    About

    The BMC G3 X APAP and CPAP devices represent the newest generation of BMC sleep therapy technology in Australia, engineered to deliver smarter, quieter and more accurate therapy.

    The G3 X builds on the success of the G3 platform with a refined pressure-response algorithm, hardware improvements, and optional Wi-Fi/4G remote connectivity, delivering more accurate therapy, quieter performance, and improved clinician oversight via the PAPLink portal (please get in touch with the BMedical team to create an account). 

    What’s New in the G3 X (vs. G3)

    New Optimised Algorithm

    The G3 X differentiates event types before adjusting pressure — titrating upward only for events likely to resolve with increased pressure, and reducing pressure promptly once resolved, limiting unnecessary pressure exposure. Adjustable Pressure Response settings allow further fine-tuning to individual patient tolerance.

    Bench-tested against five leading APAP devices in 2025, the G3 X demonstrated:

    • Quieter performance than leading competitor devices in independent testing
    • Accurate event identification (including obstructive & central apnoeas, hypopnoeas, flow limitation, snoring, CSR)
    • Faster correction of obstructive events with lower pressure overshoot
    • Appropriate non-response to central events
    • Superior stability during Cheyne–Stokes breathing.
    Much Quieter Turbine (New Hardware)
    • Operates at approximately 26 dB at standard therapy pressure — among the quietest APAP devices available, an important consideration for noise-sensitive patients or bed partners
    • Significantly reduced operational noise on inhalation/exhalation
    • Smooth pressure titration to support comfort and compliance.
    Repositioned Flow Sensor
    • Reduced risk of water ingress
    • Improved signal quality for event scoring.
    Optional 4G Modem Connectivity
    • Available as an optional add-on, selected by the patient
    • Direct real-time remote monitoring via PAPLink Portal.
    Enhanced Performance Under Leak
    • Robust leak compensation that maintains therapy efficacy
    • Validated in bench testing under varying leak conditions.
    Enhanced Patient Comfort Features
    • Optional fine particle/pollen filter suitable for patients with allergic rhinitis or dust sensitivities (recommended replacement every 6 months)
    • Single-press detachable humidifier chamber — no gripping or twisting required, a practical benefit for patients with reduced hand strength or dexterity, including those with arthritis
    • Standard RESlex breathing relief and real-time leak alerts.

    The G3 X is available as an auto-adjusting pressure (APAP) with integrated humidifier & heated tubing and the updated comfort and data features to support adherence and clinical management.

      Sensitivity allows you to adjust how aggressive the algorithm is when responding to apnoeas. BMC Sensitivity Algorithm.pdf
      Sensitivity is divided into 5 levels where 5 indicates the most aggressive pressure adjustment while 1 indicates the least aggressive response
      When activated, the SmartA feature allows the device to adjust the minimum treatment pressure based on P95 for the previous 5 nights of therapy. 
      The G3 device sound is 26dB at 10cmH2O. 
      The most common culprit for a noisy device in any brand is a leak somewhere in the system: 
      1. Check that the mask is sealing well and not damaged- mask leak and type will impact the sound that you hear  from a device.  
      2. Check that the water chamber is ‘clicked in’ to the device correctly and closed completely. The chamber should be flush with the top of the device and clicked together with the front latches during operation
      3. If the sound is described as a gurgling sound- check that the water chamber is not filled above the max fill line – if so remove some of the water to below this line. Check that there is not water (“rain out” ) in the tube- see water in the tube FAQ to fix this 
      4. Check that the dust filter is clear of debris. 
      To check if a heater plate is operating correctly, remove the water chamber and set the humidifier to level 5. Start the device and test the heater plate temperature with your hand. This will take a few minutes to get up to temperature. 
      At level 5 the temperature will be 68 degrees and uncomfortable to touch for more than a few seconds. Check again at level 3 and level 1 to ensure the plate is providing reduced heating. 

      When the humidifier is set to ‘Auto’ mode the heated tubing cannot be selected or adjusted manually. Put the humidifier into manual mode to adjust the heated tubing separately.

      First unplug and re-plug back in. If the tubing remains ‘unconnected’ then there may be a fault with that tube. Try a different tube on the device and if it works then replace the tubing with a new one. If the tubing still remains ‘unconnected,’ there may be a fault with the device that requires further investigation.

      *Ensure that a ResMed power cable is not being used with the BMC device. It does fit in the port but  will not power the heated tubing.

      Water in the tubing or mask is caused by the air cooling as it travels from the humidifier through the  tube and mask and condenses back into water. 
      If there is excessive condensation, check first that the tubing is working  and shows as connected. 
      If this is working, you can either reduce the temperature of the humidifier to reduce the amount of moisture being created OR /and increase the heated tube temperature. 
      If you have tried adjusting settings and condensation is still being experienced, this will be because the air is cooling in the tube so check that the room is not excessively cold or the tubing isn’t directly under an air conditioner that is causing the air to cool too quickly.  If this is happening you may try putting the tubing under a blanket to insulate it from chilly room. 
      If a BMC device is reported to be or appears to be ‘pulsing’ during operation, the flow sensor may have been blocked. This is a result of water ingress into the device that can occur if it has dropped with water inside the chamber, been transported with water in the chamber, or if excessive uncontrolled rainout is allowed to persist.
      To confirm water ingress into the flow sensor, start pressure to the device with water chamber attached and no tubing. On the device screen the flow rate will display in L/min. an unobstructed flow sensor will display a flow rate of 155-170L/min of air. If the flow rate is significantly lower than this, jumping up and down erratically, or reading 0L/min, then water ingress is confirmed.
      If the flow sensor has been damaged by water ingress it may need to be replaced.
      *Note, water damage is not covered under warranty
      • Check to see if there are any messages on the screen. If the accessories alerts are turned on and the time-period set has elapsed, the device will alert to change the accessory until this period is reset. Turn accessory reminders on/off in the Settings menu.
      • Check to see if ‘leak alert’ is turned on. This will alert for high leaks during therapy.
      • If an error message appears on the screen with an error number, please contact
      • BMedical for assistance and let us know the error number to assist in diagnosis of the fault
      • If you are using a Bilevel device- check the screen for alarm messages and make adjustments as suggested on the screen.

      Initially, not all BMC G3 Series devices had a WIFI module installed. If the ‘WIFI’ menu cannot be selected on the device, then there is no module installed. To confirm, check the ‘About’ screen in the device settings menu. It will show the WIFI serial number and PIN code if a module is installed.

      The PM2.5 filter fits inside the housing in the back of the device in place of the standard filter. This filter will protect the device from finer particles of dust and allergens. These are recommended for patients in dusty areas, near construction, in areas with bush fires or if  the patient suffers from allergies or asthma. 
      This filter lasts for 6 months and does not require cleaning. The entire cartridge should be replaced after 6 months of use.

      A BMC G3 Series device does not turn on or is not providing power to heat the humidifier or heated tube, please first check to ensure the AC/DC power cable is working correctly. There should be a green light on the power pack when plugged in. Try a different power cable on the BMC device to see if this powers the unit correctly.

      *Ensure that a ResMed power cable is not being used with the BMC device. It does fit in the port but will not power the heated tubing.

      If power issues persist with a new power cable attached, there may be a fault with the BMC device that requires further investigation.

      SP-100 oximetry kits sold after July 2023 are not automatically compatible with BMC G3 units sold prior to in May 2023. Compatibility is possible but the firmware will need to be upgraded on the G3 device.

      Here are the instructions on how to update the firmware– If you aren’t sure please feel free to contact your BMedical rep for support.
