When it comes to your blood oxygen level, a second look can never hurt.
Let’s be frank: if you’re currently living with a chronic lung disease like chronic obstructive pulmonary disease (COPD), pulmonary fibrosis (PF), or emphysema, the maintenance of your health and symptom expression is generally your top priority.
Often, this can mean a particular level of scrutiny in the foods you eat, the exercise you get, your exposure to cigarette smoke and other harmful airborne conditions, and the continual maintenance of your respiratory metrics, such as your PFT and blood oxygen levels.
Simply put, for those with lung disease, it’s not only incredibly important to monitor your health and make adjustments in your behavior when necessary, but for many, it’s a way of life.
Your blood oxygen level is one of the most important metrics to measure, as it clearly indicates how well your body is distributing oxygen (more on that in a moment).
Taking the time to determine your blood oxygen level and how it fits in with the national average can be a vital marker for the direction of your respiratory health.
With your health in mind, this article will break down the things you need to know about your Blood Oxygen Level: Is My Oxygen Level Normal?
What is Your Blood Oxygen Level?
In the most basic terms, your blood oxygen level is the amount of oxygen in your blood. Sounds simple, right? However, the complexities of this measurement come into play when trying to increase this amount by doing more than taking deeper breaths.
As you can imagine, the blood oxygen level is important for your general health. You may be hypoxemic if your blood oxygen is too low compared to a healthy adult’s average blood oxygen level.
As is the case of most people with COPD, oxygen levels are below normal, and hypoxemia can frequently occur over time. This means that your body has trouble nourishing your cells, tissues, and organs.
As your blood is the medium for getting oxygen (via red blood cells) throughout your body, poor circulation can produce the symptoms of chronic lung disease—namely shortness of breath.
Overall, this can reduce your quality of life, impair your skeletal muscle function, impair your exercise tolerance and increase your risk of death.
How is Your Blood Oxygen Level Measured?
A normal blood oxygen level typically ranges from 75 to 100 mm Hg. In the case of dangerously low blood oxygen, the level that requires supplemental oxygen is anything under 60.
The best way to monitor blood oxygen levels is through arterial blood gasses (ABGs); however, this can be difficult at home.
In place of using an ABG test, it’s more convenient to use a pulse oximeter, which measures oxygen saturation through a small clip on your finger. In the realm of oxygen saturation levels, normal is often considered anything between 95-100 percent.
Anything below 90 is usually considered low.
Therefore, if you are below this metric, you should consider asking your doctor for a prescription for supplemental oxygen.
What Does My Blood Oxygen Level Mean for My Health?
Your blood oxygen levels directly affect the expression of your symptoms. A low blood oxygen level can signify a lack of proper circulation or oxygen saturation within the body, which can ultimately result in a variety of conditions typically associated with chronic lung disease.
These may include:
- Confusion
- A sense of euphoria
- Restlessness
- Headaches
- Shortness of breath
- Rapid breathing
- Dizziness, lightheartedness and/or fainting spells
- Lack of coordination
- Rapid heart rate
- Elevated blood pressure
- Visual disturbances
- Bluish tint to lips, earlobes and/or nail beds
- Elevated red blood cell count or polycythemia
What Can I Do Moving Forward?
Understanding your blood oxygen levels is a key step in learning how to measure your health.
Whether it’s through measuring it yourself using a pulse oximeter or having it properly tested through an ABG test with your primary physician, knowing the basic metrics of your respiratory health is critical to making the changes necessary to improve it.
Although the most important step in taking control of your health is to quit smoking, a close second is to address your general health through diet and exercise.
These behavioral changes can greatly affect the pronouncement of symptoms for people with COPD, pulmonary fibrosis, and emphysema.
