Z-Breathe for the z1 xpap machines

Z-Breathe™. More natural breathing.

One of the greatest issues cpap users complain about is the difficulty in exhaling against the pressure exerted by the cpap machine. The Z1™ cpap machine uses our proprietary Z-Breathe™ algorithm that learns from your breathing pattern and relieves machine pressure on exhalation.
