Abstract
Techniques for determining a volume of exhaled COas a function of time using side-stream capnography, including obtaining flow dynamics measurements of a subject from a flow sensor; obtaining COconcentration measurements of the subject from a side-stream COmonitor; determining a duration of time (ΔT) for a sample of gas to flow from a reference point to the side-stream COmonitor; synchronizing in time the COconcentration measurement with the flow dynamics measurement, based on the determined ΔT; and determining a volume of COexhaled as a function of time, based on the flow dynamics measurement and the synchronized COconcentration measurement.
