Abstract: A method includes receiving a pressure signal from a pressure sensor and/or a flow signal from a flow sensor and receiving signals from one or more sensors that measure different physiological parameters from the pressure sensor and the flow sensor. The method includes detecting the onset of the spontaneous breath by the patient based on the pressure signal and/or the flow signal and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the pressure signal and/or the flow signal. The method includes calibrating parameters and thresholds to be utilized in detecting the onset of the spontaneous breath based on the signals. The method includes after calibration, switching to: detecting the onset of the spontaneous breath by the patient based on the signals and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the signals.

Abstract: A computer-implemented method for detecting onset of a spontaneous breath by a patient coupled to a ventilation system includes receiving, at a processor, an electromyography (EMG) signal from an EMG sensor disposed on the patient. The method also includes pre-conditioning, via the processor, the EMG signal to separate the EMG signal into a plurality of components having EMG information utilizing a set of bandpass filters. The method further includes individually analyzing, via the processor, each component of the plurality of components to detect an onset of the spontaneous breath by the patient. The method still further includes determining, via the processor, the onset of the spontaneous breath by the patient is occurring when at least two components of the plurality of components indicate the onset of the spontaneous breath by the patient.
