ResMed | CPAP Machines, Masks & Accessories

A CPAP machine delivers a continuous stream of pressurised air through a mask to keep your airway open during sleep. This helps reduce breathing pauses caused by obstructive sleep apnoea and can improve sleep quality, oxygenation and daytime alertness.

CPAP delivers a fixed pressure throughout the night.

Auto CPAP (APAP) automatically adjusts pressure based on your breathing patterns, sleep position and airway resistance.

Auto CPAP machines are often chosen for comfort because they can deliver lower pressure when you do not need as much support and increase pressure only when required.

BiLevel machines deliver two pressures, a higher pressure when you inhale and a lower pressure when you exhale. They are commonly used when higher pressures are needed, when exhalation feels difficult on CPAP, or when more complex breathing support is indicated.

Travel CPAP machines are compact, lightweight devices designed for portability. They suit frequent travellers who want dependable therapy on holidays, business trips and flights. Many are aircraft approved and compatible with external batteries for use when mains power is limited.

Modern CPAP machines are designed to be quiet and unobtrusive. In most bedrooms, the sound is comparable to gentle background noise. If you notice increased noise over time, changing filters and checking the tubing connections often helps.

Many CPAP and Auto CPAP machines include an integrated humidifier, while others offer a humidifier as an optional add-on. Humidification can reduce dryness, sore throat, nasal irritation and congestion, especially in heated rooms or drier climates.

Yes. CPAP devices are generally accepted as medical equipment for carry-on. If you plan to use CPAP during a flight, check your airline’s requirements and consider an aircraft-approved CPAP battery for longer journeys.

CPAP machines are medical devices typically supplied following diagnosis and a recommended pressure range. Requirements can vary depending on location and supplier policies. If you are unsure which machine you need, contact CPAP Supply UK and we will help you choose the correct option.

Most CPAP machines last around 5 to 7 years with appropriate care. Keeping filters clean, using the correct power supply, and storing the device properly can help maintain performance and extend lifespan.

Choosing the right machine depends on your therapy needs and lifestyle. Auto CPAP suits most users, BiLevel machines are used when higher pressure support is required, and travel CPAP devices are ideal for frequent travellers or those wanting a compact backup.
