Method and system for monitoring the physiological condition of a patient

A method of monitoring the physiological condition of a patient's body, comprising the steps of:

• obtaining signals representing the mechanical activity and movement of the body from two or more detecting and sensing means not secured to the body and spaced apart from each other;
• removing signals associated with the movements of the body from the obtained signals;
• separating signals possibly associated with cardiac and/or respiratory activity from the obtained signals;
• determining propagation rates of the pulse waves of cardiac and respiration activities by determining the shift of the obtained cardiac and respiration signals;
• comparing the signals representing propagation rates with propagation rate signals obtained from an earlier measurement of the same body;
• removing those signals which are not characteristic of the wave propagation rates of said body;
• determining the cardiac and respiratory rhythm parameters from the remaining signals;
• comparing said parameters with parameters obtained from an earlier measurement of the same body, as well as with predetermined parameters;
• separating and removing parameters which differ from said predetermined parameters;
• storing, displaying and comparing the separated parameters with parameters obtained from said earlier measurements, and
• generating an alarm when one of the parameters exceeds a preset range.
