Servicing:
Beyond the replacement of the back panel fuse or the controller cable, there are no
user serviceable parts associated with the ANAPODTM Humidification System.
Disconnect AC plug from the AC power connection before replacing the fuse or
performing any service related functions.
Replacing the main fuse (Refer to Figure A): To replace the (2) main fuses, locate
the AC inlet and remove the power cord. The center section of the AC inlet
houses the fuse holder and is opened by using a small standard screwdriver
to gently pry the center section loose. Once the fuse holder has been dislodged,
the fuse holder easily slides out and the fuses may be replaced. After replacing the
failed fuse(s) with the same rated fuse, insert the fuse holder back into the AC inlet
housing and plug in the AC power cord.
now ready to use.

The ANAPOD™ Humidification System consists of the ANAPOD™ Controller, ANAPOD™
Humi-Therm Heated and Humidified Breathing Circuit, Power Cable, Controller Cable.
4. The ANAPOD™ should be used by personnel trained in use of heated humidification
in a gas delivery system.
Do not use at a flow rater greater than 12 LPM. At flow rates greater than 12 LPM heat
and humification will be reduced.
The ANAPOD™ Humidification System and associated breathing circuit is a wick-type
anesthesia gas heated humidification system intended for use in an operating room
setting, post anesthesia care unit setting, or for patient transport. The system is designed
to heat and humidify cold dry medical gases.
•
Use only with cable assembly and power cable supplied by Westmed, Inc.•
Position the ANAPODTM Controller such that the front panel controls and connectors,
and rear panel are easily accessible. A pole mount bracket is provided.
•
The ANAPODTM Humidification System is used to heat and humidify dry gas as
recommended by a physician.
Humidification System controller and Heated Breathing Circuit should
•Do not use the ANAPODTM Humidification System at an altitude above 9,500-ft or
outside a temperature of 16°C to 45°C. Using the device outside this temperature range
or above this altitude can affect the quality of the therapy or injure the patient.
The ANAPODTM Humidification System will provide heat and humified gas at flow rates
up to 12 LPM.
The ANAPODTM Humidification System is intended for use with patients whose upper
airways have been bypassed. It may also be used with patients whose upper airway
have not been bypassed.
Covering breathing tubes with a blanket or heating them in an incubator or with an
overhead heater can affect the quality of the therapy or injure the patient.

1. Ensure the ANAPODTM Humidification System is set up correctly per the individual circuit product
instructions for use. Specific instructions for use of the breathing circuits are provided in their
individual packaging.
3. The heated wick circuit will remain at a constant temperature regardless of flow if you preheat the
system. Condensation will form along the inside of the tubing. As the water in the wick circuit is
depleted, the condensation will slowly dissipate beginning at the machine end of the circuit. When
the last 6 inches of the breathing circuit shows condensation additional water should be added.
4. Turn the On/Off control on the back panel of the ANAPODTM Humidification System to “ON”.
5. Set the Temperature Control to the desired temperature 34° – 45°C. To increase temperature,
press UP arrow button, and to decrease temperature, press DOWN arrow button. Temperature
setting can be achieved by momentarily pressing arrow button, or press and hold until the desired
temperature is reached. Set temperature can be displayed at any time when the UP arrow button
or DOWN arrow button is pushed.
6. Set gas flow to desired settings on the gas source equipment or flowmeter.
7. Ensure the desired temperature setting in the heated wick circuit is reached before connecting
the circuit to the patient airway. Confirm the temperature on the front panel display.
8. To stop treatment, turn the On/Off Control to “OFF”. Disconnect the circuit from the cable assembly
by depressing the latch on the white connector and separating the connectors.
9. Dispose of the used circuit when the procedure is completed (all disposable products should be

2. To add water remove screw cap from water bottle included with ANAPOD™ circuit. Aspirate 20 ml
of water from the water bottle into syringe (Refer to Figure B). Attach syringe to the one-way valve
and inject 20 ml of water into the tube and circuit. Aspirate another 20 ml into the syringe and inject
into the tube for a total volume of 40 ml. There should be no pooling of water within the circuit. The

water. Add approximately 12 cc of water for each additional hour of use. If you accidently overfill the
circuit, simply drain excess water at the end of the tube. The ANAPODTM cable assembly connects to
the front of the controller. The opposite end of the cable assembly has a white 4-pin plastic connector
that connects to the 4-pin plastic connector on the heated wick circuit. These two connectors lock
together with a “snap” and are “keyed” to prevent improper connection.

Humidification System and heated wick circuit
Temperature Controls buttons: Sets the desired temperature.
Over Temperature Alarm: Indicates the wick circuit internal
temperature probe has detected temperature at above 47.5° C.
Probe Sensor Alarm: Indicates a probe failure or circuit disconnect.
Temperature Measurement:
The ANAPODTM uses one temperature sensor which is located inside each heated
wick circuit. There are no external probes to attach. This probe is calibrated to
measure the temperature of the flowing gas at the patient end of the wick circuit.
As with all heated systems, there is a certain drop in temperature in unheated
wyes, elbows, and ET tubes. You can expect a temperature drop of approximately
4 - 5º C from the wick circuit outlet to the inlet of the ET tube under normal operating
room conditions. It may be necessary to overcome heat loss in the last few non
heated inches of the tubing, cuff, patient wye, elbow and/or ET tube. You may also
need to compensate for ambient temperatures and/or low airflows. Using the
ANAPODTM Humidification System outside of the operating temperature range of
16º C to 45º C has the potential to affect perfomance. It is recommended that it be
kept within this temperature range during use. Testing shows the following typical
temperature drops between wick circuit output and ET tube:
•Power cord third conductor is only a functional earth
•Gas Path Resistance: 0 to 0.06 cmH2O / Liters/Minute (at maximum flow rate)
•Gas Path Compliance: 2.5 to 2.8 mL/cmH2O
(To test this alarm, disconnect cable while controller is ON.)
All alarms generate both a visual indication and an audible alarm,
and are Low Priority alarms. The audible alarm can be silenced for
2 minutes by pressing the Alarm Silence button; however, the alarm
LED will remain illuminated as long as the alarm condition exists. As
a reminder, audible alarm will initiate again if condition is not resolved.
All alarms will disable the heater in the wick circuit.
