I am looking for an end tidal CO2 monitor with a waveform output (analogue or digital) for a research project. It actually needs to measure the CO2 throughout the whole breath hence the need for an output signal, not just an ETCO2 number displayed.
I know there are plenty of models out there but can anyone recommend a cheap one? As, like most, the research project is not well funded. Low cost original or a second hand one will do. I will try the usual second hand outlets.
A freeby that is about to be thrown out will always be accepted. It is not for use on a patient so only needs to work, does not need to be in good condition.
Thanks
Robert
