InH2®Heated Humidifier User Manual V2.7
English
The InH2®Heated Humidifier is designed only for use with specific BMC
RESmart®CPAP/Auto CPAP or BPAP devices. Do not use InH2®with any other
devices.
The humidifier moistens the air delivered by the BMC RESmart®CPAP/BPAP
devices.
The InH2®Heated Humidifier is only used for single patient and must not be
re-used on another person. This is to avoid the risk of cross-infection.
The InH2®Heated Humidifier is not intended for use with a patient whose
upper airways have been bypassed.

Warnings & Cautions
IMPORTANT!
• Read all instructions before using the humidifier.
• Use only with BMC RESmart®devices whose instructions specify the use of
this humidifier.
CAUTIONS!
• Indicates the possibility of damage to the device.
• US federal law restricts this device to sale by or on the order of a physician.
• If fluids are spilled onto the humidifier platform, unplug the power cord from
the AC wall outlet and allow the humidifier platform to drain and dry before
using.
• Take precautions to protect furniture from water damage.
WARNINGS!
• Indicates the possibility for injury to the user or the operator.
• Use the humidifier only for its intended use as described in this manual.
• Use only accessories recommended by BMC.
• Never operate the humidifier if any of the parts are damaged, if it is not
working properly, or if the humidifier has been dropped or mishandled. Do not
use the humidifier if the water chamber is leaking or damaged in any way.
Have any damaged parts replaced before continuing use.
• Never touch the heater plate unless the humidifier is unplugged and the plate
has cooled down.
• This equipment is not suitable for use in the presence of a flammable
anesthetic mixture with air or with oxygen or nitrous oxide.
• Periodically inspect the power cord for signs of wear or damage. Replace if
necessary.
•Do not operate the device in direct sunlight or near a heating appliance
because these conditions can increase the temperature of the air coming out
of the device.
• When humidifier is used outside the specified ambient temperature range or
humidity range, the performance of humidifier will be compromised.

Daily Use
1. Fill the chamber to the fill line with water (approx. 350 ml) from the outlet
port. Distilled water is recommended. Do not overfill the water chamber.
CAUTION!
Always remove the chamber from the humidifier before filling with water.
2. Press down the spring loaded heater plate with the water chamber and slide
the chamber into place. Make sure the rubber connector on the inlet port fits
securely over the RESmart®device’s air outlet.
3. Connect the flexible tubing to the outlet port on the water chamber.
CAUTION!
Avoid moving or tilting the humidifier when the water chamber has water in it.
4. When the RESmart®device begins blowing, the humidifier will work
automatically. The yellow indicator light on the humidifier will turn on. Press
the humidifier button can turn off or restart the humidifier.
5. The ideal humidity setting depends on room temperature and humidity.
Initially, a setting of 3 is recommended. You can adjust this setting at any time.
Please adjust the humidifier setting according to the CPAP User Manual.
IMPORTANT!
When the air flow is turned off, the humidifier will automatically shut off.
Cleaning
The water chamber should be cleaned daily or after each use.
WARNING!
Emptying and cleaning the water chamber daily will help to prevent mold and
bacteria growth.
WARNING!
Allow the water in the chamber to cool down to room temperature before
removing it from the humidifier.
WARNING!
To avoid electrical shock, disconnect the power cord of RESmart®device
before cleaning the humidifier. DO NOT immerse the humidifier into any fluids.

propagation is affected by absorption and reflection from structures, objects and

aField strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM
radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in
the location in which the RESmart®is used exceeds the applicable RF compliance
level above, the RESmart®should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the RESmart®.
bOver the frequency range 150 kHz to 80 MHz, the field strengths should be less than
3 V/m.
