  9. Supplemental oxygenSupplemental oxygen can be used with the VPAP Tx.

  10. Antibacterial filters Antibacterial filters can be used with VPAP Tx. Res Med recommends using a filter with a resistance of: 1- less than 2 cm H2O at 60 L/min—when using standard Res Med air tubing 0.75" (19 mm) inner diameter 2- less than or equal to 1 cm H2O at 60 L/min—when using Slim Line air tubing 0.6" (15 mm) inner diameter. CAUTION The Learn Circuit function should be repeated every time the patient circuit is altered (eg, addition or removal of an antibacterial filter or humidifier or change of tubing).

  11. Humidifier • The VPAP Tx is compatible with the HumidAire 2i integrated humidifier. • An external humidifier may be used with the VPAP Tx if it has a water capacity that does not exceed 600 mL and has a resistance that does not exceed 2 cm H2O at 60 L/min. CAUTION • When the VPAP Tx is in use and attached to a humidifier, do not turn off the power source. • The Learn Circuit function should be repeated every time the patient circuit is altered (eg, addition or removal of an antibacterial filter or humidifier or change of tubing).

  12. HumidAire 2i™ • The ResMed HumidAire 2i™ is designed to humidify the air delivered to the airway during CPAP, automatic positive airway pressure (APAP), and bilevel therapy. • Nasal congestion or dryness of the nose, mouth or throat may be experienced during therapy. • These symptoms are caused by dry climates, cold air temperatures, the airflow delivered from the CPAP, APAP, or bilevel system and mouth leak. • Moist air helps relieve symptoms of dryness and can make therapy more comfortable.

  13. HumidAire 2i™ • The HumidAire 2i is intended for single patient re-use in the home environment and multi-patient re-use in a hospital/institutional environment. Contraindications • The HumidAire 2i is contraindicated for use with patients whose supraglottic airways have been bypassed.

  14. WARNINGS • Always place the HumidAire 2i device lower than the level of the patient. If it is placed at or above the level of the patient, heated water may flow down the air tubing and into the mask. • Do not attempt to dismantle the HumidAire 2i docking station. There are no user-serviceable parts inside. Repairs and internal servicing should only be performed by an authorised service agent. • Take care when handling the HumidAire 2i. The water in the water chamber may be hot. • If liquids are inadvertently spilled on the HumidAire 2i docking station, unplug the CPAP, APAP, or bilevel device from the power outlet and allow the docking station to drain and dry before using.

  15. WARNINGS • The water chamber should not be connected to the docking station when transporting the HumidAire 2i in the carry bag. Place the water chamber in a separate compartment in the carry bag. • Make sure that the water chamber is empty and thoroughly dried before transporting the HumidAire 2i. • There exists the possibility that if the device is placed above the level of the patient and is tipped over, or if the tubing is filled with condensate, the mask might fill with water. • Do not operate the HumidAire 2i if it is not working properly or if any part of it has been dropped or damaged. • Keep the power cord away from heated surfaces.
