While it is normal for oxygen levels to dip slightly during sleep, a significant drop can indicate an underlying health issue. Blood oxygen levels that fall below 88% during sleep are officially categorized as low. Drops in blood oxygen levels can be caused by sleep disorders, such as sleep apnea, or other medical conditions, including lung disease, neurological disorders, or heart disease. If you suspect that your oxygen levels are dropping during sleep, it is important to speak to a healthcare provider, who can recommend a sleep study or overnight oxygen monitoring.

|---|---|
| Normal oxygen levels during sleep | 95% to 100% |
| Oxygen levels considered low during sleep | Below 95% |
| Oxygen levels considered dangerously low | Below 88% |
| Oxygen levels considered severely abnormal | Below 80% |
| Oxygen levels considered mildly abnormal | 80% to 89% |
| Condition caused due to low oxygen levels | Sleep apnea |
| Other causes of low oxygen levels | Lung disease, neurological disorder, opioid painkillers, alcohol, sleeping pills, anxiety drugs, etc. |
| Symptoms of low oxygen levels | Shortness of breath, fatigue, dizziness, depression, etc. |

What You'll Learn
Sleep-related hypoxemia disorder
People with sleep-related hypoxemia disorder may experience disrupted sleep, such as insomnia, frequent awakenings, or night sweats. Shortness of breath causing sudden awakenings from sleep is also a typical symptom. Morning headaches are another common symptom, as the reduced oxygen levels can cause vascular changes in the brain. These symptoms can significantly impact an individual's daily life, making it essential to seek medical attention.
Effective treatment of sleep-related hypoxemia disorder can significantly improve sleep quality and overall health. Treatment options include both non-invasive and invasive methods, such as lifestyle adjustments, weight loss, anti-snore pillows, and, in some cases, surgical procedures to improve airflow and remove obstructive tissues.

Obstructive sleep apnea
People with OSA typically experience low oxygen levels during sleep due to gaps in their breathing caused by the blockage of the airway. This blockage is often a result of the throat muscles relaxing during sleep, preventing air from passing through the trachea (windpipe). OSA can also be caused or worsened by excess weight, especially around the neck and chest, which can compress the airway during sleep.
The reduced oxygen intake during OSA can lead to a condition called hypoxemia, where tissues in the body are deprived of the oxygen they need to function properly. This can cause symptoms such as fatigue, lightheadedness, shortness of breath, headaches, and dizziness. If left untreated, chronic low oxygen levels can lead to hypoxia, a medical emergency that increases the risk of critical illnesses such as heart disease, brain injury, and liver or organ damage.
OSA is typically diagnosed through an overnight sleep study, also known as a polysomnogram or sleep test. This study involves monitoring various body functions during sleep, including brain waves, heart activity, leg movements, eye activity, and breathing patterns. Based on the diagnosis and severity of OSA, treatment options may include lifestyle changes, such as weight loss or sleeping on one's side, and medical interventions, such as continuous positive airway pressure (CPAP) therapy, which provides a steady flow of pressurised air to maintain airway firmness and prevent collapse.
In summary, OSA is a serious sleep disorder that can lead to significant oxygen desaturation during sleep, resulting in adverse health consequences. Diagnosis and treatment of OSA are crucial to prevent potential long-term health risks associated with low oxygen levels.

Central sleep apnea
CSA often coexists with OSA, and patients can exhibit characteristics of both conditions. CSA is commonly associated with various medical conditions, particularly cardiovascular issues such as heart failure, atrial fibrillation, and ischemic stroke. It can also be caused by spinal cord injury, renal failure, and chronic opioid use, which predispose individuals to central apnea by transiently diminishing ventilatory output. CSA is more prevalent in older adults and the elderly population above 65 years of age.
The cyclical pattern of CSA during sleep involves periods of apnea or hypopnea alternating with hyperpnea. While there is a lack of effort during central events, the upper airway narrows or nearly collapses. Upper airway narrowing consistently occurs at the retropalatal level during induced hypocapnic central apnea and induced central hypopnea. Both hypoventilation and hyperventilation can contribute to central apneas, each acting through distinct pathophysiological pathways.
The treatment modalities for CSA aim to manage the condition and improve interprofessional collaboration. CSA can lead to abrupt awakenings, shortness of breath, insomnia, excessive daytime sleepiness, difficulty concentrating, and mood changes. While CSA is a serious condition, it is important to distinguish it from sleep-related hypoxemia, a separate disorder where blood oxygen levels drop to 88% or below for at least five minutes during sleep without hypoventilation or another sleep-related breathing disorder.

Lung conditions
While it is normal for oxygen levels to dip slightly during sleep, especially in the deeper stages, significant drops can signal an underlying issue. Typically, blood oxygen levels normally drop a small amount during sleep but not to low levels unless there is an underlying problem.
- Chronic Obstructive Pulmonary Disease (COPD): Damaged lungs struggle to maintain oxygen levels, and conditions like emphysema or chronic bronchitis can limit airflow and oxygen exchange, especially at night.
- Asthma: Poorly controlled asthma can cause nighttime airway constriction and reduced oxygen levels.
- Pneumonia or other respiratory infections: These can temporarily reduce lung function and oxygen intake.
- Obesity hypoventilation syndrome (OHS): Excess weight can affect how the lungs and chest muscles function during sleep.
If you suspect that your oxygen levels are dropping during sleep due to a lung condition, it is important to speak to a healthcare provider. They can assess your symptoms and medical history to determine if further testing or treatment is necessary.

Sleep-related breathing disorders
Obstructive sleep apnea (OSA) is the most common and serious sleep-related breathing disorder. It is characterised by recurrent episodes of partial or complete closure of the upper airway, resulting in disturbed breathing during sleep. OSA is associated with a decreased quality of life and significant medical comorbidities, including cardiovascular diseases such as coronary artery disease, stroke, and atrial fibrillation. Patients who report symptoms of snoring, witnessed apneas, or daytime sleepiness should be screened for sleep apnea.
Central sleep apnea (CSA) is a less common form of sleep apnea where the brain fails to signal the body to breathe consistently. CSA can be caused by opioid painkillers, alcohol, sleeping pills, and certain anxiety drugs, which are linked to lower blood oxygen levels and slowed breathing during sleep. Sleep-related hypoventilation disorders, including obesity hypoventilation syndrome (OHS), are characterised by inadequate breathing during sleep, resulting in elevated blood levels of carbon dioxide. These disorders are often tied to other health problems, such as lung conditions like chronic obstructive pulmonary disease (COPD) or pulmonary hypertension, or disorders affecting the nervous system.
Sleep-related hypoxemia disorder occurs when a person's blood oxygen saturation level drops during sleep, unrelated to changes in their breathing. This disorder is usually the result of another medical problem, such as lung disease or a neurological disorder. People with sleep-related hypoxemia may experience drops in oxygen saturation to 88% or below for at least five minutes during sleep, while levels below 92% may be a cause for concern. Snoring is also classified as a sleep-related breathing disorder if it occurs more than three nights per week and may be indicative of underlying obstructive sleep apnea. Chronic risk factors for snoring include obesity, alcohol use, sedative use, chronic nasal congestion, and sleeping position.
While it is normal for oxygen levels to dip slightly during sleep, significant drops can signal an underlying issue. Blood oxygen levels below 88% are considered dangerously low, and levels below 92% may be a cause for concern. If you think you may be experiencing sleep-related troubles related to breathing, it is important to talk to your doctor. They can assess your symptoms and medical history to determine if further testing is necessary, such as a sleep study or polysomnography, to identify if your blood oxygen levels are dropping during sleep.
