Oxygen therapy is a common treatment for people with breathing problems, such as sleep apnea, asthma, obesity, heart disease, and lung disease. It involves using an oxygen concentrator or liquid oxygen tank to increase the oxygen saturation in the blood, which can improve quality of life, exercise tolerance, and survival. While oxygen therapy is typically used during the day, some people may also need it at night while they sleep. This is because oxygen saturation usually drops during sleep, and if it falls below 88%, it can lead to health complications such as brain damage, loss of consciousness, coma, or sudden death. Therefore, it is essential to consult a doctor to determine if you need supplemental oxygen and, if so, the correct dosage and type of equipment.
| Characteristics | Values |
|---|---|
| When to use oxygen while sleeping | If your waking oxygen saturation is greater than 94%, it is unlikely that your saturation during sleep will fall below 88%. If your blood oxygen level is below 94% during the day, you may need oxygen therapy for a while during the day, as well as all night long while you sleep. |
| Who needs oxygen while sleeping | People with sleep apnea, asthma, obesity, heart disease, or lung disease may not get enough oxygen during sleep. |
| Benefits of using oxygen while sleeping | Improved health and well-being, reduced risk of developing health problems triggered by low oxygen levels, better sleep, improved mood, increased alertness, and ability to do more activities. |
| Precautions | You need to get your doctor's approval before using an oxygen sleeping machine. Oxygen settings of 4 liters per minute or above can cause dryness and bleeding of the nose lining. |
| Types of oxygen therapy equipment | Standard oxygen sleeping machine, portable oxygen concentrator, liquid oxygen tank, compressed oxygen gas tank, and continuous positive airway pressure (CPAP) therapy. |

What You'll Learn
Oxygen therapy equipment options
Oxygen therapy is often required when a person's blood oxygen level falls below 94% while they are awake. Oxygen therapy equipment options include:
Oxygen Concentrator
A home oxygen concentrator is a type of oxygen delivery device that draws in air from the surroundings, removes nitrogen and other gases, and delivers purified oxygen to the user. It needs to be plugged into an electrical outlet to operate. A portable oxygen concentrator (POC) is a smaller, plastic variant that can be powered by plugging into an outlet or using rechargeable batteries. POCs can be carried in backpacks or slung over the shoulder.
Compressed Oxygen Tank
Compressed oxygen tanks are a common oxygen delivery device. They come in different sizes, with smaller tanks containing less oxygen. The size of the tank is prescribed by a doctor based on how much oxygen is needed. Some portable tanks are refillable by the patient, while others need to be returned to the oxygen supply company for a refill. Gauges on the tank can be used to adjust the oxygen flow rate, which should be determined by a doctor.
Liquid Oxygen Tank
Liquid oxygen is a type of oxygen delivery where oxygen is compressed and cooled to a very low temperature. It usually consists of a stationary storage unit and a portable container. Liquid oxygen systems do not require electricity to run. However, they can cause frostbite burns to the skin if not handled carefully.
CPAP Device
A CPAP device is used to prevent airways from collapsing. It requires a prescription and is set up by a respiratory therapist. In a home setting, an adapter is added so that oxygen is attached using a flow meter with preprogrammed settings. It is important to keep the mask and tubing clean to prevent infection.
Pulse Oximeter
A pulse oximeter is a portable device used to obtain a patient's oxygen saturation level. It is an electronic device that noninvasively measures the oxygen saturation of hemoglobin in a patient's red blood cells. It can be used at the bedside or in a clinic.
Nasal Cannula
A nasal cannula is an oxygen delivery accessory that consists of tubing connected to two short prongs that are inserted into the patient's nose. It is the most common type of oxygen equipment and is used for short- and long-term therapy. Flow rates can range from 1 to 6 liters per minute.

