    Glossary Oxygen Levels

    amount of oxygen in blood or environment, crucial for health

    Oxygen levels, also known as oxygen concentration or oxygen saturation, refer to the amount of oxygen present in the blood or a given environment. In a medical context, oxygen saturation (often measured as SpO2) indicates the percentage of hemoglobin molecules in the bloodstream that are bound with oxygen, with normal levels typically ranging from 95% to 100%. Monitoring oxygen levels is crucial for assessing respiratory and overall health, as low levels can indicate conditions such as hypoxia or respiratory distress.
