Respiratory Gas Analysis – Breath-by-breath

AcqKnowledge gas analysis data

Use AcqKnowledge with BIOPAC’s specially-designed O2 and CO2 modules for quick, accurate respiratory gas analysis. For breath-by-breath respiratory gas analysis, it is important to identify the response time of the gas measurement modules.

Because the modules sample the inspired and expired air stream directly from the subject, without a mixing chamber to average the gas concentration levels, the modules are required to track quickly varying concentration levels.

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.

When fully optimized, the O2100C and CO2100C modules can achieve response times on the order of 200ms and can thus track breathing rates approaching 105 BPM. To enhance a modules response time, run the module at a higher air sampling flow rate and use AcqKnowledge to create a summed derivative filter.
