ResMed machines are among the most widely recommended devices in respiratory therapy, used as part of nightly airway pressure treatment for conditions diagnosed and managed by a clinician. Whether a device has just been prescribed or a replacement is being considered, understanding the range and how each type works is a straightforward and practical starting point.

Understanding the ResMed Machine Range

CPAP: Fixed Pressure Therapy

CPAP (Continuous Positive Airway Pressure) devices deliver a single, consistent pressure throughout the night. The clinician sets the pressure level based on a prior assessment, and the machine maintains that stable airflow continuously. ResMed CPAP machines are designed for reliability and quiet operation, making them a common first recommendation.

APAP: Automatic Pressure Adjustment

APAP (Automatic Positive Airway Pressure) machines monitor airflow on a breath-by-breath basis and adjust pressure within a clinician-set range in real time. This integrated response makes APAP devices suitable for those whose pressure requirements vary across the night. ResMed APAP devices use proprietary algorithms to maintain effective airflow without unnecessary pressure increases.

BiPAP and Bilevel Devices

Bilevel devices, sometimes referred to as BiPAP, deliver two distinct pressure levels: a higher pressure on inhalation and a lower pressure on exhalation. This makes them suitable for patients whose clinician has identified a need for differentiated airway support. ResMed bilevel machines are designed for consistent and comfortable nightly use under clinical guidance.

Key Components and Compatible Accessories

Masks and Cushions

A compatible mask is essential to the effectiveness of any ResMed machine. ResMed produces a range of mask types, including nasal, full face and nasal pillow designs, each available in multiple sizes. The cushion forms the seal between the mask and the face; a well-fitting cushion that maintains its seal is important for stable airflow throughout the night. Cushions are sold separately and have a recommended replacement schedule.

Humidifiers and Tubing

Integrated or compatible humidifiers add moisture to the air delivered by the machine, which can improve comfort during therapy. ResMed's HumidAir humidifier is designed for use with the AirSense and AirCurve device series. Tubing connects the machine to the mask and is available in standard and heated variants. Heated tubing helps reduce condensation within the circuit during nightly use. Tubing and humidifier components are sold separately where not included with the device.

Filters and Replacement Parts

ResMed machines use both fine and standard filter types to maintain airflow quality. Filters are disposable and require regular replacement according to the recommended schedule. Using genuine ResMed replacement parts helps ensure the machine operates as designed and maintains its performance over time.

Choosing the Right ResMed Machine

Follow Clinician Guidance

The type of ResMed machine that is appropriate depends entirely on the prescription and recommendations provided by a qualified clinician. CPAP, APAP and bilevel devices are not interchangeable without clinical review. It is important to confirm the prescribed pressure settings and device type before selecting or purchasing equipment.

Consider Data and Connectivity Features

Many current ResMed machines include integrated data recording and wireless connectivity, allowing therapy data to be reviewed remotely by a clinician. The AirSense 11 and AirSense 10 series, for example, record detailed nightly usage data. This information can support ongoing therapy management and adjustment by the treating clinician.

Matching the Machine to Lifestyle and Environment

ResMed offers compact and lightweight travel-compatible devices, such as the AirMini, designed for use away from a home environment. Standard machines are designed for reliable daily use on mains power. When selecting a device, it is worth confirming whether a humidifier is included or sold separately, and whether the device is compatible with the preferred mask system.

What to Look for When Purchasing ResMed Machines

Genuine and Original Equipment

Purchasing brand new, genuine ResMed equipment ensures compatibility with current accessories and firmware. Third-party or counterfeit devices may not maintain the consistent pressure and airflow performance that genuine ResMed machines are designed to deliver. Always confirm the product is an original ResMed device supplied by a reputable source.

Compatibility with Existing Accessories

Before purchasing a ResMed machine, it is practical to confirm compatibility with any existing mask, tubing or humidifier. Not all ResMed accessories are compatible across all device generations. Key points to verify include:

• Mask connection type: confirm whether the mask uses a standard 22 mm connection or a proprietary ResMed connector.
• Humidifier compatibility: verify that the humidifier model is designed for use with the specific device series.
• Tubing diameter and length: standard tubing is 19 mm or 22 mm in diameter; heated tubing requires a compatible device port.
• Filter type: fine filters and standard filters differ by model; confirm the correct replacement reference number.
• Power supply: confirm whether the device requires a specific power adaptor, particularly for travel use.

Not Included: What to Source Separately

ResMed machines are typically sold as a device unit. The following items are commonly not included and are sold separately: mask, cushion, headgear, humidifier chamber, tubing, filters and power adaptors for international travel. Confirming what is and is not included at the point of purchase avoids gaps in the therapy setup.

Summary: Getting Started with ResMed Machines

ResMed machines span a well-defined range of CPAP, APAP and bilevel devices, each designed for specific therapy requirements as determined by a clinician. Selecting the correct device type, confirming compatibility with masks and accessories, and sourcing genuine replacement parts are the practical steps that support consistent and reliable nightly therapy. For any questions about suitability or prescription requirements, consultation with a qualified clinician is always recommended before making a purchase decision.
