What is Continuous Positive Airway Pressure (CPAP)?

CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is considered the "gold standard" for treating obstructive sleep apnea (OSA) and has been available for 30 years. It refers to the pressurized air that is delivered through a special delivery system which utilizes a mask.

How does the CPAP device work?

There are three main components to a CPAP machine:

  • CPAP 

    The CPAP machine is basically a small box which has a motorized fan inside. This fan very quietly draws air from the room, gently pressurizes it, then delivers it at a setting specific to your needs.

    The air intake section of thA CPAP machine is a delivery system for sleep apnea treatment using pressurized air to keep the upper airway opene CPAP machine has a filter on it to eliminate the intake of dust, smoke, or other impurities in the air. This filter can be replaced as necessary.

    Another key part of the CPAP machine is the humidification chamber built into the box. This is where water is warmed to humidify the pressurized air before it is delivered. Warm, moist air soothes your nasal and upper airway passages and helps prevent swelling and discomfort that can sometimes occur while using the therapy. Although using humidification is optional, it brings relief for the majority of patients using CPAP therapy who live in dry or arid climates or who wake up with a dry mouth, nasal passages, or throat. The humidification chamber is pretty easy to keep clean and should last the lifetime of the machine itself.

  • HoseAttached to the CPAP machine is a hose which connects the box to the mask. This flexible, lightweight tubing is also typically heated to reduce any condensation that might collect inside it while the humidifier is in use. The hose is long enougharound 6 feet—to give you full movement during sleep. Hoses can wear out over time and should be replaced as necessary.

  • MaskThat leaves the CPAP mask. It is often said that the success of CPAP therapy often rests on how comfortable and well fitting the mask is. As we discussed recently in our blog, CPAP masks come in a variety of shapes and sizes to suit the vast array of facial landscapes. Masks wear out over time and should be replaced on a regular schedule.

CPAP Benefits

Once CPAP therapy begins patients will begin to see the positive benefits in just a few weeks. For CPAP therapy to deliver best results, patients need to use their CPAP device regularly. Some of the signs that CPAP therapy is working are:

  • waking up refreshed with cpapElimination of snoring and nightly obstructive apnea events.

  • Improved quality of sleep.

  • Increased ability to focus/concentrate during the day.

  • Considerable reduction of daytime drowsiness.

  • Lower overall blood pressure (both at night and during the day).

  • Prevention or reversal of serious medical conditions such as heart diseases and stroke.
