General Warnings And Cautions - Teleflex ConchaTherm Neptune User Manual

3. General Warnings and Cautions

Warning: For safe operation, only use Hudson RCI Branded Concha Columns, Water Reservoirs,
Temperature Probes and 21-Volt Heated Wire Circuits, as listed in the Hudson RCI Product Catalog.
Warning: Fire Hazard. Do not use the humidifier in the presence of flammable anesthetic gases.
Warning: Burn Hazard. The heating element of the humidifier is hot (as high as 140°C). Allow the
humidifier to cool before handling.
Warning: Burn Hazard. The Concha-Column is hot (as high as 140°C) and may contain liquid at
temperatures up to 80°C. Allow the column to cool before handling.
Warning: Electrical Shock Hazard. Refer all servicing to qualified, trained personnel only.
Warning: This humidifier requires 100-120V ~, (nominal) 60 Hz sine wave output. If used in a
transport vehicle requiring an inverter, do not use square or pulse width modulated sine wave output.
To do so may result in overheating.
Warning: The temperature probes must be properly placed in the breathing circuit before operating
the humidifier. Failure to properly connect the temperature probes will cause the unit to alarm and
shut down.
Warning: Always verify gas flow and airway temperature before connecting the humidifier to the
patient.
Warning: Maintain adequate gas flow through the column and breathing circuit. This will prevent
overheating the column and breathing circuit.
Warning: When using Hudson RCI Heated-Wire Circuits:
• Observe the minimum minute volumes recommended in this manual.
• Do not cover the circuit with sheets, blankets, towels, clothing or other materials.
• Do not apply excessive tension to the heated-wire harness - DO NOT "MILK" TUBING.
• Do not allow the circuit to rest on the patient's bare skin.
Warning: Always monitor tidal volume, minute volume, respiratory rate and all pressures and ensure
that all monitoring alarms are appropriately set and functioning before connecting patient to the gas
delivery system (ventilator, humidifier and circuit).
Warning: Do not leave the humidifier ON, do not turn the humidifier ON and do not exit the pause
mode until there is regulated gas flow through the system. To do so may result in heat buildup,
causing a bolus of hot air to be delivered to the patient. Circuit tubing may significantly soften under
these conditions. Turn the humidifier OFF or place the unit in pause and allow the system to cool
before stopping gas flow.
Warning: The probe alarm is not intended to replace routine physical inspection of the temperature
probe placement. Be sure both probes are in place during operation of heater.
Warning: Do not use a Low-Compliance Concha-Column in continuous flow CPAP applications with
gas flows greater than 50 LPM. There is potential for flooding of the breathing circuit and airway.
Warning: Only use the Comfort-Flo Concha-Column in continuous High Flow Oxygen applications.
Do not exceed 40 LPM in this mode. There is potential for flooding of the breathing circuit and
airway.
Warning: Sudden changes in circuit pressure may cause the water in the column to rise temporarily
and may affect compressible volume.