Pre-existing conditions and oxygen
If you have pre-existing conditions, such as asthma, sleep apnea, obesity, heart disease, COPD, sickle cell disease, or pneumonia, you may not get enough oxygen during sleep. Low oxygen levels can lead to further complications of these pre-existing conditions, as well as the development of new health issues. For example, low oxygen levels can cause potential brain damage due to depressed brain function, and in the worst cases, can lead to loss of consciousness, coma, or sudden death.
People with pre-existing conditions, such as sleep-related breathing disorders, heart disease, or lung disorders, should be cautious when taking opioid painkillers, alcohol, sleeping pills, and certain anxiety drugs, as these have been linked to lower blood oxygen levels and slowed breathing during sleep.
If you have any concerns about your oxygen levels during sleep, you should consult a doctor. They may recommend oxygen saturation monitoring during daily activities to ensure you are receiving the right amount of oxygen. Your doctor may also order an overnight oximetry test to measure your oxygen saturation levels while you sleep. If you require supplemental oxygen, your doctor will prescribe it, including the flow rate, type of flow, and the time of day when oxygen is required.
It is important to follow your doctor's prescription for oxygen therapy. If you experience headaches, confusion, or increased sleepiness after starting oxygen therapy, you may be receiving too much oxygen. Oxygen settings of 4 litres per minute or above can cause dryness and bleeding of the nose lining, so a humidifier attached to your oxygen equipment or certain ointments can help prevent or treat this.
Supplemental oxygen can improve your quality of life, exercise tolerance, and survival. It can also relieve symptoms such as shortness of breath, fatigue, dizziness, and depression. You may feel more alert, sleep better, and be in a better mood.

Oxygen levels and sleep quality
Low oxygen levels during sleep can result in several adverse health effects, including erratic heart rate, shortness of breath, and poor sleep quality. It can also cause a choking sensation, leading to sudden awakenings throughout the night. During the day, individuals experiencing low oxygen saturation during sleep may feel fatigued, irritable, and moody. They may also experience memory loss, difficulty concentrating, and daytime sleepiness.
Certain medical conditions, such as asthma, sleep apnea, obesity, and heart disease, can increase the risk of low oxygen levels during sleep. People with these conditions may require supplemental oxygen to maintain healthy oxygen saturation levels. Obstructive Sleep Apnea (OSA), for example, can cause oxygen saturation levels to drop due to hypoxia, and a doctor may recommend supplemental oxygen therapy in addition to CPAP therapy.
Supplemental oxygen therapy can significantly improve sleep quality and overall health for those with low oxygen saturation levels. It can help alleviate symptoms such as shortness of breath, fatigue, dizziness, and depression. It can also improve alertness, mood, and energy levels. However, it is important to consult a healthcare provider to determine the need for supplemental oxygen and the appropriate dosage, as excessive oxygen intake can lead to side effects such as headaches, confusion, and increased sleepiness.
There are various options for oxygen therapy equipment, including standard oxygen machines, portable oxygen concentrators, liquid oxygen tanks, and compressed oxygen gas tanks. Each option has its advantages and considerations, such as portability and maintenance requirements. It is essential to follow safety precautions and work with a healthcare provider to choose the most suitable equipment and dosage for an individual's specific needs.

Oxygen saturation and monitoring
Oxygen saturation measures the percentage of a person's red blood cells that carry oxygen, otherwise known as oxygen saturation. Doctors and nurses usually measure blood oxygen levels using a pulse oximeter.
Pulse oximetry is a commonly used screening test that evaluates blood oxygen levels. The test involves applying a plastic clip called an oximeter over the end of your finger. The test can be done at home and is useful for evaluating whether you have a sleep disorder, like sleep apnea.
Sleep apnea and respiratory disorders can impact oxygen saturation. If your blood oxygen level is above 94% while you're awake, you might not need oxygen therapy during the day. If your blood oxygen level is below 94% during the day, you may need oxygen therapy for a while during the day and all night long while you sleep.
If you experience headaches, confusion, or increased sleepiness after starting to use supplemental oxygen, you might be getting too much. Oxygen settings of 4 liters per minute or above can cause dryness and bleeding of the nose lining.
It is important to discuss oxygen therapy with your healthcare provider. They can assess your specific needs and adjust your oxygen therapy accordingly. They might recommend oxygen saturation monitoring during daily activities to ensure you are receiving the right amount of oxygen.
