What does it mean when your oxygen levels are low?

As a medical professional, I can tell you that low oxygen levels in the blood, or hypoxemia, can have a variety of implications for your health. When your oxygen saturation levels are consistently below the normal range of 95 to 100 percent, it means that your body's tissues and organs may not be receiving the amount of oxygen they need to function properly. This can lead to a range of symptoms and health issues, depending on the severity and duration of the hypoxemia. Factors that can contribute to low oxygen levels include lung diseases such as chronic obstructive pulmonary disease (COPD), pneumonia, or asthma; heart problems that affect the circulatory system; high altitude; and certain medications or toxins. It's also important to note that smoking can significantly reduce oxygen levels in the blood. Symptoms of low blood oxygen can include shortness of breath, rapid breathing, confusion, fatigue, and bluish skin color (cyanosis). If you suspect that you have low oxygen levels, it's crucial to seek medical attention promptly, as untreated hypoxemia can lead to serious complications, including organ failure and respiratory failure.

My O2 saturation is 93-94%. ... 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.
