numerically displayed. In addition, if using a heated breathing tube, an estimate
of the endo-tracheal temperature is displayed (see Note on Inspiratory
temperature)
Data Logging Panel
The left side panel displays temperature data sent from the controller with a
date and time stamp derived from the computer’s clock, and the system status
code.
Procedure Information button
Brings up an editable form regarding the procedure.
Equipment Procedure details, and general Notes can be recorded. This data is
saved with the temperature records when recording is activated.
Record Data button
Brings up an open file dialog window. Select a file name and browse to the
destination that the data file will be recorded to. On closing this dialog,
recording begins, and the Data Log file (CSV format) is declared in the Data Log
file status box
Stop Record button
Stops the recording and closes the data file.
Clear Log button
Clears the Data Logging Panel display. Note that this does not affect the
recording of data to file.
Annotation Entry Panel
Consists of two tabs; The Protocol tab and an Comment Annotation tab
Set Temp
Displays the controller’s set point temperature.
Heating Indicator
Displays when power is being applied to the heater element.
Protocol Annotation tab
Allows date / time stamped protocol comments to be added to the recorded
data file. ( See Protocol annotation below) To add a protocol comment to the
data file either:Click on the appropriate button F1 to F12 (C) on the annotation panel
OR Press the appropriate F key ( F1 to F12 ) on the keyboard
Comment Annotation
Allows date / time stamped anaesthetic Flow, concentration and general notes
to be added to the recorded data file

Menus
File Menu
New (file menu)
Starts a new file for data log recording.
Open (file menu)
Opens a file for recording purposes.
Export to CSV
(file menu)
Exports an opened file to CSV (comma separated values). This format can be
directly opened by Excel such that each column represents a value.
Exit (file menu)
Closes the Heated Breathing Circuit software.
Setup Menu – (Controller Options)
Figure 2: Controller Options Setup Screen
The Controller Setup window (Figure 2) when connected to the controller, displays the current system set up
data in the left column (Current Setup).
In the user mode, the white boxes in the right column pertaining to control temperature, hysteresis
temperature, and default temperature unit may be adjusted. When the required setup is acceptable the
SAVE button writes the new set up data to the controller (stored in non-volatile memory and will be retained
when the heated breathing controller is powered down).

After writing the required data to the controller, this information is then read back from the controller to
verify a correct write operation and the verified data is then shown in the current HBC setup column.

The protocol annotation allows repeated use of known annotation points to be recorded. For instance; the
start of a procedure, induction, etc. Up to twelve pre-scribed protocol sequences may be stored. The name
of the protocol sequence in the figure above is called Example Protocol. As many protocol sequences as
required may be saved.

Data Logging
Steps to perform data logging
1. Setup the procedure information by clicking the procedure information button and filling in the
resulting screen. If you wish to skip this step the procedure information in the resulting log will be
filled with blank spaces.
2. Click the record data button located in the top left corner of the screen, you will be prompted to
select a save file name and location. By default the name of the save file is the animal name or
identifying reference followed by the current date and time.
3. Approximately once every 4 seconds the current time, control temp, aux temp and error state will
be recorded.
4. Notes can be added using the function keys (Use protocol setup to configure these) and the add
annotation tab.
5. Once the procedure is complete press the stop recording button to end recording.
6. Press the ‘export to CSV’ option in the file menu to export the recording to two CSV files, one
containing the animals’ information and notes/annotations and the other containing the recorded
data. (If you don’t wish to export immediately previously recorded data can be loaded via the ‘open’
option of the file menu).
7. The CSV files will automatically be opened in Excel if it is loaded on the working computer.

Inspiratory Temperature
For heated breathing tube, the temperature displayed is the temperature measured at the exit of the tube.
The temperature probe primarily measures heat from direct conduction from the tube.
The delivered gas temperature to the top of the Endo-tracheal tube will NOT be the same as the inspired
heating tube temperature. Energy (and hence temperature) will be lost due to:a) Specific heat capacity of the gas and the efficiency of energy transfer into the gas
b) Gas mixing (inspired / expired) at the Y piece
c) Gas flow rates and turbulence (Reynolds Number)
By experimentation it has been found that the temperature offset (loss) between the tube measured
temperature and the Endo-tracheal tube can be 8 – 10C in low flow anaesthesia. Thus a 45C tube
measurement might actually deliver 38C
As a guide, a temperature offset value may be entered in controller set up window. If this offset value is not
zero, then the Estimated Endo-Tracheal temperature will be displayed on a number box on the top right
hand side of the chart area.

Software and Controller Firmware Update
“HBC software” refers to the Windows based software running on your computer whereas the firmware is
stand-alone software running on a microprocessor inside the Heated Breathing Controller unit.
From time to time both Software and Firmware improvements may be available as updates.
There are four update methods:1) Automated updates (Software and Firmware) – Only if the computer has a live internet connection:
When the HBC program is started and an HBC controller is connected to the USB port the program
will check the versions of the software and firmware being used against out update website
(www.aasmedical.net ). If updates are available, the program will guide the user through the
process. Note that automatic updates can be turned off. (Menu Setup…. Preferences)
2) Selected Updates (Software and Firmware) - In (Menu Help …. Check for updates guides)..the user
through the same update process as 1), however it is user triggered
3) Manual update (Firmware only) - (Menu Setup…. Preferences)- resets the controller. The user should
manually start the upgrade program which must be installed in ( “MyDirectory/AAS/HBC”). The
latest version is available from www.aasmedical.net/HBC.
4) Manual update (Software only) – download the latest version from www.aasmedical.net/HBC and
run directly as a windows installation.
If during the upgrade of firmware process a popup as seen in Figure 5 appears, the Windows operating
system has not yet registered the upgrade programmer (bootloader) yet. Please wait for 30 seconds and
click OK as instructed.
Figure 5 Unable to open USB device - during upgrade of firmware
Once downloaded your HBC device will be reset into boot loader mode and the boot loader software
(Figure 6) will be launched.

Select ‘program’ from the program menu to update your device, DO NOT remove the device or switch
off your computer during this process. Once the update is completed your device will be reset (Note: if
the device is not reset or you decided not to update, you will be able to get out of programmer mode by
simply resetting your device).
