Z-Breathe for the z1 xpap machines

Z-Breathe™ Comfort Feature

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 is designed to minimize the impact of spikes and drops while keeping the pressure constant, thereby delivering more comfortable therapy.
