Lightweight for Travel, Great for Home Too!:The Z2 CPAP builds on the form of the original Z1 with a more advanced, quieter motor and improved software systems. The Z2 is tiny so it fits easily in your hand; and ultra-light at just 10.4 ounces. It is a great everyday machine that is also ideal for travel, packing easily in carry on luggage or any travel bag.
Fixed Pressure Therapy with a Ramp for Comfort: The Z2 CPAP delivers fixed therapy CPAP pressure at prescribed settings between 4-20 CM. For people who prefer to fall asleep with therapy at lower pressure levels, the Z2's ramp feature allows you to start your pressure at a lower setting and ramp it up over time to let you adjust more gradually to sleep therapy.
Z-Breathe Pressure Relief: Z2 delivers a more natural breathing experience with a proprietary feature, called Z-Breathe, that smooths therapy pressure -- reducing spikes in pressure during exhalation and drops in pressure during inhalation -- to deliver more comfortable therapy. Z-Breathe has 3 settings so you can set it to suit your own personal needs.
Whisper Quiet: The Z2 has a new quieter motor built for sleep so it is very quiet. In fact it's one of the quietest APAPs on the market, producing only 26 dBA on average of sound during operation.
Auto Stop Ease of Use: The Z2 CPAP is programmed to stop delivering therapy within seconds of the mask being removed from the face or when a large leak is detected. No more fumbling to find the stop button in the dark.
Auto Altitude Adjusting: The Z2 CPAP automatically adjusts to altitudes up to 8,000 feet above sea level; and complies with FAA for use on airplanes. When traveling outside the US the Z2 will convert the voltage automatically so you can continue enjoying safe and comfortable sleep therapy wherever your next adventure takes you. (Plug adapter may be needed outside of North America).
Optional PowerShell Integrated Battery: For nights away from fixed power the optional PowerShell with Extended Life Battery Pack provides an innovative, integrated solution, merging the machine and battery in one convenient package. The PowerShell holds one battery that will last 1-2 nights between charges; and batteries recharge using the Z2's standard power supply so there are no extra cords to worry about. For extra nights away just add additional batteries! The PowerShell can also be used as a backup power supply, automatically taking over during a power outage or blackout.
