Fixed CPAP

Fixed CPAP machines are devices used to treat obstructive sleep apnea by delivering a constant air pressure throughout the night. This pressure is determined during a sleep study or titration and remains stable during therapy.

Fixed CPAP machines are a reliable and well-established solution when pressure requirements are consistent, ensuring that the airways remain open during sleep.

What is a fixed CPAP machine used for?

A fixed CPAP machine is used to prevent upper airway obstruction in people with sleep apnea. By delivering continuous and stable pressure, it helps prevent apneas, hypopneas and frequent nighttime awakenings.

This therapy improves sleep quality, reduces daytime sleepiness and helps lower cardiovascular risks associated with untreated sleep apnea.

How does a fixed CPAP machine work?

A fixed CPAP machine draws in ambient air, filters it and delivers it under pressure through a tube connected to a mask worn during sleep. Unlike Auto CPAP devices, the pressure remains the same from the beginning to the end of the night.

The pressure level is set according to a precise value prescribed by a healthcare professional based on the patient’s needs.

What are the benefits of a fixed CPAP?

• Stable and constant pressure, ideal when pressure needs do not vary.
• Proven reliability for the treatment of obstructive sleep apnea.
• Simple operation with fewer complex settings.
• Often more affordable than automatic CPAP models.

How to choose a fixed CPAP machine?

Choosing a fixed CPAP machine depends on several key factors:

• the prescribed pressure level following a sleep study,
• comfort and noise level during nightly use,
• compatibility with CPAP masks (nasal, full face or nasal pillow),
• humidifier options to reduce dryness and irritation,
• comfort features such as ramp and exhalation pressure relief.

A medical prescription is essential to ensure that the pressure setting is appropriate and effective.

Frequently asked questions about fixed CPAP machines

What is the difference between fixed CPAP and Auto CPAP?
Fixed CPAP delivers a constant pressure throughout the night, while Auto CPAP automatically adjusts pressure based on breathing patterns.

Is fixed CPAP effective for treating sleep apnea?
Yes. Fixed CPAP is highly effective when pressure requirements remain stable during sleep.

Do I need a prescription to buy a fixed CPAP?
Yes. A medical prescription is generally required to purchase and set up a fixed CPAP machine for sleep apnea therapy.
