for that environment.
In summary, while 95-100 percent is the general guideline for normal oxygen saturation, individual circumstances can influence what is considered normal for a specific person.

Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.
