A continuous positive airway pressure machine, or CPAP, is a common therapy for sleep apnea. By supplying constant and steady air pressure, these machines help prevent problems that occur with intermittent breathing, such as cardiovascular problems, daytime fatigue, morning headaches and even death, according to MayoClinic.com. Finding a suitable machine may take some exploring, as several manufacturers produce different CPAPs with various features, according to the American Sleep Apnea Association.
Mask Features
Many mask styles are available, some featuring full face masks that cover most of the face and nose area. Elastic straps secure the mask in place and are worn behind the head. Some people prefer these broad masks, as they provide a steady fit for side-sleepers and those who move around a lot at night. Other masks, which cover less of the face, feature nasal pillows that fit under the nose. These versions are less bulky and may be more suitable for people who wear glasses at night, according to MayoClinic.com.
Humidifiers
Humidifiers are a convenient feature for those with a common CPAP complaint---dry, stuffy nose. A heated humidifier helps by adding moisture to dry air, eliminating nasal dryness and excess nasal mucous.
Ramp Feature
For people who find it difficult to endure forced air, MayoClinic.com reports that the ramp feature may help. This feature allows air pressure to increase, beginning gradually and increasing to the prescribed level over timed intervals. The rate at which the air pressure increases is also adjustable.
Data Tracking
Some CPAP machines allow patients and doctors to monitor breathing patterns by tracking activity at night. This feature records how often the machine is used and how often the patient suffered a lapse in breathing. The American Academy of Sleep Apnea reports that a doctor may want to download the information, which is stored on a thin card, to verify the sufficiency of the treatment and adjust the therapy as needed (see reference 2).
