There are different types of devices used to treat sleep apnea depending on the severity of the condition. Some of the main device types include:

Continuous Positive Airway Pressure (CPAP) Devices

CPAP devices are among the most common treatments for sleep apnea. A CPAP machine works by delivering a continuous stream of pressurized air through a mask worn over the nose, mouth, or both. The steady air pressure helps keep the airways open to prevent them from collapsing during sleep. CPAP devices are commonly prescribed for moderate to severe cases of obstructive sleep apnea. While highly effective, some people find the CPAP mask uncomfortable, especially when first using the device. With consistent use, however, most people adjust to sleeping with a CPAP.

Oral Appliances

Oral appliances that fit in the mouth like mouthguards are another noninvasive option. Dental appliances work by repositioning the lower jaw and tongue to open the airway. This helps prevent it from closing during sleep. Oral appliances tend to be better tolerated than CPAP for mild cases of sleep apnea or those who cannot adjust to mask therapy. However, their effectiveness varies more between individuals. Oral appliances must also be made by a dentist based on detailed molds of the teeth and jaw.

Surgical Options

Surgery is an option in some cases but generally reserved for those who do not respond well to other treatments. Surgical treatments aim to enlarge the airway, most commonly through procedures like uvulopalatopharyngoplasty (UPPP surgery). This removes extra tissue from the soft palate and uvula to open the airway. Implantable nerve stimulation devices are also being researched as another potential surgical treatment.

Emerging Treatment Options

Research into sleep apnea devices continues as researchers aim to develop more comfortable and effective options. Some emerging therapies under investigation include:

- Mandibular advancement devices: Similar to oral appliances but attached to braces or wires around the head to advance the lower jaw farther forward for a wider airway opening.

- Hypoglossal nerve stimulation: An implantable device placed under the skin that delivers mild pulses to stimulate the tongue muscle and keep the airway open during sleep.

- Respiratory neurostimulation: Uses an external stimulator near the neck rather than implants to stimulate nerves and muscles in the upper airway.

- Inspire upper airway stimulation: An implantable device surgically placed in the chest wall that monitors breathing and stimulates the hypoglossal nerve when signs of sleep apnea are detected.

Effectiveness of Sleep Apnea Treatments

When used consistently and properly, sleep apnea devices and treatments can significantly reduce or eliminate sleep disruptions from this breathing condition. However, their level of effectiveness can vary between individuals and based on the underlying severity of the sleep apnea. Here’s a closer look at how well different therapies typically work:

- CPAP is highly effective when used routinely, reducing apnea events by 80–100% in most cases of moderate to severe sleep apnea. However, adherence to nightly CPAP use can be challenging for some.

- Oral appliances are less effective than CPAP but may work well enough for mild cases, lowering apnea events by 40–80% on average. Success rates depend on proper fit and positioning of the device.

- Surgery such as UPPP can cure mild apnea but often only improves symptoms for moderate to severe cases, reducing events by 30–90%.

- Emerging nerve stimulation and neurostimulation devices show promise in large trials at reducing apnea by over 50% compared to a sham procedure, but long term usage is still being studied.

- Lifestyle changes like losing weight if overweight, avoiding alcohol, quitting smoking, etc. may help some cases but are usually not enough alone if sleep apnea is moderate or severe.

Selecting the Best Device

When choosing a sleep apnea devices, factors like the severity of symptoms, other health issues, lifestyle preferences, and insurance coverage should all be considered. It’s best to consult with a sleep specialist, known as a sleep physician, pulmonologist, or ENT doctor to determine the most appropriate therapy. A home sleep test or visit to a sleep lab may also be needed to accurately diagnose sleep apnea and its intensity. With the right device selected and proper use, sleep apnea can usually be successfully managed to restore restorative, uninterrupted sleep.
