ResMed AirSense 11 AutoSet CPAP Machine

The ResMed AirSense 11 AutoSet is ResMed's premium auto-adjusting CPAP machine — and the highest-selling CPAP in the AU market. Built on the AirSense 11 platform with a contemporary touchscreen design, the AutoSet uses ResMed's clinically-proven auto-adjusting algorithm to vary therapy pressure breath by breath, matching your real-time breathing patterns through every position change, every REM cycle, and every seasonal shift. Three therapy modes (APAP, AutoSet for Her, and fixed pressure CPAP) make it the single most versatile CPAP machine on the market — one machine, every therapy scenario. Includes integrated HumidAir 11 humidifier, ClimateLineAir 11 heated tube, ultra-quiet 27 dB operation, 4G cellular data tracking, and ResMed's myAir Personal Therapy Assistant for new-user onboarding.

Key Features

• AutoSet auto-adjusting algorithm: Varies pressure breath by breath within a prescribed range — increasing when it detects airway resistance, easing off when your airway is clear. Clinically proven to deliver effective therapy at the lowest comfortable pressure.
• Three therapy modes in one machine: APAP (auto-adjusting), AutoSet for Her (gentler pressure ramps designed for female OSA patterns), and CPAP (fixed pressure). Switch between modes as your prescription evolves — no new machine required.
• Large colour touchscreen: Tap-and-swipe navigation replaces the AirSense 10's dial-and-button interface. Most users find it more intuitive, especially in low light.
• Integrated HumidAir 11 heated humidifier: Built into the chassis with auto-adjusting temperature management. Adjustable humidity levels plus auto Climate Control mode.
• ClimateLineAir 11 heated tube included: Mask-end temperature sensor maintains warm humidified air all the way to your mask, eliminating rainout (condensation in the tube).
• Ultra-quiet 27 dB Easy-Breathe motor: About as loud as a quiet whisper — one of the quietest CPAP machines available, ideal for light sleepers and bed partners.
• 24% smaller, ~10% lighter than the AirSense 10: Compact bedside footprint and easier to travel with than the previous generation.
• AutoSet Response comfort setting: For users with high-pressure intolerance — gentler pressure increases for a smoother night's sleep.
• AutoRamp with sleep onset detection: Starts at a comfortable low pressure and gradually ramps to therapy pressure once it detects you've fallen asleep.
• SmartStart: Therapy begins the moment you breathe into the mask — no buttons to press. Stops automatically when the mask is removed.
• Expiratory Pressure Relief (EPR): Softens pressure on exhalation for a more natural breathing feel — reduces the fighting-the-machine sensation.
• Built-in 4G cellular + over-the-air updates: Automatic nightly therapy data upload (AU network coverage); firmware updates pushed wirelessly without USB or service visits.
• myAir app + Personal Therapy Assistant: Interactive voice-guided videos walk you through equipment setup and mask fitting; daily therapy data and Care Check-In coaching for the first month.
• Advanced event detection: Identifies Central Sleep Apnea (CSA), RERA (Respiratory Effort Related Arousal), and Cheyne-Stokes respiration — flagged to your clinician via the AirView portal.
• Ambient light sensor + auto-dimming screen: Screen brightness adjusts to room light and dims automatically when therapy starts. No bedside glare.

The AutoSet Algorithm — Why It Matters

The AutoSet algorithm is the single most clinically-published auto-titrating algorithm in CPAP therapy, with decades of clinical research behind it. Unlike older auto-CPAP algorithms that respond reactively to events that have already occurred, AutoSet monitors breath-by-breath flow patterns and increases pressure before an obstruction completes — keeping your airway open with the minimum pressure required at any given moment. When your airway is stable, the algorithm reduces pressure to improve comfort. The result: more effective therapy at lower average pressures than fixed-pressure CPAP, which is why AutoSet is the default recommendation for most newly-diagnosed sleep apnea patients in Australia.

