E. PRODUCT DESCRIPTION
DV6HH Standard Humidifier
The DV6HH Standard Heated Humidifier System is intended to
warm and add moisture to the pressurized air supplied to the patient
during the treatment of Obstructive Sleep Apnea (OSA). The addition
of heated humidification to the air relieves dryness and irritation to
the patient's airway during OSA therapy. The heated humidifier is
used in conjunction with DV6X series CPAP devices and consists of
a humidifier chamber and humidifier heater.
The humidifier chamber holds enough water for a minimum of 8
hours of operation with the heating unit at the maximum temperature
setting with a system flow rate of 60 L/Min in ambient conditions of
23˚C and 25% R.H. The chamber slides out of the unit for cleaning
and filling without adjusting tubing connections. The chamber
separates for easy cleaning but, when assembled, maintains a leak-
free seal to a maximum operating pressure of 30 cmH O.

Heat transferred from the heater to the chamber raises the efficiency
of the DV6HH system. The patient controls the heater plate
temperature using the rotary knob on the attached CPAP device in
conjunction with the device's display to provide the appropriate level
of humidification depending upon environmental conditions and
individual preference.
DV6HHPD PulseDose ® Humidifier
®
The Humidifier PulseDose Valve Module is an optional plug-in
accessory for the DV6HH Heated Humidifier that offers two primary
advantages: it saves power and water by eliminating wasted
humidification during exhalation, and it is able to provide maximum
humidification without inducing rainout in the patient tubing.
The PulseDose module relies on the heated humidifier to provide
pressurized and humidified air, which the module releases to the
patient upon inhalation. The valve module releases pressurized air
without humidification to the patient during exhalation. This valve
action saves water by only using humidity during half of the
breathing cycle.
