Jun 07, 2023 By Madison Evans

Do you ever worry if your blood oxygen levels are lower than they should be? Low Oxygen in the bloodstream (hypoxemia) is a dangerous medical condition that can worsen certain underlying health conditions, such as asthma and COPD. As such, it’s important to understand what normal levels of oxygen in the bloodstream look like, and how to detect warning signs for hypoxemia. In this article. we will discuss why checking your blood oxygen level is important, as well as help you understand what levels signify when something may potentially be wrong with your health.

What is normal blood oxygen level and why is it important to know your levels?

A normal blood oxygen level is an essential indicator of your overall health. The typical range for blood oxygen levels is between 95% and 100%. If your blood oxygen level falls below this level, it may indicate a respiratory problem, such as asthma or pneumonia. Knowing your blood oxygen level is critical, as it can help your doctor diagnose respiratory illnesses and monitor the effectiveness of treatments. Additionally, individuals who suffer from chronic conditions such as heart or lung disease can benefit from monitoring their blood oxygen levels. By measuring your blood oxygen level, you can take control of your health and ensure you are receiving the necessary medical attention to manage any respiratory conditions.

How do you measure your blood oxygen level and what are the various testing methods available?

Knowing your blood oxygen level is important, especially for those who are dealing with respiratory problems. There are various methods to measure your blood oxygen level. The most common method is using a pulse oximeter, which is a small device that clips on to your finger. It works by shining a light through your finger and measuring the amount of light that passes through to determine your oxygen level. Another method is arterial blood gas analysis, which involves drawing blood from an artery in your wrist and analyzing the oxygen and carbon dioxide levels. This method is more invasive and usually reserved for hospitalized patients.

Lastly, a continuous positive airway pressure (CPAP) machine can also monitor your blood oxygen level while you sleep. Understanding the different methods available can help you better monitor your oxygen level and work with your healthcare provider to optimize your respiratory health.

What could be the signs and symptoms of abnormal oxygen levels in the blood?

Abnormal oxygen levels in the blood can be a serious concern and should not be taken lightly. There are several signs and symptoms that may indicate an issue with oxygen saturation levels, such as shortness of breath, confusion, fatigue, blue-tinged skin, rapid heart rate, and chest pain.

In more severe cases, low oxygen levels can lead to respiratory failure and require immediate medical attention. It's important to monitor oxygen saturation levels, especially in individuals with pre-existing respiratory conditions, and seek medical advice if any of these symptoms appear. Early detection and treatment can prevent complications and even save lives.

What lifestyle changes can you make to improve your blood oxygen level?

Maintaining good overall health is essential to improve your blood oxygen levels. Lifestyle changes that can positively impact your blood oxygen level include regular exercise, quitting smoking, and paying attention to your breathing technique while exercising. In addition, improving your diet with nutrient-rich foods such as leafy green vegetables and lean proteins can also help. Along with making these changes, it's also important to stay hydrated and get sufficient rest to improve your oxygen levels. By implementing these lifestyle changes, you can help your body receive the oxygen it needs to function at its best.

When should you see a doctor about low/high oxygen levels?

Oxygen is essential for our body's functioning, and any significant fluctuations in its levels can cause severe health issues. Therefore, it is crucial to understand when you should see a doctor about low or high oxygen levels in your body. If you notice symptoms like shortness of breath, wheezing, confusion, blue tint on lips or nails, chest pain, or a severe headache, it is a red flag that your oxygen levels may be too low or high. In such a situation, it's best to seek medical attention immediately, as untreated low or high oxygen levels can lead to significant complications.

Certain conditions like asthma, COPD, and pneumonia can also lead to low oxygen levels and demand medical intervention. Remember, it's always better to be safe than sorry, and a doctor's consultation can help diagnose and treat the underlying issue before it becomes severe.

Recommended supplements that can help raise your blood oxygen levels naturally

Ensuring that your blood oxygen levels stay at a healthy level is essential for good health. While there are medications that can help, incorporating recommended supplements into your daily routine can offer a natural boost. Among them, iron supplements can improve the amount of oxygen that can be transported by your blood cells, while vitamin C can help reduce the risk of low oxygen levels. Omega-3 fatty acids have a range of benefits, including improving blood flow and increasing oxygen in the body.

Additionally, magnesium supplements can help improve lung function and boost oxygen levels. As with any supplement, it's important to talk to your doctor before starting a new regimen, but these natural methods can help keep your blood oxygen levels at a healthy level.


Keeping a healthy oxygen level is essential for wellbeing and overall health. While there are medical treatments for when oxygen levels become too low/high, being aware of the signs and symptoms can help reduce the risk of it occurring in the first place. Additionally, natural methods such as lifestyle changes and supplements can be beneficial in maintaining a good oxygen level. This blog post has offered an overview of what normal oxygen levels are, how to measure them, potential causes of abnormal levels, lifestyle changes for improved oxygen levels, as well as supplements that can help improve oxygen levels naturally. Ultimately, individuals should consult with their doctor if they feel that their blood oxygen levels are not within the normal range. It is essential to seek medical assistance to ensure proper diagnosis and treatment plans.


What are the symptoms of low/high oxygen levels?

Symptoms of low oxygen levels include shortness of breath, wheezing, confusion, blue tint on lips or nails, chest pain, and severe headache. Symptoms of high oxygen levels can include dizziness, nausea, increased heart rate and/or respiration rates, seizures or loss of consciousness.

Are there any lifestyle changes I can make to help raise my blood oxygen level?

Yes, lifestyle changes such as quitting smoking, reducing stress levels, and exercising regularly can all help to raise your blood oxygen level. Additionally, incorporating recommended supplements into your daily routine can offer a natural boost.
