General Warnings and Cautions
A warning alerts you to possible injury.
•
Read the entire guide before using the Tango.
•
The advice in this guide should not supersede instructions given by the prescribing
physician.
•
The Tango should only be used with masks (and connectors*) recommended by
ResMed, or by a physician or respiratory therapist. A mask should not be used unless
the Tango is turned on and operating properly. The vent hole or holes associated with
the mask should never be blocked.
Explanation: The Tango is intended for use with special masks (or connectors
vent holes allowing a continuous flow of air out of the mask.
•
When the device is turned on and functioning properly, new air from the device
flushes the exhaled air out through the mask vent holes. If the device is not operating,
insufficient fresh air is provided through the mask, and the exhaled air may be
rebreathed. Rebreathing exhaled air for longer than several minutes can sometimes
lead to suffocation. If there is a power failure or the device machine malfunctions,
remove the mask.
•
The Tango can be set to deliver pressures up to 20 cm H
certain fault conditions, pressures up to 30 cm H
•
If oxygen is used with this device, the oxygen flow must be turned off when the
device is not operating. If oxygen has been left on while the device is not operating,
disconnect the oxygen and wait 30 minutes before turning on the flow generator
again.
Explanation: When the CPAP device is not in operation and the oxygen flow is left on,
oxygen delivered into the air delivery tubing may accumulate within the CPAP machine
enclosure and create a risk of fire.
•
Oxygen supports combustion. Do not use oxygen while you are smoking or in the
presence of an open flame.
•
Always ensure air is flowing from the device before turning on the oxygen supply.
•
Always turn the oxygen supply off before stopping the airflow from the device.
Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration
will vary, depending on where the oxygen is introduced, pressure settings, patient
breathing pattern, mask selection and leak rate.
•
Explosion hazard—do not use in the vicinity of flammable anesthetics.
•
Do not use the Tango if there are obvious external defects or unexplained changes in
performance.
•
Do not open the Tango case. There are no user serviceable parts inside. Repairs and
internal servicing should only be performed by an authorized service agent.
A caution explains special measures for safe and effective use of the device.
•
At low pressures, the flow through the exhalation ports of your mask may not clear all
exhaled gas from the tubing. Some rebreathing may occur.
•
The airflow for breathing produced by this device can be as much as °F (6°C) higher
than the temperature of the room. Be careful if the room temperature is warmer than
90°F (32°C).
*
Ports may be incorporated into the mask or in connectors that are near the mask.
