Blood oxygen levels refer to the amount of oxygen that is circulating in the blood. It is measured as a percentage and should typically be between 95 and 100 percent. When the oxygen level drops below 90 percent, it is considered a medical emergency and is known as hypoxemia. Low blood oxygen levels can lead to serious health complications and can even be life-threatening. Well, to help you in knowing more about it here we are elaborating on this in detail. Let’s have a look!
What does blood oxygen level mean?
Blood oxygen level (also known as oxygen saturation or SpO2) is a measure of the amount of oxygen circulating in the body. The level of oxygen in the bloodstream is measured by a device called a pulse oximeter, which measures the proportion of oxygen-carrying hemoglobin molecules in the blood. When the body is healthy, SpO2 should be between 95% and 100%. Oxygen saturation levels below 90% indicate that the body is not receiving an adequate amount of oxygen and needs medical attention. Low oxygen levels can cause symptoms such as dizziness, rapid breathing, confusion, and an increase in heart rate. In severe cases, hypoxemia (low oxygen levels in the blood) can lead to organ damage and even death. Checking the oxygen saturation level regularly is a key part of managing a variety of medical conditions such as COPD, asthma, and heart disease.
What is a blood oxygen level test?
A blood oxygen level test is a test that is used to measure the amount of oxygen present in a person’s blood. This test is usually done in a hospital or clinic with a device called a pulse oximeter. The pulse oximeter passes a small beam of light through the tip of the patient’s finger and then uses sensors to measure how much oxygen is in the blood. Low oxygen levels can be an indication of various underlying medical conditions such as asthma, emphysema, COPD, congestive heart failure, and pulmonary diseases.
In some cases, low oxygen levels can be indicative of anemia or even shock. Anemia is a condition of low levels of red blood cells and can lead to a reduction in oxygen delivery to the body’s tissues. Low oxygen levels can also be caused by small airway obstructions such as asthma, COPD, or other respiratory disease. Additionally, high altitudes can cause low oxygen levels in the blood.
This test is often used by medical professionals to monitor patients that are undergoing certain treatments, such as those with chronic obstructive pulmonary disease (COPD). It is also used to check for other conditions such as anemia, heart failure, and shock. The results of this test can also be used to determine how well a person is able to absorb and use oxygen.

Why do I need to have my blood oxygen level tested?
Some common reasons indicating you need to get the test for blood oxygen level include:
1. Experiencing shortness of breath:
If you are experiencing shortness of breath with any physical activity, it could be an indicator that your oxygen levels are low and you should seek evaluation by a medical professional.
2. Fast breathing rate:
An increased breathing rate, or tachycardia, can be a sign of oxygen deprivation in the body and is an indication that you should have your oxygen levels tested.
3. Confusion or impaired decision-making:
Cognitive impairments such as confused thinking or impaired decision-making could be a sign of oxygen deprivation in the body and a reason to have your oxygen levels tested.
4. Paleness or blueness around lips or nails:
If you notice a paleness or blueness around your lips or nails, it could be a sign that your oxygen levels are low and that you should have your oxygen levels tested.
5. Chest pain or discomfort:
Chest pain or discomfort can be a symptom of oxygen deprivation and is a sign that you should have your oxygen levels tested.

How To normalize blood oxygen level?
Certain things that one can keep in mind to normalize blood oxygen level includes:
1. Exercise Regularly:
Exercise is one of the best ways to help your body take in and use additional oxygen. Taking a walk, running, swimming, or weight lifting can all help your body boost its overall oxygen levels.
2. Eat a Healthy Diet:
Eating healthy foods that are rich in antioxidants, such as fruits and vegetables, can help maintain a healthy blood oxygen level.
3. Get Adequate Rest:
Getting enough sleep is essential for boosting oxygen levels in your blood. A lack of sleep can negatively affect how well your body takes in and uses oxygen.
4. Avoid Smoking:
Cigarette smoke is a major source of air contamination and it can significantly reduce the amount of oxygen your blood can take in.
5. Use Supplements:
Taking certain supplements, such as iron, can help boost oxygen levels in the blood. Talk to your doctor to determine the best supplements for your individual needs.
6. Practice Deep Breathing:
Deep breathing can help the body better use oxygen. Take a few moments each day to practice deep breathing to boost oxygen levels.
7. Use Oxygen Therapy:
In some cases, your doctor may recommend oxygen therapy to help boost oxygen levels in your blood. This type of therapy involves breathing in pure oxygen through a mask that is placed over the nose and mouth.
What is a normal blood oxygen level?
A normal blood oxygen level is the amount of oxygen circulating in a person’s bloodstream. The amount of oxygen in the bloodstream is measured using a device known as a pulse oximeter and is expressed as a percentage. A normal blood oxygen level for a healthy person is between 95 and 100 percent. A lower-than-normal reading, known as hypoxemia, may indicate a breathing or circulation problem. In some cases, a person may need supplemental oxygen to get their oxygen level back up to normal.
