METHOD FOR USING A NON-INVASIVE CARDIAC AND RESPIRATORY MONITORING SYSTEM
First Claim
1. A method of monitoring the efficacy of medication, comprising:
- providing a subject with a selected medication;
monitoring the subject with a non-invasive respiratory monitoring system, the monitoring system illuminating the subject with radiated energy produced from within a selected wavelength range, detecting a reflection of the radiated energy from a surface that moves as a result of breathing by the subject, and identifying a waveform indicative of a breathing rate of the subject based on the reflection of the radiated energy;
storing the waveform indicative of the breathing rate; and
comparing the stored waveform to a previously designated waveform to determine whether the selected medication caused an unacceptable deviation in the breathing pattern of the subject.

Abstract
A non-invasive monitoring system using radiated energy to identify cardiac and respiratory waveforms in patients is discussed. The monitoring system illuminates a subject in radiated energy and then detects the reflected radiated energy caused by respiratory and/or cardiac functions. The detected reflections are used to plot a two-dimensional waveform. The waveforms represent the rise and fall of a detected signal (the reflected energy) over time and are indicative of the small movements of the patient'"'"'s chest and abdomen that are associated with cardiac and respiratory function. Different implementations of the monitoring system use laser or ultrasonic energy to capture breathing and cardiac waveforms for analysis. The waveforms may be used to diagnose the effectiveness of prescribed sleep medication, perform remote line of sight monitoring from a remote location, identify crying waveforms for babies and infants, identify cardiac waveforms in a non-invasive manner and identify seizure and tremor activity.
