Description
React Health G3X Auto CPAP Machine with Heated Humidifier and Heated Tubing
The React Health G3X Auto CPAP Machine is a quiet, foam-free sleep apnea therapy device designed to deliver comfortable, personalized treatment throughout the night. Its auto-adjusting pressure technology continuously monitors your breathing and automatically provides the lowest effective pressure needed to maintain therapy.
The G3X Auto CPAP includes a built-in heated humidifier, heated tubing, a full-color display, automatic pressure ramp, RESlex exhalation relief, audible mask-leak alerts, and React Health’s Smart A pressure-response technology.
Foam-Free Auto-Adjusting CPAP Therapy
The React G3X Auto CPAP is built without polyurethane sound-abatement foam. Its advanced auto-CPAP algorithm monitors breathing patterns throughout the night and adjusts therapy pressure in response to changing needs.
This allows the machine to maintain effective airway support while avoiding unnecessarily high pressure.
Key benefits include:
- Foam-free internal design
- Quiet nighttime operation
- Automatic pressure adjustments
- Personalized sleep apnea therapy
- Full-color, easy-to-use display
- Compact integrated design
Smart A Custom Pressure Response
React Health’s exclusive Smart A Custom Pressure Response technology personalizes the machine’s automatic pressure range based on recent therapy sessions.
The system reviews data from the previous five qualifying sessions, including sessions lasting at least four hours with acceptable leak levels. It can then refine the Auto Minimum and Auto Maximum pressure settings to support long-term comfort and therapy effectiveness.
Smart A helps the G3X adapt as the user’s pressure requirements change over time.
Built-In Heated Humidifier
The integrated heated humidifier helps reduce common CPAP side effects such as:
- Dry mouth
- Dry nasal passages
- Throat irritation
- Congestion
- General airway discomfort
Because the humidifier is built directly into the machine, there is no separate humidifier attachment. The removable water chamber can be filled while installed or removed for filling and cleaning.
A convenient preheat function allows the water to warm before bedtime.
Heated CPAP Tubing Helps Prevent Rainout
The included heated tubing maintains a more consistent air temperature as pressurized air moves from the CPAP machine to the mask.
This helps reduce CPAP rainout, which occurs when moisture condenses inside the tubing and creates water droplets, bubbling sounds, or interruptions in airflow.
Heated tubing is especially helpful in cool bedrooms or when higher humidification settings are used.
RESlex Exhalation Pressure Relief
RESlex Exhalation Relief lowers therapy pressure when the user breathes out, creating a smoother and more natural breathing experience.
RESlex can be adjusted based on individual comfort preferences:
- Level 1: Light pressure relief
- Level 2: Moderate pressure relief
- Level 3: Maximum pressure relief
- Off: No exhalation pressure reduction
Automatic Pressure Ramp
The automatic ramp feature begins therapy at a lower, more comfortable pressure while the user is falling asleep. The machine then gradually increases pressure as needed once sleep is detected.
This can make it easier for new and experienced CPAP users to relax and fall asleep without immediately receiving full therapy pressure.
Audible Mask-Leak Detection
A secure CPAP mask seal is essential for effective therapy. If the React G3X detects a significant leak lasting approximately 40 seconds, the machine sounds an audible alert and displays “Leak!!” on the screen.
The user can then reposition the mask, tighten the headgear, or check the tubing connection before returning to sleep.
