Yes, although you may need to explain to the TSA agent what you are carrying. In the back of the Z1 or Z2 User Guide is a letter that you can carry with you to show the FAA Compliance.
FAA Compliance
The US Department of Transportation (DOT) Final Rule, “Nondiscrimination on the Basis of Disability in Air Travel” (73 FR 27614 which updates Title 14 CFR Part 382), effective May 13, 2009 provides important requirements for the accommodation of passengers with respiratory assistive devices (Ventilators, Respirators and CPAP machines).
In line with these requirements, respiratory assistive devices may be used onboard an aircraft, without further testing by the carrier, provided they have been tested for Electromagnetic Compatibility (EMC) in accordance with the current version of RTCA/DO-160, Section 21, Category M.
Breas Medical has successfully completed testing for the Z2 CPAP System. The Z2 CPAP System complies with RTCA/DO-160, Section 21, Category M and can be considered FAA compliant.
Some airlines may require advance notification before travel, and devices may need to be operated by battery. Breas Medical recommends that customers check with their airline.

No, the data cannot be transferred from one device to another. Data on the Z1 or Z2 will be stored for the usage on the actual unit itself.
The device must be returned to replace the silicone outlet tube. Please contact the home medical equipment supplier or website you purchased your device from, and let them know your unit needs to be returned to the manufacturer for a repair.
The dim light is on a timer and should turn off after a few moments. Unfortunately, there is no way to change the timer on the backlight of the LCD screen.
The minimum voltage you will need to run your Z1 or Z2 device is 14.4 volts.
The Z1 and Z2 run on electricity from 100-240V which means you will not need a converter for international travel. You will only need a plug adapter to fit the right configuration for the country you are visiting.
The tubing comes in two different lengths -- 4 feet and 6 feet slim style -- and is 15 mm in diameter. You can also use standard tubing with the Z1/Z2, which is 19-22 mm diameter.
The most common cause of a pressure increasing, beyond what is necessary, is a leak in the system/mask. It may be a leak in the connections to the mask, or the hose. Please check to make sure these connections fit tightly.
Another reason is an excessive leak at the mask. Please make sure you have a proper seal between the mask and your face.
Check the connection of the tube adapter and the outlet tube (the rubber piece where the tube adapter connects to the machine). If the tube adapter is not properly seated in the outlet tube, the pressure sensor may not be getting the information it needs to regulate the pressure. Also check to make sure your outlet tube is not torn. If it is torn, the device will need to be returned to be repaired.
The last reason could be the Z1/Z2 may be sensing an obstruction, which reads as an apnea, and thus increasing the pressure. This could be caused by congestion, or a mask system that has very low flow rate. If you have a mask with very low flow rate, such as some of the very small nasal pillow masks, you may want to try a mask with less restriction such as a nasal mask. If none of the above are successful, please contact the provider you purchased your Z1/Z2 from.
We have not tested the SoClean for use with the Z1 or Z2, so we cannot recommend the use of this product for cleaning.
If your Z2 is shutting off in the middle of the night, it may be caused by the Auto Start/Stop feature misinterpreting a leak or your mask slipping off your face. It should turn back on by breathing into the mask. If not, press the power button on the Z2 to restart the feature.
If you continue to have issues, you can disable the Auto Start / Stop Feature. When you purchase and receive your Z2 it is defaulted to have Auto Start/Stop enabled.
To disable Auto Start/Stop
• Press and hold the Up Arrow Button and Down Arrow Button at the same time until the Z-Breathe setting flashes.
• Release the buttons.
• Then press and hold the Up Arrow Button and Down Arrow Button at the same time again until AOFF-ON flashes.
• Release both buttons and press the Down Arrow Button once to select "AOFF-OFF".
• Press and hold the Start / Stop Button to save the setting, you will see the word ACCEPT.
• Verify that the screen is now flashing AOFF-OFF. If not, repeat the process.
• To enable the feature, repeat the steps above, but press the Up Arrow Button once to change to Auto Start/Stop, then hold both the up and down arrow buttons until you see the word ACCEPT.
The Z2 is equipped with an Auto Start / Stop feature. This feature will start the treatment automatically when the mask is placed on the face and you start to breathe. It will stop the treatment after the mask has been removed. To restart the treatment, place the mask back on your face and start to breathe through the mask. The Z2s manufactured before June 2024 were shipped with this setting turned on. After June 2024, the feature was turned off.
NOTE: The Auto Start / Stop feature will stop the therapy if a large air leak is detected between the Z2 outlet and the mask. This may also happen at times when the mask is not being worn properly. This common condition should be resolved once all connections are secure, the mask is properly worn, and the Start/Stop button has been pushed or you start breathing into the mask.
NOTE: The Auto Start / Stop feature may not work with the use of a full face mask due to its design. In this case you will need to press the Start/Stop button to start the therapy.
You can disable the Auto Start / Stop feature by following these steps: press and hold the Up Arrow Button and Down Arrow Button at the same time until the Z-Breathe setting flashes. Release the buttons. Then press and hold the Up Arrow Button and Down Arrow Button at the same time again until AOFF-ON flashes. Release both buttons and press the Down Arrow Button to change to AOFF-OFF. Press and hold down the Middle Power Button to save the setting.
To enable the feature, repeat the steps above, but press the Up Arrow Button to change to AOFF-ON. Then press and hold down the Middle Power Button to save the setting.
The current Firmware for the Z2 Auto is 2109. All Z2s manufactured after May 2019 have this firmware installed.
You can change the date and time on your Z1 or Z2 Auto, by connecting it to our Nitelog app on an iPhone/iPad or most Android devices.

