The History of CPAP Machines

CPAP machines have been used for thetreatment of sleep apneasince 1981.

It was a remarkable discoveryand one met with initial skepticism.

It would take five years before the devices became more widely available commercially.

How Does A CPAP Work?

Modern CPAP machines work based on the same principles as the initial devices developed by Dr. Sullivan.

The pressures are now generated with smaller, quieter motors.

The constant flow of pressurized air creates a cushion along the upper airway.

Some have described it as a pneumatic (air) splint that keeps the throat from collapsing.

This prevents the soft palate, uvula, and tongue from shifting into the airway.

It reduces the vibration that creates the sound of snoring.

It may also relieve swelling within the nose and clear out mucus from along the airway.

By supporting the airway, breathing normalizes and sleep quality improves as fragmented sleep resolves.

Oxygen levels can be maintained.

Theserious consequences of sleep apneacan be averted.

These devices will also test lower pressures and adjust downward if possible.

Side Effects and Risks

Some inevitably worry about the consequences of seemingly artificial or unnatural CPAP therapy.

Fortunately, there are surprisingly few side effects.

Early communication with your healthcare team so they can help you troubleshoot problems is essential.

CPAP therapy does not worsen asthma or chronic obstructive pulmonary disease (COPD).

Rather than causing a stroke, therapy actually reduces the risk of having one.

It most often occurs secondary to stroke, congestive heart failure, or narcotic or opioid medication use.

It can also occur in response to CPAP therapy itself, in a condition calledcomplex sleep apnea.

In central sleep apnea, it is sometimes necessary to consider other therapy modalities.

This timed mode inflates the lungs to ensure a minimum number of breaths occur.

In addition, a more sophisticated level of treatment called adaptive (or auto) servo-ventilation can be used.

Fortunately, you dont need to know a lot abouthow your machine works.

However, many people have difficulty using it all night.

Talk to your healthcare provider about using a heated humidifier with your CPAP.

It depends on the person.

People who need higher air pressure to relieve their apnea may benefit from BiPAP instead of CPAP.
