1. A computer-implemented method for detecting onset of a spontaneous breath by a patient coupled to a ventilation system, comprising:
receiving, at a processor, an electromyography (EMG) signal from an EMG sensor disposed on the patient;
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;
individually analyzing, via the processor, each component of the plurality of components to detect an onset of the spontaneous breath by the patient;
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; and
providing, via the processor, a signal to trigger providing breathing support, via the ventilation system, to the patient when it is determined that the onset of the spontaneous breath is occurring to synchronize the breathing support with the onset of the spontaneous breath.