Z-Breathe is a proprietary algorithm engineered in the Z2 to smooth out the breathing cycle while enjoying the benefits of CPAP treatment. Typically users experience pressure swings while breathing on a CPAP device. Pressure swings occur as a spike in pressure during exhalation and a drop in pressure during inhalation. Z-Breathe is designed to minimize the impact of spikes and drops while keeping the pressure constant, thereby delivering more comfortable therapy.
Pressure swings can vary between users due to lung capacity and other factors. For this reason we have created 3 levels of Z-Breathe to accommodate individual users’ preferences:
— 1 offers mild pressure swing relief
— 2 is the Default Setting and offers moderate pressure swing relief
— 3 is the most aggressive setting for pressure swing relief
To change the Z-Breathe setting on your device, start with the unit in standby mode (reading 0.0 for the pressure). Simultaneously hold down the UP and DOWN arrow buttons until APAP or CPAP-2 is flashing. Use the UP and DOWN arrow buttons to adjust the setting and hold down the MIDDLE power button until you see the word ACCEPT on your screen. The unit will then return to standby mode.
The Dataviewer Software is no longer supported.
Please follow the steps below to connect to the Nitelog App.
Nitelog only works with the Z1 Auto and Z2 Auto. Verify that they have the Z1 Auto (black) and not the Z1 CPAP (white). On the Z2, look at the logo above the LCD display to see whether just a Z2 or a Z2 Auto.

On the last day of each month, the Z1 Auto only ‘logs’ the time used between the start of usage and midnight. It does not report any time between midnight, and morning of the first morning of the month. Is there a fix to this problem?
Your viewing window may be set incorrectly. In order to fix this, go into chart settings by using the gear button in the top right corner of the main Nitelog screen. Change your usual sleep time to the time you went to sleep and change the hours of sleep to 12. You should now be able to view your data for the night selected.
If Nitelog is giving you an error message that your account is already set up while you are trying to set up an account, try typing in your email address with only lower case letters. This usually corrects the issue.
Once the battery is fully charged, please disconnect your Z1/Z2 machine from your PowerShell and remove the battery from the PowerShell, or it will slowly drain the battery over the course of 2-3 days.
Make sure you hear a clicking noise when inserting the Z1 or Z2 into the PowerShell. If it is still not charging disconnect the Z1/Z2, battery, and power supply and reconnect. Proceed to recharge your unit again for 10-12 hours. If it is still not holding a charge it will need to be sent in for a return by the provider you purchased your unit from. Please keep the following information in mind after charging your Power Shell:
• Disconnect the battery from the PowerShell after a full charge to prevent the battery from slowly draining within a 2-3 day period.
• The battery needs to be charged for 10-12 hours to ensure a full charge.
• The bars of battery life on the LCD screen need to be full, and not blinking.
• The PowerShell battery will not charge while it is operating the Z1/Z2 for treatment. The battery must be charged between treatments.

The Z2 system includes: Z2 device, tube adapter, 6 ft. slim-style tube, power supply cord, custom USB cable, HME (travel humidifier), 2 air filters (one installed in the device), a Q-lite, the User Manual, and the Getting Started Guide. It does not come with a mask. Most people use the mask they are already comfortable with.
The main difference between BiPAP and CPAP machines is that BiPAP machines have two pressure settings: the prescribed pressure for inhalation (IPAP), and a lower pressure for exhalation (EPAP). The dual settings allow the patient to get more air in and out of their lungs.
A fixed pressure CPAP device provides a constant therapeutic pressure. The prescription is written as a single pressure such as 12 cmH2O.
An auto adjusting CPAP provides a variable therapeutic pressure throughout the resting period. The prescription for is written as a range of pressures such as 4-20 cmH20. The therapy will start at the lowest set pressure and then increase as it senses resistance. The Z2 CPAP is no longer available in the US. Only the Z2 Auto is available for sale which can be set either in CPAP or APAP mode according to the prescription.
The warranty on the Z1 is three years from the date the patient purchased the unit from the reseller, with their receipt. If the patient does not have a receipt, the warranty period starts from the time the DME purchased the device plus a two-month grace period.
The warranty on the Z2 is two years from the date the patient purchased the unit from the reseller, with their receipt. If the patient does not have a receipt, the warranty period starts from the time the DME purchased the device plus a two-month grace period.
Please contact us at 855-436-8724, and we would be happy to discuss why the Z2 is, or is not, an appropriate choice for you.
No, a BiPAP prescription is specific to a BIPAP machine and cannot be used for a CPAP machine and vice versa. You will need to discuss this with your doctor if you would like to purchase a CPAP device.

Yes, the Z1 and Z2 CPAPs are FAA compliant for use on airplanes. The FAA compliance letter is in the back of the User Guide. Detach it from the Guide and bring it with you on your flight.
Because the aircraft cabin is pressurized, the CPAP will operate in the same way as on the ground.
No, we currently do not sell solar chargers. Additionally, the Z2 has not been tested with a solar charger, so we are unable to make such a recommendation.
The minimum voltage you will need to run your Z1 or Z2 device is 14.4 volts.
The Z1 and Z2 run on electricity from 100-240V which means you will not need a converter for international travel. You will only need a plug adapter to fit the right configuration for the country you are visiting.
The Z1 and Z2 have been tested at altitudes up to 8,000 feet; operation of the device above 8,000 feet cannot be guaranteed. Note: The Z1/Z2 will work in an aircraft flying higher than 8,000 feet because the cabin is pressurized to 11 to 12 psi, approximately the atmospheric pressure at 6,000-8,000 feet.
The capacity of the PowerShell Extended Life battery is 99.4 Wh. The FAA allows batteries up to 100 Wh in carry-ons baggage on board planes for personal use of passengers. Please consult the FAA website for additional information.
