As a respiratory expert with a focus on pulmonary health, I can explain the implications of low oxygen levels in the blood. When oxygen levels are low, it's referred to medically as hypoxemia. This condition occurs when the amount of oxygen in the blood is below the normal range. Normal oxygen saturation levels, as measured by a pulse oximeter, are typically between 95 and 100 percent. When these levels drop, it can be due to various factors such as lung disease, high altitude, certain medications, or other health conditions that affect the respiratory system. Low oxygen levels can lead to a range of symptoms including shortness of breath, rapid heartbeat, confusion, and fatigue. If not addressed, severe hypoxemia can lead to organ damage, particularly to the brain and heart, and can be life-threatening. It's important to note that hypoxemia is a serious medical condition that requires prompt attention from healthcare professionals. Treatment will depend on the underlying cause and may involve supplemental oxygen, medication, or other interventions. read more >>

Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has fallen below normal levels, due to one or more of many different causes. Under most circumstances, breathing room air, normal readings range from 95 to 100 percent.read more >>
