Sleep apnea is a common sleep disorder that can be treated with continuous positive airway pressure (CPAP) machines. These machines require a prescription from a doctor, who will assess your individual needs and rule out any safety issues before prescribing CPAP therapy. Obstructive sleep apnea (OSA) is the most common form of sleep apnea, characterised by repeated episodes of partial or total upper airway obstruction, resulting in arousals from sleep and changes in oxygen levels. While CPAP machines are considered the first-line treatment for moderate to severe sleep apnea, treatment recommendations for mild sleep apnea are less clear-cut and should be determined based on the severity of symptoms and other health problems.

What You'll Learn
A prescription is required for a CPAP machine
Sleep apnea is one of the most common sleep disorders in the United States. While lifestyle changes can help improve your sleep apnea symptoms in the long run, many doctors turn to continuous positive airway pressure (CPAP) therapy as a treatment option.
If you’re thinking about trying a CPAP machine, you’ll need a formal prescription from your doctor before you can buy one. Although CPAP therapy is relatively safe and one of the most effective ways to treat the symptoms of sleep apnea, you’ll need to make a trip to the doctor’s office first.
In 2018, the FDA reclassified CPAP machines from Class III to Class II medical devices. With this change, officials at the FDA hoped to break down regulatory hurdles, encourage product innovation, and improve access for patients. But even with the new designation, you’ll still need a prescription from your doctor before you can buy a CPAP machine and begin CPAP therapy.
A prescription requirement ensures that your CPAP therapy will be safe and customised to your needs. When you consult with your doctor before starting CPAP treatment, you’ll have a better understanding of your sleep apnea diagnosis, the best type of unit for your needs, the right mask and delivery system, and the pressure setting for your symptoms. This oversight by a medical professional should improve the efficacy of your treatment. Without the guidance of your doctor, CPAP therapy may fail to improve your symptoms.
Additionally, a prescription allows you to receive reimbursement through your health insurance plan for your CPAP unit and other necessary CPAP accessories. Be wary of any retailers willing to sell you a CPAP without a prescription. The CPAP units they’re selling may not be FDA-approved.
Getting a CPAP prescription starts with recognising the symptoms of sleep apnea and making an appointment to see your doctor. Obstructive sleep apnea (OSA) is the most common type of sleep apnea. Symptoms include frequent and severe snoring, awakening with gasping or choking, nighttime restlessness, and sleepiness during the day. A less common form of sleep apnea is central sleep apnea (CSA). Because the airway isn’t physically blocked as in OSA, the symptoms of CSA can be harder to recognise.
Any medical doctor, including your primary care doctor, can write you a prescription for CPAP therapy. However, a sleep specialist will be able to administer a detailed sleep study. Self-reported symptoms are a useful starting point, but the results from a sleep study give a more detailed picture of your symptoms.

CPAP machines are used to treat sleep apnea
CPAP (continuous positive airway pressure) machines are a common treatment for sleep apnea. They use mild air pressure to keep your airways open while you sleep, allowing you to breathe and receive the oxygen you need. This is achieved by delivering continuous air through your mouth, nose, or both.
CPAP machines are comprised of a mask or device that fits over your nose or mouth, straps to position the mask, a tube that connects the mask to the machine's motor, and a motor that blows air into the tube. Some machines also have features like heated humidifiers and adjustable pressure settings.
CPAP machines are considered safe and effective in treating sleep apnea, and they are often recommended as a first-line treatment. They can significantly improve sleep quality and reduce the risk of associated health issues, such as high blood pressure, heart disease, and stroke.
To obtain a CPAP machine, you will need a formal prescription from your doctor. A sleep specialist can administer a detailed sleep study to determine the best course of treatment. The prescription ensures that your CPAP therapy is safe, effective, and tailored to your specific needs.

