    Cleaning your mask every day is a very important part of mask maintenance. All masks in the Comfort Series can be cleaned in the same manner. Below you will find the three easy steps to keeping a clean mask:

    1. Wash the mask in warm water with a mild soap and air dry; no need to disassemble the mask. Avoid soap with moisturizers.

    2. Wash your face thoroughly before using your mask.

    3. Inspect your mask. Replace the mask if the cushion becomes hardened or if any parts become damaged.

    Even by following these tips, the natural oils in your face will interact with the mask, and over time, the mask will lose its seal. As an informed healthcare consumer, you should be aware of the mask replacement benefits under your healthcare plan. If your plan does not meet your mask replacement needs, talk to your home healthcare provider.

    Comfort Tips

    Respironics has developed unique product features to make positive airway pressure more comfortable to use, such as C-Flex, ramp, humidification, and Comfort Series masks.

    C-Flex lowers the pressure at the beginning of exhalation when many people find therapy most uncomfortable. The amount of pressure relief is based on your breathing pattern and your C-Flex setting. With three C-Flex settings, you have the ability to select a greater or lesser degree of pressure relief that is right for you.

    Your device should be set up with a preset C-Flex setting. You can try other settings by simply pressing the C-Flex button on the front of your device. You may also change the C-Flex setting using the control buttons and display screen. Press the right arrow to scroll to the C-Flex settings page. A screen with three C-Flex settings will appear. Use the C-Flex or plus and minus buttons to increase or decrease the setting. Press the stop/start button to save your setting and return to the mail menu.

    Note: If C-Flex is not enabled on your device, talk to your doctor or home care provider about activating it.

    Ramp is a comfort feature on all M Series devices. Ramp allows you to keep the air pressure low when you are trying to fall asleep. And then it automatically and gradually increases the air until your prescription level is reached. Many users find that using ramp makes it easier to fall asleep. You activate the ramp by pressing the ramp button on the front of your device. Most of the PAP devices allow you to set the starting ramp pressure to the level you find most comfortable. And if you wake up in the middle of the night and have a hard time falling back to sleep, you can activate ramp again by simply pressing the ramp button.

    The humidifier is another piece of equipment that will make your therapy more comfortable Heated or unheated humidification can reduce discomfort associated with common CPAP conditions such as dry mouth, nasal irritation or congestion.

    To make humidification even more comfortable, we’ve made the M Series humidifiers even easier to use. The M Series humidifier features a new easy-turn dial to get the right setting, and it doesn’t need to be reset during the night if therapy is temporarily suspended. Plus, the redesigned “hidden” water chamber is easier to use and easier to fill and delivers continuous humidification throughout the night.

    Comfort Series Masks
    Comfort with your therapy is closely tied with the kind of mask you use. When you find a mask that is comfortable, you have the best chance to enjoy the full benefit of therapy. Respironics Comfort Series line offers a variety of styles, features, and sizes designed to fit many different facial profiles and user preferences. Sometimes getting a better mask fit is as easy as adjusting the headgear – especially if it’s too tight. Adjusting to your mask means learning to accept its presence. It may take some time, so be patient and stick with it.

    Regular use means living a longer and healthier life!
    It is very important to get comfortable with your device so regular, all-night positive airway pressure sessions become part of your nightly routine. People who regularly use positive airway pressure therapy feel healthier and more alert. So make a commitment to accept therapy as part of your life and use your device each night. The more you know about your treatment and sleep apnea, the better prepared you will be to live a longer, healthier, and more productive life.

    Travel Tips

    How to Prepare for Travel

    Traveling with the integrated humidification platform
    To prepare for travel (this includes travel to and from the physician or homecare provider):

    1. Unplug the device and pack the cord and power supply in the front compartment of the carry case.
    2. Verify that the humidifier water chamber is empty and completely dry to prevent water from spilling in the device during travel. You may want to place the humidifier water chamber in the collapsible front pocket of the carrying case with your mask and accessories in case you do not have time to dry the humidifier properly.
