How does a CPAP machine work?

Were you diagnosed with obstructive sleep apnea (OSA) and now every night you sleep with a CPAP machine (continuous positive airway pressure machine)? The CPAP helps control your breathing, giving you an undisturbed cpapnight of rest. The CPAP machine provides pressurized air to your upper airway while sleeping to keep your airway open.

The apparatus generally consists of an air compressor and either a nasal or facial mask. To help keep the mask in place while you sleep, it comes with a strap. The strap not only goes around your head but also under your chin to keep the mouth closed letting the majority of the breathing to be done through the nose. A tube then connects the mask to the machine. There is a motor that blows air into the tube and through your mask into your airway. Some CPAP machines monitor your breathing and apply pressurized air only when you need it.

The CPAP machine has a small tank for water and a filter that are designed to remove impurities and increase the humidity level in the air. This helps keep the patients from developing nosebleeds, along with dry mouth and throats.

According to the National Sleep Foundation 50% percent of the 18 million people with sleep apnea regularly use their CPAP machines. Even though the machine is quiet, some patients feel claustrophobic with the mask. Remember if you want your CPAP machine to be effective, you must wear it 6-8 hours while sleeping.

Even though CPAP machines are not prescribed to treat snoring, they help eliminate snoring in addition to sleep apnea.

If you have any questions about your CPAP machine or concerning sleep apnea contact your sleep specialist.
