What is a CPAP?

Continuous Positive Airway Pressure or CPAP therapy is a part of obstructive sleep apnea treatments, and allows a person to breathe without any difficulties during his sleep. In obstructive sleep apnea, air flow is obstructed in a person’s throat. A CPAP machine maintains a higher air pressure in the throat so that air can flow easily.

CPAP Equipment

A CPAP system comprises of a CPAP machine, a CPAP mask and a hose. The hose connects the machine and mask. A CPAP mask is of three types; the first type covers both the nose and throat, the second type covers only the nose and the third type is prongs which can be fixed inside the nose.

Reasons for Using CPAP Therapy

CPAP is one of the most effective sleep apnea treatments, and is usually the first one to be carried out. It can be used as a cure even if the person has severe sleep apnea. It can also be used for individuals suffering from coronary artery disease (CAD).


  • Daytime sleepiness in decreased.
  • Some people might experience a lower blood pressure.
  • Chances of cardiac problems are reduced.


  • A person might have nightmares or excessive dreaming in the beginning.
  • The nose may become dry and the throat may become sore.
  • Irritation may develop on the face.
  • A person may suffer from abdominal bloating

Other Similar Machines

There are many other devices similar to a CPAP machine such as an APAP machine or BIPAP machine. A CPAP machine maintains a continuous and constant pressure. An Automatic Positive Airway Pressure or APAP machine adjusts the pressure, and increases it only when a person is experiencing apnea. A Bi-level Positive Airway Pressure or BIPAP machine changes the pressure during inhalation and exhalation, and increases it during apnea.
