ToxCO® CO Monitor

Quick, easy & non-invasive screening for CO poisoning

The ToxCO® is a carbon monoxide (CO) breath analyser to screen for CO poisoning. An ideal tool for emergency services and first responders, the ToxCO® is a quick, easy, reliable and completely non-invasive way to screen for CO poisoning.
ToxCO® CO Monitor

Why ToxCO®?

The ToxCO® is an easy to use, non-invasive breath and ambient air CO monitor, with three sampling modes, enabling breath samples to be taken from patients of any age or consciousness, and the monitoring of ambient levels to alert staff of potentially fatal levels of CO in the air. 

Why is it important?

Clinical research has demonstrated that 'the concentration of carbon monoxide in end expired air after breath holding correlates closely with carboxyhaemoglobin concentration'1.

With the ToxCO®, the mouthpiece and facemask sampling modes allow the user to test a patient independent of their consciousness, whilst the ambient sampling mode will safeguard the user, alerting them if they are entering area with high levels of CO.

The ToxCO® helps to reduce unnecessary hospital admissions through instant screening but also helps to save the lives of your patients and your staff, one breath at a time.

Benefits to the user

The monitor provides instant results shown in %COHb which makes interpreting patient’s results quick and easy.
The colour touchscreen is quick and easy use, with visual prompts for patients during each test to ensure correct results every time.
There is automatic calibration and D-piece™ renewal reminders to prolong the life of your monitor, ensure accurate readings and increase infection control.
The monitor has built in SteriTouch® technology for improved infection control.
D-pieces are used in conjunction with the monitor to filter out 99.9% of airborne bacteria and single-use Steribreath™ mouthpieces for excellent, low cost infection control.2
The ToxCO® will automatically log every breath test but also ambient readings when an alarm threshold is triggered for up to 500 readings.
There is also the option to tag a result with a place, patient’s name or ID. 
5 years warranty (subject to service & maintenance plan).

SteriBreath™ mouthpieces

SteriBreath™ mouthpieces for use with Bedfont® breath analysis monitors, combining ease of use with optimum infection control.


The D-piece™ incorporates a one-way valve to prevent air being drawn back from the monitor. The breath then passes through an infection control filter, proven to remove and trap >99.9% of airborne bacteria.

Face mask sampling system

This sampling system is single patent use and allows the patient to breathe normally through a face mask in order to produce a breath sample. The facemask is available in three different sizes: infant, medium and adult.

Monitor cleaning wipes

Free from alcohol, ensuring the continued performance of your monitor. Pack contains 50 wipes.
