Abstract: A respiration monitor includes a multi-channel respiration sensor including a first electrode that is configured to measure a first capacitance signal transmitted along a first channel and a second electrode that is configured to measure a second capacitance signal transmitted along a second channel. The respiration monitor includes a processor configured to receive the first capacitance signal and the second capacitance signal, compare the first capacitance signal and the second capacitance signal to a respiration threshold, and determine which one of the first capacitance signal or the second capacitance signal is within the respiration threshold. The processor is further configured to, if one of the first capacitance signal or the second capacitance signal is outside of the respiration threshold, extrapolate only the first capacitance signal or the second capacitance signal that is within the respiration threshold to determine a tidal respiration volume.
