  • Page 3: Intended Use

    Clinical research has demonstrated that 'the concentration of carbon monoxide in end-expired air after breath holding correlates closely with carboxyhaemoglobin concentration' Operation of the ToxCO® is straightforward; a D-piece™ sampling system and face mask sampling modes allow the user to test a patient independent of their consciousness, whilst the ambient sampling mode helps to safeguard the user by alerting them if they are entering areas with high levels of CO.

  • Page 4: Taking A Face Mask Test

    3. Press ‘breath test’ symbol onscreen, 4. To cancel the breath test, press 5. Inhale and hold breath for the pre-set 15 second countdown. 6. A beep will sound during the last three seconds of the countdown. 7. Blow slowly into the mouthpiece, aiming to empty lungs completely. 8. The %COHb and equivalent ppm levels will rise and hold on-screen. 9. The alarm may be muted by pressing 10. When the test is finished will appear at the bottom of the screen. 11. To repeat breath test, press once and repeat steps 5 - 10. 12. To return to the home screen, press 13. Results save automatically in the breath test log however, there is the option to tag a result with a place, patient’s name or ID. To tag a result, press and enter the place/ID/patient’s name and click save 14.

  • Page 5: Ambient Monitoring

    8 hours of inactivity to save power. (The display dims after 5 minutes and turns off after 15 minutes. Ambient monitoring The ambient air can be tested to check for CO in the environment using the ToxCO®, alerting users to high CO levels in the atmosphere. Once switched on the device will start to sample immediately and the real-time reading will be shown on the home screen at all times, updating every second.

  • Page 6: Adjusting Test Thresholds

    4. Press depending on which threshold is to be adjusted. 5. Drag the threshold indicators up or down to the desired concentration; the ppm values for breath testing will adjust automatically with the %COHb. 6. Pressing will save the changes; pressing will abort the changes and return to the previous screen. Enabling/disabling ppm reading The ToxCO® is programmed to only show the %COHB when a breath test is taken however it is possible to also display the reading in ppm. To enable the ppm display, go to the settings and then click on the crossed out ppm icon .The breath test will look like this once the ppm readings have been enabled. To disable the ppm display, go to the settings and then click on the ppm icon . The breath test will look like this...

  • Page 7: Reviewing History

    Reviewing history The ToxCO® will record/log in its history every breath test but also ambient readings when an alarm threshold is triggered for up to 500 readings for 8 hours or until the monitor is switched off. To access the history, press and then either for the breath test log or for the ambient log. Changing date and time Press and then to access the date/time menu. You can then select either d-m-y or m-d-y for the date format and 12h or 24h for the time format. With the 12h format, there is also the option to select between am and pm. Dates and times are then adjusted by selecting the number you wish to change and pressing to decrease/increase. Press to save your settings or to abort changes and return the previous screen. Changing breath-hold time Press and then to access the breath-hold time screen. Changing the breath-hold time is accomplished by pressing to decrease/increase the time in seconds. Press to save your settings or to abort changes and return the previous screen.