Three Therapy Modes — One Machine

The AirSense 11 AutoSet's quiet superpower is its mode flexibility. The same machine runs in three distinct therapy configurations:

• AutoSet (APAP): Auto-adjusting pressure between your prescribed minimum and maximum. The default mode — adapts breath by breath. Recommended for most users.
• AutoSet for Her: Auto-adjusting algorithm with gentler pressure ramps, designed for the more flow-limited and REM-dominated obstructive patterns common in female patients with mild-to-moderate OSA. Backed by ResMed's For Her clinical research program.
• CPAP (fixed pressure): Delivers one constant pressure all night — set to your prescribed level. The same mode the AirSense 11 Elite uses exclusively.

This matters because your prescription needs may change over time — weight changes, REM sleep patterns, seasonal congestion shifts, or a switch from fixed to auto-adjusting therapy on your clinician's recommendation. With the AutoSet, you can shift modes without buying a new machine.

AirSense 11 AutoSet vs AirSense 11 Elite — Which Should You Choose?

The AutoSet and Elite share identical hardware — same chassis, same touchscreen, same humidifier, same heated tube, same data tracking, same quiet motor. The only difference is the therapy algorithm:

• AirSense 11 AutoSet (this machine): Auto-adjusting APAP within a prescribed range, plus AutoSet for Her, plus fixed pressure CPAP mode. Maximum flexibility.
• AirSense 11 Elite: Fixed pressure CPAP only. Simpler, slightly cheaper.

The AutoSet is the right pick for most new CPAP users: APAP therapy is generally more comfortable than fixed pressure, the For Her algorithm is the only AU machine offering gender-specific OSA therapy, and you keep the option to switch to fixed pressure mode if your prescription specifies that later. The Elite is worth considering only if you have a stable, well-titrated fixed pressure prescription and the small price saving matters to you.

AirSense 11 AutoSet vs AirSense 10 AutoSet — Which Generation?

Both machines run the same AutoSet algorithm and deliver clinically equivalent therapy. The decision usually comes down to interface preference and form factor:

• AirSense 11 AutoSet (this machine): Touchscreen interface, contemporary design, 24% smaller, 10% lighter, over-the-air firmware updates, myAir Personal Therapy Assistant for new-user onboarding.
• AirSense 10 AutoSet 4G: Established dial-and-button interface, slightly larger footprint, proven hardware reliability over a decade of clinical use.

The AirSense 11 is generally the better choice for new CPAP users (the touchscreen and myAir setup videos lower the learning curve). The AirSense 10 remains a strong pick for users replacing a previous AirSense 10 who prefer the familiar interface.

Prescription Pre-Set Service

If you have a CPAP prescription with specific pressure settings — whether APAP min/max or a fixed CPAP pressure — CPAP Club can pre-configure the AirSense 11 AutoSet to your prescription before shipping. Upload your prescription when you place your order and the machine will arrive set to your prescribed therapy, ready to use the first night. No need to navigate the clinician menu yourself.

Therapy Data and the myAir App

The built-in 4G cellular modem automatically uploads your therapy data after each night's session (Australian network coverage only). Therapy data appears in ResMed's myAir mobile app and online portal, showing usage hours, leak events, AHI (Apnea-Hypopnea Index), mask seal quality, and AutoSet pressure-response patterns. The Personal Therapy Assistant in the myAir app walks new users through device setup and mask fitting with voice-guided interactive videos — particularly helpful for first-time CPAP users. Your sleep clinician can also access the data remotely via AirView for therapy adjustments without an in-person appointment.

The AirSense 11 AutoSet works with any CPAP mask using a standard 22 mm cuff connection — the full ResMed range (AirFit F30i, F30, F40, N30i, N20, P30i, P10), Fisher & Paykel masks (Solo, Vitera, Evora, Brevida, Eson, Simplus), and Philips Respironics masks (DreamWear, Amara View).
