COPD and Difficulty Breathing

What Is COPD?

COPD affects almost 16 million people Trusted Source Medline Plus MedlinePlus is an online health information resource for patients and their families and friends. View Source in the United States alone and is the third most common cause of death due to disease Trusted Source Merck Manual First published in 1899 as a small reference book for physicians and pharmacists, the Manual grew in size and scope to become one of the most widely used comprehensive medical resources for professionals and consumers. View Source . Smoking is the primary cause of COPD, with smoking history noted in up to 75% of COPD cases. Secondhand smoke, exposures to other pollutants, and more rarely, genetic conditions, can also increase the risk of developing COPD. COPD is a progressive disorder, which means that it gets worse over time, leading to shortness of breath, wheezing, chest tightness,  persistent cough,  and susceptibility to infections like pneumonia.

Can Breathing Difficulties From COPD Affect Sleep?

Those with COPD can experience oxygen desaturation (hypoxemia), or reduced oxygen levels in the blood. Severe COPD is often characterized by hypoxemia during the day, and worse daytime hypoxemia is correlated with more episodes of hypoxemia during sleep. Hypoxemia especially impacts rapid eye movement (REM) sleep, the stage of sleep where dreams occur.

When people with COPD experience sleep disruptions and don’t get enough sleep, they become sleep deprived.

Since wheezing and coughing can understandably make falling asleep very difficult, some COPD patients attempt to sleep while sitting upright in a chair. And, although sitting upright may relieve chest symptoms, it can also make falling asleep more difficult. As such, COPD patients may suffer from insomnia as they stay awake struggling to find a comfortable sleeping position.

Are Sleep Disorders Common in People with COPD?

COPD frequently coincides with obstructive sleep apnea (OSA), a condition characterized by gaps in breathing during sleep Trusted Source Merck Manual First published in 1899 as a small reference book for physicians and pharmacists, the Manual grew in size and scope to become one of the most widely used comprehensive medical resources for professionals and consumers. View Source . Sleep apnea causes frequent and sudden nighttime awakenings, as well as drops in blood oxygen levels that accompany spikes in carbon dioxide levels. Co-occurring COPD and OSA are known as “ overlap syndrome Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

How Do I Know If I Have a Sleep Disorder and COPD?

True to its name, overlap syndrome can be difficult to distinguish from isolated diagnoses of COPD or sleep-disordered breathing (SDB) alone, due to the number of symptoms shared between both disorders. These symptoms include reduced sleep quality, sudden awakenings featuring gasping and choking, headaches upon waking, and excessive daytime sleepiness. However, experts have identified certain features in COPD patients who suffer from SDB Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

The presence of any of the following symptoms may prompt doctors to evaluate  COPD patient’s sleeping difficulties with a sleep test:

• Snoring, gasping, or choking during the night
• Morning headache
• Excessive daytime sleepiness
• Obesity
• Reduced daytime oxygen saturation (hypoxemia)
• Increased daytime carbon dioxide saturation (hypercapnia)
• Pulmonary hypertension
• Right heart failure
• Polycythemia (high concentration of red blood cells in your blood)
• Opioid/hypnotic prescription use
• History of type 2 diabetes, heart failure, or stroke

Further, experts note that nighttime symptoms in COPD patients may be overlooked Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

Therefore, it is important for individuals with COPD to proactively report nighttime symptoms to their providers and ask if scheduling a sleep test is recommended.

How Do I Sleep With COPD?

Because COPD patients may have additional barriers to getting good sleep, practicing good sleep hygiene habits is especially important. Follow these tips to maximize your sleep quality:

• Avoid eating or drinking late in the day. You want to give your body time to digest and avoid waking up during the night to use the bathroom.
• Get moving! Make sure you get at least some moderate physical activity in.

• Quit smoking! Especially if you suffer from COPD, quitting is one of the best things you can do for your health.

Are There Treatments for Sleep Affected by COPD?

Yes, there are treatments available for COPD symptoms that negatively impact sleep or overlap with sleep-disordered breathing. Experts recommend the primary goals of therapy for overlap syndrome are to reduce hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) during sleep.

Continuous positive airway pressure (CPAP) Trusted Source Medline Plus MedlinePlus is an online health information resource for patients and their families and friends. View Source is a machine that helps keep airways open and prevent collapse during sleep by pumping in air. The CPAP machine is the first line of treatment for COPD patients with moderate to severe OSA. Additional oxygen therapy is indicated for those who experience severe daytime hypoxemia.

Medicines may also be used to treat chest symptoms and sleep symptoms in COPD patients. It is important to review all medications with your provider, as they will consider which medications may have a positive or negative impact on your sleep.
