Adaptive pressure control
The BMC G3 Auto CPAP continuously monitors your breathing to automatically adjust pressure in response to apneas, hypopneas, flow limitations, and snoring. By increasing pressure only when needed and easing back during stable breathing, it promotes more natural sleep compared to fixed-pressure therapy. The device also features Smart C technology, which automatically fine-tunes your treatment pressure every 5 days based on key indicators like AHI and SNI. This ensures consistent, effective therapy without the need for constant manual adjustments.
Intelligent comfort
The built-in heated humidifier delivers consistent moisture to the therapy air, helping reduce dry mouth, nasal dryness, and throat irritation commonly associated with CPAP use. Improved humidification comfort supports better long-term therapy adherence, especially in dry environments or colder seasons. The integrated design keeps the system compact while allowing easy access for filling and cleaning.
To further enhance comfort and ease of use, the BMC G3 features a Pre-Heat function, warming the humidifier water before therapy begins for more comfortable airflow from the first breath. The AutoSTART function automatically begins therapy as soon as breathing is detected, eliminating the need to press buttons and making nightly use smoother and more intuitive.
Quiet and sleep-friendly operation
Engineered with advanced noise-reduction technology, the BMC G3 Auto CPAP System (A20) operates at a whisper-quiet 28 dB to ensure a peaceful night for everyone involved. This ultra-low sound level is specifically designed to minimize sleep disturbances, preventing the mechanical hum of the machine from waking either the user or their bed partner. By prioritizing acoustic comfort, the G3 helps establish a significantly calmer and more serene bedroom environment, which is essential for those adjusting to treatment.
