As a specialist in the field of respiratory health, I can provide you with information regarding oxygen levels in individuals with Chronic Obstructive Pulmonary Disease (COPD). Normal oxygen saturation levels for a healthy individual are between 95 to 100 percent. However, for someone with COPD, the target oxygen saturation levels might be slightly lower. It's important to note that the optimal oxygen level can vary depending on the severity of the disease and the individual's specific health conditions. In general, healthcare providers aim to maintain oxygen saturation levels above 90 percent to avoid hypoxemia, which is a condition characterized by low oxygen levels in the blood. For COPD patients, especially those with severe disease, healthcare providers may accept a slightly lower saturation level, such as in the mid-80s to low 90s, to avoid potential complications from high oxygen therapy, such as oxygen toxicity. It's crucial for COPD patients to have their oxygen levels regularly monitored and to follow the treatment plan prescribed by their healthcare provider. read more >>

The oxygen carried in the blood is usually referenced as a percentage of the maximum amount of O2 the blood can carry. Normal oxygen saturation levels range from 95 to 100 percent. Simply put, oxygen levels under 90 percent are considered low, and are also known as hypoxemia.read more >>
