278 – Percent End Tidal CO2 Measurement using C02100C

This Application Note describes how to record percent End-Tidal CO2 (% ETCO2) using a BIOPAC CO2100C Carbon Dioxide Amplifier. The note details subject interface options for high flow without a mask, high flow with a mask, low flow without a mask, and MRI.

When a BIOPAC CO2100C Carbon Dioxide Measurement Amplifier is used in conjunction with the MP150 Data Acquisition System and AcqKnowledge software,┬áit’s easy to perform, real-time, breath-by-breath measurements. The AcqKnowledge software will calculate the peak expired CO2 signal to report percent End-Tidal CO2.

End Tidal CO2

End-Tidal CO2 can also be combined with other pulmonary function measurements when a flow transducer and oxygen measurement amplifier are added to the system.
