An apparatus and method for detecting patient inspiration is provided. It includes means for providing a baseline level for the patient's respiration signal and for establishing a trigger level representative of inspiration. When the respiration signal crosses the trigger level for selected crossovers inspiration trigger signals are generated. Most importantly means are provided for automatically detecting shifts in the baseline level and for re-establishing the trigger level for the shifted waveform. In the preferred embodiment the apparatus is capable of detecting a baseline shift in about one cycle of the respiration waveform. The apparatus and method further provides for an inspiration detector with adjustable detection characteristics to accommodate both adult and neonate patients.
