This prevents the soft palate, uvula, and tongue from shifting into the airway. It reduces the vibration that creates the sound of snoring.

It may relieve swelling within the nose and clear out mucus from along the airway. By supporting the airway, breathing normalizes and sleep quality improves as fragmented sleep resolves. Oxygen levels can be maintained. The serious consequences of sleep apnea can be averted. Automatic CPAP machines vary slightly in that they can detect a collapse of the airway by measuring resistance and react by increasing the pressure as needed during the night to further resolve the sleep apnea.

These devices will also test lower pressures and adjust downward if possible. Fortunately, there are surprisingly few side effects. Still, in order to avoid side effects and ensure successful use, it is important that you have support when you first begin using CPAP.

Early communication with your healthcare team so they can help you troubleshoot problems is essential. Two of the most common problems associated with CPAP use are an ill-fitting mask and dry mouth. These can be alleviated with mask shape adjustments and humidification. Similarly, air leaks, challenges for bed partners, and air swallowing aerophagia are all commonplace and can be addressed to avoid discontinuation. Rather than causing a stroke, therapy actually reduces the risk of having one.

The nasal sinuses and inner ears are not typically impacted by the treatment, though case reports suggest it is possible for small amounts of pressure to be transduced across the tissues of the face. There is some evidence that an overly tight or restrictive mask could affect the growth of the mid-face in children, but treatment can be monitored and adjusted to avoid this.

It is important to review the special case of a related condition. Central sleep apnea is defined by pauses in breathing that are characterized by a lack of effort to breathe, rather than a collapse of the airway. It most often occurs secondary to stroke, congestive heart failure, or narcotic or opioid medication use.

Several tips can help you get used to your CPAP. Another part of getting used to the CPAP is remembering to communicate with your doctor or sleep technician.

When you first open your CPAP, write down the brand, model, and serial number. In the same place, jot down the phone number for your sleep technician, the CPAP manufacturer, and, if applicable, the local service provider who delivered your machine. These steps will simplify the process if you have any technical problems in the future. Establishing a routine for frequent cleaning allows you to avoid buildup of dirt, bacteria, or other contaminants.

Another tip is to think in advance about using your CPAP when traveling and to plan out the logistics of bringing the device with you. While these machines provide variable levels of pressure, their basic design is similar, and you can follow the same steps to use and get used to them.

While a CPAP dramatically improves sleep in most people with sleep apnea, there can be complications from using them. In most cases, these issues arise primarily in the first few nights, but some may persist over time.

If you experience these issues, contact your doctor or sleep technician. Changes in settings or other steps can usually resolve these side effects of CPAP therapy and make it easier for you to sleep well while using the device.

His research and clinical practice focuses on the entire myriad of sleep disorders.

Updated September 11, Mask styles can vary with different CPAP machines. Which type you wear depends in part on your breathing habits, how comfortable the mask is for you to wear, and the kind of sleep apnea disorder you have.

As with many types of treatments, there are benefits and drawbacks associated with the use of a CPAP machine. Here are a few of the known pros and cons. The benefits of using a CPAP machine are well-documented. These machines deliver a continuous supply of oxygen to your body as you sleep.

By doing so, they help prevent the brief breathing interruptions that are the hallmark of sleep apnea. Although a CPAP machine can help prevent breathing interruptions when you sleep, there are also drawbacks with this device. Some people stop using CPAP machines due to the side effects. CPAP machines treat sleep apnea by delivering a stream of oxygenated air into your airways through a mask and a tube. The pressurized air prevents your airways from collapsing, which allows you to breathe continuously while you sleep.
