Evaluation: Metran JPAP Continuous Positive Airway Pressure (CPAP) Unit

December 30, 2019 | Evaluations & Guidance


  • The JPAP is used to provide noninvasive positive airway pressure breathing therapy for the treatment of OSA in spontaneously breathing adult patients. It must be used with a CPAP mask (full face mask, nasal mask, or nasal pillow). The mask and tubing can be either purchased together with the device or purchased separately. It is not a life-support device and does not provide continuous breathing support.
  • Major components and software features:
    • Control unit
      • Size: 9.2 × 13.0 × 3.6 cm (3.6 × 5.1 × 1.4 in)
      • Weight: Approximately 300 g (0.66 lb)
    • CPAP unit
      • Size: 9.8 × 15.8 × 5.3 cm (3.9 × 6.2 × 2.1 in)
      • Weight: Approximately 360 g (0.79 lb)
      • Multilingual selection available: English and Japanese
      • Therapeutic pressure range: 4 to 20 cm H2O. Adjustable in the clinician's interface only.
      • Two modes available, which can be changed in the clinician's interface only:
        • CPAP: The clinician sets a therapeutic pressure between 4 and 20 cm H2O, which the device maintains throughout the night.
        • Automatic positive airway pressure (APAP): The clinician sets both a minimum pressure above 4 cm H2O and a maximum pressure below 20 cm H2O. The device will adjust the therapeutic pressure between these settings throughout the night in response to the frequency of apnea episodes. We did not test the APAP algorithm as part of this Evaluation.
      • Comfort features:
        • Pressure ramp (initial pressure): Initial pressure starts at the selected low pressure and slowly increases to the therapeutic pressure over a short period of time. i) There are two options for initial pressure: 2 or 4 cm H2O. ii) Ramp time adjustable from 0 to 45 min, in five-minute increments.
        • Natural Support (NS) function: Inhalation support and exhalation support to provide easier inhalation and exhalation—as close as possible to natural breathing. Adjustable from 0 to 5 cm H2O.
      • Drying mode: Used to dry the standard tubing or optional Hummax QE humidification system tubing. Drying time is 180 minutes for both standard tubing and Hummax QE tubing. Maximum flow rate will be applied when drying the Hummax QE tubing, and low flow rate will be applied when drying the standard tubing.
      • Memory: Up to one year of data on the 8 GB SD card
      • 2.4-inch color LCD, non-touchscreen display
    • Accessories and consumables
      • Flexible plastic nonheated tubing to connect device to mask (also called general breathing circuit): Length of 1.8 m (5.9 ft), with internal diameter of 15 mm (0.6 in)
      • Air filter must be cleaned every week as recommended by Metran and replaced every eight to 12 months.
      • Mask: The patient can select the type of mask depending on preference: Nasal mask, full face mask, or nasal pillow. Note: While the device must be used with a CPAP mask, the mask can be either purchased with the device or purchased separately. Any CPAP mask with a passive exhalation port can be used with this unit. Noninvasive ventilation (NIV) masks do not have a passive exhalation port and can only be used with ventilators that have an active exhalation valve. Using an NIV mask with this or any CPAP unit will result in rebreathing a potentially dangerous amount of CO2.
    • Carry bag
    • User manual
    • JPAP cloud-based data management solution that can be downloaded to the patient's or clinician's computer or smartphone via the Apple App Store or Android Play Store. Currently available only in Japan.
  • Optional component: Hummax QE humidification system—a nonheated and nonadjustable humidifier that comprises tubing and a water reservoir. Humidification can only be accomplished when using the Hummax QE. The hydrophobic filter membrane inside the Hummax QE's tubing adds moisture to the dry air supplied by the blower.
  • The JPAP is primarily used in the patient's home but can...
