| 90-94% | Low (seek medical advice) |
| Below 90% | Critical (seek immediate medical attention) |
Understanding these levels is the first step in recognizing when something might be wrong with your oxygen saturation.
Common Causes of Low Oxygen Levels
Low oxygen levels can result from a variety of factors, including respiratory and cardiovascular conditions. Asthma, chronic obstructive pulmonary disease (COPD), and pneumonia are common respiratory issues that can reduce oxygen levels. Similarly, heart failure and anemia can impair the body’s ability to transport oxygen efficiently.
Environmental factors, such as high altitude or air pollution, can also play a role. For instance, at higher altitudes, the air contains less oxygen, which can lead to hypoxia. Lifestyle choices, like smoking or a sedentary routine, can further exacerbate the problem.
Here’s a list of common causes:
- Respiratory conditions (e.g., asthma, COPD, pneumonia)
- Cardiovascular issues (e.g., heart failure, anemia)
- Environmental factors (e.g., high altitude, pollution)
- Lifestyle factors (e.g., smoking, lack of exercise)
Understanding these causes can help you take preventive measures and seek timely medical intervention.
Physical Symptoms of Low Oxygen Levels
One of the most noticeable signs of low oxygen levels is shortness of breath, also known as dyspnea. This occurs when your body struggles to get enough oxygen, leading to rapid or shallow breathing. Fatigue and weakness are also common, as your muscles and organs aren’t receiving adequate oxygen to function properly.
Dizziness or lightheadedness is another symptom, often resulting from reduced oxygen supply to the brain. If you experience these symptoms frequently, it’s essential to monitor your oxygen levels and consult a healthcare professional.
