How Does A BiPAP Machine Work?

by Amanda Johnson on May 30, 2010

The BiPAP machine is the direct descendant of the Continuous Positive Airway Pressure machine created in the 1980s. This machine was generally used for people who were diagnosed with having sleep apnea. It was and is a machine that helps people get more air into their lungs while they are sleeping. BiPAP stands for Bi level Positive Airway Pressure.

The machine can be set with preset pressures for inhalation and exhalation. It will monitor how many times a person takes a breath. When the person appears to stop breathing when they should not be the machine will kick into action. The machine has the ability to count all the breaths the person takes every minute.

The BiPAP machine closely monitors the person who is sleeping and when a person misses even one breath the BiPAP will increase the air pressure right away. By doing this it forces the person to actually take a breath.

When the sleeping person has taken a breath on their own the machine will then decrease the amount of pressure so that it will be easier for the person to exhale. Everyone has their own breathing pattern, which can change even nightly. The machine has been programmed to easily adjust to the person and their breathing by adjusting the pressure. This procedure also helps a person to have a deeper nights’ sleep.

The BiPAP machine runs very quietly. It also is very compact and will easily sit on the nightstand of the person sleeping. These machines can also come with humidifiers that can be either heated or not heated and will work along with the air pressure and the cycles the machine goes through. The patient can also choose to use a nasal pillow mask or a mask that covers most of the face. A person can get them with or without support for their chin as well.

Those who think they might have sleep apnea should make an appointment to see their doctor. When a patient goes to their doctor thinking they might have sleep apnea, the doctor will first give the patient a couple of tests to see if they qualify for a sleep study. The first test would be a respiratory test that calculates just how large a capacity their lungs have. The second test is called the Forced Vital Capacity test. This will tell the doctor just how deep of a breath a person can take. He or she will decide whether or not they need to enroll in a sleep study. After taking the sleep study, if it is discovered that they do have sleep apnea then the doctor will prescribe a BiPAP machine.
