Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleeping. There are different types of sleep apnea, but the most common type is obstructive sleep apnea. This condition happens when the muscles relax during sleep allowing the soft tissue in the back of the throat to collapse and block the upper airway. This interrupts normal breathing. Some common symptoms of sleep apnea include loud snoring, waking up gasping or choking, waking up with a dry mouth, mood changes like depression or irritability, headaches, and excessive daytime sleepiness. Left untreated, sleep apnea can raise the risk for serious health issues like heart disease, stroke, diabetes and depression.
Types of Sleep Apnea Treatment Devices
The main types of devices used to treat sleep apnea are:
Continuous Positive Airway Pressure (CPAP) machines
CPAP machines are considered the gold standard non-surgical treatment for obstructive sleep apnea. A CPAP machine delivers a continuous flow of pressured air through a mask that is worn over the nose, mouth, or both during sleep. The steady stream of air keeps the airway passages open to prevent them from collapsing during inhalation. The specific pressure level is determined through a sleep study and varies per individual based on how severe their apnea episodes are. Compliance can be low due to discomfort from the mask, but new masks and humidifiers have made CPAP more tolerable for many.
Oral Appliances (Dental Devices)
Oral appliances are custom-fitted mouthpieces that are designed to adjust the position of the jaw and tongue with the goal of keeping the airway open during sleep. By repositioning the lower jaw and tongue slightly forward with elastics or other material, it creates space to keep obstructed areas from blocking breathing. Oral appliances may be an option for those with mild-moderate sleep apnea who can’t tolerate CPAP or refuse surgery. However, they require regular adjustments and dental visits for checkups.
Adaptive Servo Ventilation (ASV) Devices
ASV machines differ from traditional CPAP in that they actively monitor breathing and react with pressure changes if episodes are detected. The device senses when breathing stops or becomes shallow during sleep then gently increases pressure to help keep the airways open. ASV devices may benefit those with complex apnea such as Cheyne-Stokes breathing which involves longer pauses in breathing followed by deeper breaths.
Experimental and Emerging Devices
Research into new sleep apnea devices continues as scientists seek simpler, more comfortable and effective options. Some developing technologies include:
Implantable nerve stimulation devices: Experimental devices that send mild electrical pulses to stimulate nerves in the tongue or hypoglossal nerve to widen the airway during sleep.
Position detection systems: Sensors placed under the bed or mattress that detect body position and automatically adjust pressure if significant changes occur. This approach aims to reduce positional apnea.
Adaptive pressure relief (APR) CPAPs: Newer CPAP models use algorithms to detect upcoming exhalation and lower pressure briefly for improved expiration comfort compared to traditional fixed pressure CPAPs.
Tongue retention devices: Working similarly to oral appliances but target only the tongue with caps, straps or sleeves to keep it from falling back during sleep versus full denture-like mouthpieces.
Wireless home sleep apnea testing: At-home tests that transmit recorded breathing data via Bluetooth to clinicians for remote diagnosis and treatment planning without an in-lab polysomnogram.
As research continues, the goal is more patient preference in treatment choices and improved adherence to long-term management of this common sleep disorder affecting millions of people. Overall, established devices like CPAP when used as prescribed, can significantly reduce apnea events and restore restorative, uninterrupted sleep for better health and quality of life. Working closely with a sleep physician is important to finding the optimal solution.
Choosing the Right Device for You
When it’s time to choose a sleep apnea treatment device, the decision ultimately comes down to each individual’s own needs, preferences, and medical circumstances. Here are a few key factors to consider:
– Severity of apnea symptoms and risk factors – More severe cases often need CPAP at a minimum pressure while milder cases may do well with an oral appliance.
– Lifestyle and travel needs – CPAP and ASV require power sources limiting portability while oral appliances can be worn anywhere.
– Comfort and compliance priorities – CPAP and ASV have learning curves to acclimate but provide continuous treatment versus oral appliances requiring regular checkups and adjustments.
– Overall health – Conditions like obesity, heart disease or stroke history are weighed in determining the best approach.
– Insurance coverage – What devices are approved for coverage and reimbursement under specific plans.
– Device cost – Out of pocket costs vary significantly between CPAP, ASV, oral appliances, and emerging/experimental options.
An in-lab sleep study and follow up with a board-certified sleep specialist like a pulmonologist, otolaryngologist, or neurologist can determine the clinically appropriate treatment after factoring in diagnostic data and each patient’s profile and values. With today’s technology advancements, quality sleep within reach for many struggling with this prevalent disorder.