Sleep apnea can cause insomnia and excessive daytime sleepiness
Sleep apnea and insomnia often co-occur, and this combination is known as comorbid insomnia and sleep apnea (COMISA). COMISA is associated with an increased risk of medical and psychiatric conditions, including cardiometabolic conditions, mood disorders, and post-traumatic stress disorder. COMISA can also lead to worse daytime functioning, including excessive daytime sleepiness.
Sleep apnea is a sleep-related breathing disorder that affects an estimated 900 million adults worldwide. It is caused by the repetitive collapse of the upper airway, resulting in intermittent episodic hypoxia and impaired ventilation during sleep. One of the most common symptoms of sleep apnea is excessive daytime sleepiness, which can negatively impact daily functioning, cognition, mood, and overall well-being. Even with treatment for sleep apnea, such as continuous positive airway pressure (CPAP) therapy, a significant number of patients continue to experience excessive daytime sleepiness.
The pathophysiology of excessive daytime sleepiness in patients with sleep apnea is not entirely clear, but it is believed to be related to the intermittent hypoxia and sleep fragmentation caused by the disorder. Animal studies have shown that these conditions can lead to oxidative injury and changes in neurons and brain circuits connected to noradrenergic and dopaminergic neurotransmission in wake-promoting regions of the brain. Neuroimaging studies in humans have also found alterations in the brain's white and grey matter in patients with sleep apnea and excessive daytime sleepiness.
Treatment of excessive daytime sleepiness in patients with sleep apnea should begin with ruling out other potential causes, such as sleep deprivation, narcolepsy, or circadian rhythm disorders. Objective and self-reported assessments, such as the Maintenance of Wakefulness Test or the Epworth Sleepiness Scale, can be used to evaluate the severity of excessive daytime sleepiness. In some cases, wake-promoting pharmacotherapy may be recommended in addition to primary sleep apnea therapy. Modafinil, armodafinil, and solriamfetol are approved in the United States for the treatment of excessive daytime sleepiness in adults with sleep apnea. These medications work by inhibiting the reuptake of dopamine or both dopamine and norepinephrine, which are neurotransmitters involved in sleep-wake regulation.

CPAP machines pump pressurised air into the airways to keep them open
CPAP (continuous positive airway pressure) machines are a common treatment for sleep apnea. They deliver a continuous stream of pressurised air into the airways through a mask and tube, preventing the airways from collapsing and allowing the patient to breathe continuously while they sleep. The pressurised air is generated by a compressor (motor) and travels through an air filter into a flexible tube, which delivers the air into a mask sealed around the patient's nose or mouth. This process ensures that the airways remain open, and the lungs receive plenty of oxygen.
CPAP machines are considered safe and effective, significantly improving sleep quality and reducing the risk of various health issues such as heart disease and stroke. They are typically prescribed by a doctor, who will determine the optimal pressure setting and mask type for the patient's needs. The mask may cover just the nose, both the nose and mouth, or have prongs that fit into the nostrils. Straps are used to position the mask securely on the patient's face.
While CPAP machines are a popular treatment option, they may not work for everyone with sleep apnea. Some people may find the mask uncomfortable, claustrophobic, or embarrassing. Side effects of using a CPAP machine can include skin irritation, congestion, a runny nose, dry mouth, or nosebleeds. Additionally, CPAP machines can be cumbersome to travel with and require regular cleaning and maintenance.

CPAP treatment should be tailored by a healthcare professional
Sleep apnea is one of the most common sleep disorders in the United States. While it can be improved with lifestyle changes, many doctors use continuous positive airway pressure (CPAP) therapy as a treatment option. CPAP machines are one of the most common treatments for sleep apnea and are incredibly effective when used consistently.
CPAP machines can be purchased with a formal prescription from a doctor. A prescription is necessary to ensure that the treatment is safe and tailored to your needs. Before writing a prescription, a doctor will determine your diagnosis and recommend the best type of unit, mask, and delivery system for your needs. They will also advise on the right pressure setting and when to replace key accessories.
A prescription allows you to receive reimbursement through your health insurance plan for your CPAP unit and other necessary CPAP accessories. Medicare, for example, may cover a 3-month trial of CPAP therapy devices and accessories if you have been diagnosed with obstructive sleep apnea. After the trial period, Medicare may continue to cover CPAP devices and accessories if you meet specific conditions and your doctor documents that CPAP therapy is helping you.
It is important to consult with a healthcare professional before starting CPAP treatment to ensure the efficacy of your treatment. Without their guidance, CPAP therapy may fail to improve your symptoms.
