A normal oxygen level for a healthy person at sea level is between 95% and 100%. This is measured using a pulse oximeter, which clips onto a finger and measures the oxygen saturation in your blood.
People with chronic lung diseases like COPD or pneumonia may have normal oxygen levels around 90%. At higher elevations, oxygen saturation levels may be slightly lower.
It's important to note that oxygen levels can vary depending on factors such as altitude, activity level, and underlying health conditions.
If you have concerns about your oxygen levels, talk to your doctor. They can determine if your levels are within a healthy range and recommend appropriate treatment if needed.
