General Warnings
A warning alerts you to possible injury. Specific warnings and cautions appear next to
the relevant instructions in the manual.
• Use the H4i only for its intended use as described in this manual.
• Make sure that the water chamber is empty before transporting the H4i.
• The H4i is designed only for use with specific ResMed PAP devices. Do not use the
H4i with any other PAP device.
• The H4i should only be used with delivery tubes or accessories recommended by
ResMed. Connection of other delivery tubes or accessories could result in injury, or
damage to the device.
• The H4i, including the associated tubing, is for single-patient use and must not be re-
used on another person. This is to avoid the risk of cross-infection.
• 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 heated
water. The H4i should therefore be used with caution in patients who are unable to
guard their airways, or are unable to pull the mask off, for example following a stroke.
Attention should be given to the relative risks and benefits.
• Do not attempt to dismantle the H4i
docking station. There are no user-serviceable
parts inside. Repairs and internal servicing should only be performed by an authorized
service agent.
• If liquids are inadvertently spilled into or on the H4i docking station, unplug the PAP
device from the power outlet. Disconnect the docking station from the PAP device and
allow the docking station to drain and dry before using.
• Do not operate the H4i if it is not working properly or if any part of the PAP device or
H4i has been dropped or damaged.
• Keep the PAP device power cord away from hot surfaces.
• Do not drop or insert any object into any opening or tubes.
• Do not use the H4i in the presence of flammable or explosive materials.
• Explosion hazard—do not use in the vicinity of flammable anesthetics.
• Follow all precautions when using supplemental oxygen.
