Welcome to Your Z1 CPAP System
Thank you for choosing the Z1 CPAP System from Human Design Medical– designed,
engineered, and assembled in the USA with you in mind.
The Z1 is specially designed with these features:
• ZBreathe™ – the Z1 automatically reduces the air pressure in the mask to relieve
pressure when you exhale and to level out the pressure differences in your natural
breathing pattern.
• Leak Compensation – the Z1 automatically compensates for minor air leakage
helping ensure the proper treatment pressure is maintained.
• Auto Altitude Adjustment – the Z1 adjusts to altitudes up to 8000 ft above sea level.
• Air Travel – The Z1 adjusts to an airplane’s cabin pressure and is approved for use on
airplanes.
• Upgradable Operating System– the Z1 firmware and software can be easily
updated via the USB Cable and your computer or by using a Micro SD Card.
