1. AirMini Tubing and ActiveAir technology

1.1. Why does the AirMini tube have different connectors?

The AirMini tube has unique proprietary connectors to connect to the AirMini machine and compatible
masks, including ResMed 20 Series masks, and AirFit P10 for AirMini mask. This proprietary air
tubing enables the use of new technologies for CPAP therapy, including the ActiveAir vent, HumidX
waterless humidification and the miniaturised AirMini machine, while maintaining ResMed's high
standards for effective therapy. The AirMini tube enables an easy transition from AirSense, or other
CPAP systems, to AirMini systems via the small and simple mask connectors compatible with
ResMed latest masks.

1.2. What is ActiveAir Technology?

ActiveAir technology is an innovative mask vent that reduces the excess flow that is wasted by
traditional mask vents, whilst maintaining sufficient washout of exhaled CO2. The ActiveAir vent
continuously responds to the patient's CPAP mask pressure to control vent flow. As a result, a
reduction in the vent flow reduces the overall flow output required for the CPAP machine, enabling a
smaller blower that requires less power. By eliminating excessive flow, ActiveAir enables the AirMini
to be the world's smallest CPAP device at time of its initial launch, while maintaining ResMed's high
standards for effective therapy.

1.3. How does the ActiveAir technology work?

Typically, masks feature a vent, comprised of one or more fixed orifices, to eliminate expiratory gases
before the next inspiration. This minimizes CO2 rebreathing and allows a critically sufficient vent flow
at the minimum PAP pressure, with higher flows resulting at higher pressures. Vent flows higher than
this critical flow provide no additional benefit.
The ActiveAir includes a pressure activated silicone membrane valve that responds to the CPAP
pressure. As pressure increases in the mask, the ActiveAir reduces vent flow to a level that maintains
CO2 washout from the system while reducing the overall flow output required at higher pressures of
the AirMini device.
