BMC G3 Auto CPAP Machine

The BMC RESmart G3 A20 Auto CPAP Machine is an automatic positive airway pressure device designed for the prescribed treatment of obstructive sleep apnea in adults. Its intelligent Auto CPAP technology monitors breathing and adjusts the delivered pressure within the prescribed range, providing personalised therapy throughout the night.

The G3 A20 supports both Auto CPAP and fixed-pressure CPAP modes. Comfort features include Auto Ramp, Reslex exhalation-pressure relief, an integrated heated humidifier, and optional heated tubing. These features help users begin therapy gently, breathe out more comfortably, and reduce dryness or condensation during treatment.

A 3.5-inch full-colour display provides clear access to settings and real-time therapy information. The PUSH water chamber allows water to be added conveniently, while preheating can warm the humidifier before therapy begins. Therapy information can be recorded through an SD card, iCode reporting, and compatible wireless services.

Its compact design, quiet operation, and wide-range power input make the BMC G3 A20 suitable for regular home-based CPAP therapy in Bangladesh.
