FAQs
Your blood oxygen during sleep should never drop below 92%. These are signs you should be looking out for which may indicate that you're not getting enough oxygen while you're asleep. Waking up with a headache: Lack of oxygen can trigger headaches, especially in the morning.
What are the symptoms of not getting enough oxygen while sleeping? ›
The most common symptoms of obstructive and central sleep apneas include:
- Loud snoring.
- Episodes in which you stop breathing during sleep — which would be reported by another person.
- Gasping for air during sleep.
- Awakening with a dry mouth.
- Morning headache.
- Difficulty staying asleep, known as insomnia.
Sleep Apnea is really about oxygen! During apnea events the body is denied oxygen. Normal blood oxygenation is at 90%- 95%. An apnea event can drive that level into the 80's% or even 70's%.

How to Increase Oxygen Levels While Sleeping
- Pay Attention to Your Eating Habits.
- Sleep On Your Side.
- Deal With Nasal Congestion.
- Provide Supplemental Oxygen.
Oxygen saturation levels below 90% are considered harmful. Usually, treatment is directed at correcting the apnea, which will in turn prevent hypoxemia. Unfortunately, many patients fail or are not candidates for nasal continuous positive airway pressure (CPAP) or surgical correction of their OSA.
What are four signs of oxygen deficiency? ›
Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin. Many chronic heart and lung conditions can put you at risk for hypoxia.
Will you wake up if your oxygen level is low? ›
Waking up frequently during the night: Low oxygen levels can wake you up, disrupting your sleep cycle. You may not even remember waking up. Snoring or sleep apnea: Snoring or obstructive sleep apnea makes it more difficult to get oxygen as your breathing is impaired during sleep.
Is oxygen better than CPAP for sleep apnea? ›
Oxygen concentrators and CPAP machines serve different functions. An oxygen concentrator is used to treat respiratory conditions that cause low oxygen levels in the blood. A CPAP machine is used to keep the airway open during sleep and prevent the breathing interruptions that occur as a result of sleep apnea.
What should your oxygen level be when lying down? ›
Normal oxygen levels during sleep range from 96% to 100%. Sleep apnea and respiratory disorders can impact oxygen saturation. Monitor and address any chest pain, shortness of breath, and concerning symptoms.
Do oxygen levels drop during REM sleep? ›
During REM sleep, breathing is irregular, with shallow amplitude, and low frequency. Hypoxemia, often due to hypoventilation, is often observed in comparison with NREM sleep. That is, during REM sleep, the oxygen saturation is generally lower than that during NREM sleep.
Drink plenty of water: Well-hydrated lungs are more efficient at dispersing oxygen into your bloodstream. The average daily water intake for “men is about 15.5 cups and for women, about 11.5 cups.”
What is the best position to increase oxygen levels? ›
Although oxygen saturation values were within the normal range in the five different body positions, post hoc analysis showed that the best oxygenation was in the 'sitting upright' position while the lowest oxygenation was in the supine position.
What are the symptoms of lack of oxygen to the brain? ›
What are cerebral hypoxia symptoms?
- Ataxia (not being able to control movement).
- Dizziness or feeling lightheaded.
- Feeling euphoric for no known reason.
- Tachypnea (rapid shallow breathing).
- A sensation of numbness and tingling.
- Trouble concentrating.
Some common signs in people with lack of oxygen when sleeping are: Snoring: This is a common sign of people with lack of oxygen when sleeping. In addition, accompanied by snoring, snoring, shortness of breath, and choking sound.
What oxygen level indicates sleep apnea? ›
When the percentage of oxygen saturation falls below 94%, that is called a desaturation. If the total number of desaturations divided by the total time is 5 or more desaturations per hour, then that is considered mild sleep apnea.
What is the lowest oxygen level you can live with? ›
When should I call my doctor? If you're using an oximeter at home and your oxygen saturation level is 92% or lower, call your healthcare provider. If it's at 88% or lower, get to the nearest emergency room as soon as possible.
How will I feel if my oxygen is low? ›
The brain is the body organ most sensitive to lack of oxygen. Low oxygen concentrations can include giddiness, mental confusion, loss of judgment, loss of coordination, weakness, nausea, fainting, loss of consciousness, and death.
What are silent hypoxia symptoms? ›
Possible signs of silent hypoxia include mild COVID symptoms for a couple of days before a dramatic tightening of the chest, pain when trying to take deep breaths, profuse sweating for no reason, and blue lips or a change of color in the skin, ranging from cherry red to blue.
How can I raise my oxygen level quickly? ›
Some ways include: Open windows or get outside to breathe fresh air. Something as simple as opening your windows or going for a short walk increases the amount of oxygen that your body brings in, which increases overall blood oxygen level. It also has benefits like improved digestion and more energy.
What happens when your brain doesn t get enough oxygen when you sleep? ›
The body's response to lack of oxygen to the brain
Insomnia: People with cerebral hypoxia often experience sleep problems such as restless sleep, frequent nightmares, sleep or wakefulness is also difficult to control, waking up in the middle of the night or in the morning can't fall asleep.
