Fast facts about CPAP therapy
- CPAP stands for 'Continuous Positive Airway Pressure', which provides mild air pressure to a person's upper airway to keep it open
- An Australian physician, Dr Colin Sullivan, created teh CPAP machine in 1980
- You might consider CPAP treatment if you're diagnosed with obstructive sleep apnoea
If you’ve been diagnosed with obstructive sleep apnoea, your doctor or healthcare provider might’ve mentioned CPAP therapy being the gold standard of treatment.
We explore what CPAP therapy is, the history of CPAP and how it can help you with treating your obstructive sleep apnoea.
What does CPAP mean?
The word CPAP stands for Continuous Positive Airway Pressure. This refers to therapy that allows a person to breathe consistently and comfortably throughout sleep, by providing mild air pressure to a person's upper airway.
CPAP machines are most commonly used to treat sleep apnoea, a sleep disorder which occurs when your throat is partially or completely blocked while you sleep.
As your throat is blocked, this results in thousands of pauses in your breathing every night while you’re sleeping 1.
This puts strain on your body, including your heart. CPAP machines work to help avoid these pauses and stops in breathing.
By improving your breathing through CPAP therapy, you can get more restful sleep and ease the pressure that sleep apnoea puts on your body.
A short history of CPAP
Dr Colin Sullivan, an Australian physician, is credited with the invention of the CPAP machine in 1980.
It was created as a more effective and less invasive solution than the previous go-to treatment, a surgical procedure called a tracheotomy.
His invention has now become the ‘gold standard’ treatment for sleep apnoea 2.
His initial invention consisted of a breathing mask, hoses and a type of vacuum cleaner engine, which was designed to manage respiratory failure during sleep.
Since then, CPAP machines have evolved with improvements in technology and advances in research, resulting in the effective and versatile machines of today.
Some CPAP machines even come with humidifiers, which help add moisture into the air that is taken away from the CPAP machine, resulting in less dry mouth and more for patients.
How does CPAP therapy work?
The CPAP machine consists of two main components; a sleeping mask and a machine. The machine pushes air through a tube, to the mask and into your lungs as you sleep.
When it comes to the machine itself, there are fixed pressure, auto variable pressure, and travel machines.
CPAP masks come in various forms, including nasal, pillow, and full face masks. The varied selection of mask types means that you are able to find a solution that is comfortable and effective.
As with the varying forms of CPAP masks, these machine options allow for sleep specialists to decide on the most effective method of CPAP therapy for a particular person.
The most important part of CPAP therapy is sticking with it until you find a mask solution that works for you. Many people find CPAP therapy uncomfortable, don’t stick with it and their symptoms of sleep apnoea worsen3.
Should you consider CPAP therapy?
If you've been diagnosed with sleep apnoea, it's absolutely crucial to treat it properly as it can increase your risk of diabetes, stroke, memory lapses, and headaches.
CPAP is the most effective and most popular treatment for obstructive sleep apnoea.
