    "CPAP machine doing the job. Sleeping like a baby, finally. Thank you"

    March 7, 2018

    Product Overview

    The Luna CPAP Machine with Integrated H60 Heated Humidifier from 3B is a single-pressure CPAP machine and humidifier combination designed to provide comfortable sleep therapy. The machine has a large, colorful display designed to help the user navigate through the many comfort features. Also, use the large screen to review sleep data using iCode technology.

    This product is no longer available. We suggest looking at the Luna II CPAP Machine as a comparable alternative to the Luna CPAP Machine. The Luna II is a single pressure CPAP Machine that has a built-in heated humidifier. Looking for an auto-adjusting machine? Try the Luna II Auto CPAP Machine, the auto-adjusting cousin of the Luna 2 CPAP.

    Manufactured by 3B Medical.

    Product Features

    The 3B Luna CPAP Machine with Integrated H60 Heated Humidifier uses comfort features such as Ramp and Reslex to ease the pressure for the user. Ramp peacefully increases the pressure within a set time to adjust the user to the prescribed pressure, while Reslex softens the pressure as the user exhales. A protective delay is built into the humidifier which allows the machine to release air from the humidifier for 15 minutes after the machine has been turned off. The Luna CPAP is a single-pressure machine designed to provide constant pressure throughout the night.

    Integrated Heated Humidifier Included

    Warm the air traveling through the CPAP hose by pairing the machine with the integrated heated humidifier. At times, CPAP therapy can result in dry mouth and congestion. To help diminish these effects, choose between the Luna's five humidification levels. Level 1 offers the lowest amount of humidification, while Level 5 indicates the user has reached the highest level of humidification. The Luna Heated Humidifier is designed to mark the level with the corresponding number of blue lights. For example, if the user selects Level 3, the device will show 3 small, blue lights. If the user selects no humidification, the lights will not turn on.

    Pressure Relief Comfort Features

    Reslex was implemented into the Luna CPAP design to help users adjust as they exhale during sleep therapy. When the feature is turned on, Reslex will begin softening the exhalation automatically. There are three settings available: Level 1 reduces the exhalation with the least change, while Level 3 offers the greatest reduction in pressure.

    The Ramp feature included on the CPAP machine introduces the prescribed pressure to the user over a set period of time. Turn the knob on the front of the machine to extend the Ramp in increments of 5 minutes. Based on the time set, the Luna will continually adjust to reach the prescribed pressure.

    User Friendly Display Screen

    The colorful 2.4 inch screen helps the user to clearly navigate the menu in order to change the default settings or request compliance data. Also, alert messages are designed to appear along the large display to visually notify the user when a situation occurs. Each potential failure emerges in conjunction with a warning sound.

    Data Tracking for Compliance

    Use the iCode app to pull sleep results produced within a specific period of time. The screen displays information such as: compliance hours, average pressure, AHI, snore index, and leak rate. To download these results for further review, put the complete code into the iCode website or use the iCode app on your smartphone to register the QR code located on the machine's display. A smartphone is not included with the purchase of the Luna CPAP machine.
