Understanding normal oxygen levels
The average person takes about 20,000 breaths a day. Keeping normal oxygen levels is a finely-tuned science.
Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has dropped below average, 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. Levels above 90 percent are not considered low, so you probably are worrying. A problem with any of these factors — for example, high altitude, asthma or heart disease — might result in hypoxemia, particularly under more extreme conditions, such as exercise or illness. When your blood oxygen falls below a certain level, you might experience shortness of. Exercise frequently. Unfortunately, many people lead a sedentary lifestyle nowadays, which means.
“We’ve got to get oxygen from the atmosphere into our lungs; we’ve got to get the oxygen from our lungs into our bloodstream, and then we’ve got to get the blood to our cells, and our cells have to take out that oxygen.”

How do I check my oxygen level at home?
When you are at home and don’t have all of the electronic devices and laboratory access typically found in a hospital, there are two ways to check your oxygen level:
- a portable pulse oximeter and
- assessing physical signs and symptoms.
If you regularly use oxygen at home, it is a good idea to get a portable finger pulse oximeter. This device is similar to the electronic pulse oximeters used in medical facilities.
When you need to assess your oxygen level (or oxygen saturation) at home, this device will give you a number based on a range from 70%–100% and will also display your current heart rate. This data can be used to help you make important decisions during an emergency.
Normal oxygen saturation levels are 95% – 100%, although many patients that require oxygen at home may be at a lower baseline, ranging from 85%–95%.
If you do not have a portable finger pulse oximeter in your home, you can also learn how to assess signs and symptoms of low oxygen levels.
If you are the patient using oxygen, it is a good idea to learn these signs and symptoms yourself, but you will also want your family members or anyone who lives with you to be aware of these signs in case of an emergency.
Oxygen level in the human body
Audioquest dragonfly software for mac free download. Two classic signs of a low oxygen level are a rapid heart rate and a fast breathing rate. A normal heart rate is 60–100 beats per minute and a normal breathing rate is 12–20 breaths per minute. However, under conditions of low oxygen, your body responds by increasing your heart rate and speeding up your breathing rate.
How to take a pulse oximeter reading
- Follow your health care provider’s recommendations about when and how often to check your oxygen levels.
- Write down your oxygen levels with the date and time of the reading so you can easily track changes and report these to your health care provider.
- Be aware that multiple factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish.
- To get the best reading from a pulse oximeter:
- When placing the oximeter on your finger, make sure your hand is warm, relaxed, and held below the level of the heart.
- Remove any fingernail polish on that finger.
- Sit still and do not move the part of your body where the pulse oximeter is located.
- Wait a few seconds until the reading stops changing and displays one steady number.
- Follow the manufacturer’s instructions for use.
Respiratory therapists frequently teach their patients specialized breathing techniques. According to the American Lung Association, “If practiced regularly, breathing exercises can help rid the lungs of accumulated stale air, increase oxygen levels and get the diaphragm to return to its job of helping you breathe.”

Pulse Oximeters: Answering Your Frequently Asked Questions
Blood oxygen levels during sleep should be at a 95 percent saturation, which is considered normal, according to the American Sleep Apnea Association (AASM).
It is normal for blood oxygen levels to decrease during sleep. All body systems have altered basal function during your sleep, including breathing. You don’t breathe as deeply when you are sleeping, and not all your lung spaces function at full capacity. Because of this effect of sleep on breathing, it is normal for your sleep oxygen level to decrease below awake levels. Tests that show a waking oxygen level at or above 94 percent typically indicate a sleep oxygen level of at or above 88 percent.
Normal Human Body Oxygen Level
However, when it persistently drops below maintenance levels, health problems can develop. In addition, certain medical conditions can lead to low oxygen while you are asleep.
Medical Disorders
According to the Mayo Clinic, certain medical problems, especially of the cardiovascular and respiratory systems, can lead to blood oxygen below normal levels. The effects of these conditions can worsen while you are sleeping. The most common disorders include:
Diseases of the lungs:
Sim card programming software, free download mac. Several lung diseases can narrow or block lung air spaces, inflame or scar lung tissue, and can also interfere with normal breathing patterns. These lung diseases include:
- Chronic obstructive pulmonary disease (COPD), such as emphysema and chronic bronchitis
- Asthma
- Cystic fibrosis, a genetic disease that causes a build of mucus in the lungs
- Pneumonia and other lung infections
- Smoking and lung cancer
Heart diseases:
Disorders of the heart, which can interfere with blood flow, blood oxygen level, and oxygen supply to tissues include:
- Coronary heart disease, a build-up of plaques in the arteries of the heart
- Congestive heart failure with leakage of fluid into lung tissue
- Congenital heart disease, a developmental defect in the structure of the heart
Anemia:
The decrease in hemoglobin (Hgb) with anemia lowers the ability of your red blood cells to absorb oxygen from your lungs and carry it to your tissues. Abnormal Hgb, such as with sickle cell anemia, causes the same problem.
Obesity:
This a cause of sleep apnea where the throat becomes obstructed during sleep and interferes with breathing. Obesity also causes obesity hypoventilation syndrome (OHS), with diminished deep breathing and oxygen intake.
Drugs:
Chronic use of prescription or illegal opioids, sedatives, and recreational or other illegal drugs can depress the brain’s breathing center and therefore slow down your breathing and oxygen intake.
Alcohol:
Abuse of alcohol, especially at bedtime and mixed with drugs, can interfere with normal breathing and sufficient oxygen intake.
Health Consequences
A normal blood oxygen level is vital for normal tissue and cellular function. Therefore, low blood oxygen affects the function of every tissue in the body. A chronic problem of low oxygen levels while sleeping can increase the risk for several health consequences including:
- Sleep disorders, such as bouts of insomnia
- Poor sleep quality, such as restless sleep with several awakenings
- High blood pressure
- Cardiovascular disease including heart failure
- Cardiac arrhythmia and a risk for sudden death
- Type 2 diabetes
- Depressed brain function and possible brain damage
- Risk for loss of consciousness, coma, and death
If you think your oxygen level falls below normal while you are sleeping, consult with your doctor. He might suggest a sleep study as part of your evaluation. During an overnight stay in a sleep center, a technician monitors your breathing and other signs, as well as your blood O2 sat with a pulse oximeter during sleep.
