distractions that might otherwise be present in one embodiment the analysis module 132 may report a significant discrepancy between the generated waveform and the target waveform that exceeds a pre determined parameter in such a circumstance biofeedback module 106 may provide an intermediate waveform to monitored subject 120 rather than the target waveform in an attempt to incrementally adjust the breathing amplitude of the monitored subject the intermediate waveform in such a situation may represent a more attainable goal to monitored subject 120 and its use may prevent the monitored subject from becoming alarmed which is counter productive over the size of the difference between the generated and target waveforms biofeedback module 106 may provide a number of intermediate waveforms as appropriate for the monitored subject to attempt to replicate in order to incrementally move the monitored subject towards his or her target waveform the embodiments of the present invention thus provide the ability to adjust real time non contact biofeedback based on the subject 39 s actual response to the intervention the non contact monitoring system may use radiated energy e g ultrasonic radio frequency infrared laser etc to identify respiratory waveforms in patients the monitoring system may illuminate a subject in radiated energy and then detect the reflected radiated energy caused by respiratory functions of note.
