Classification: CPC A  G | IPC A

Claim 0:
1. A side-stream respiration monitoring system, the system comprising:
an analyzer configured to be fluidly connected to a flow sensor that is constructed to be disposed in a respiration flow path; and
a controller associated with the analyzer and configured to:
initiate delivery of a non-patient originated alignment signal generated by a pump of the analyzer and delivered to the flow sensor during a portion of at least one breath cycle when a physiologic event signal cannot be determined from at least one proceeding breath cycle;
determine a respiration flow value and at least a portion of a composition of the respiration flow on a breath-by-breath basis;
temporally associate in a time-domain the respiration flow value and the portion of the composition of the respiration flow associated with the breath-by-breath basis from 1) the determined respiration flow value and the determined portion of the composition of the respiration flow associated with the alignment signal delivered to the flow sensor by the pump of the analyzer during the portion of the at least one breath cycle associated with delivery of the non-patient originated alignment signal when a physiologic event signal cannot be determined from at least one proceeding breath cycle and 2) a respiration flow value and a portion of the composition of the respiration flow associated with a physiologic event when the physiologic event signal is present within a selected number of proceeding breath cycles; and
generate a time-aligned respiration output providing an alignment between the respiration flow value and the portion of the composition from the temporally associated respiration flow value and portion of the composition of the respiration flow.
