The healthcare for patients with spinal cord injury is burden to subjects and medical staffs and thus it is difficult to continuously monitor the pulse and respiration for a long time and early detect physical deconditioning. In this study, the health condition in a patient was evaluated through the pulse and respiration analysis using a non-conscious monitoring system installed in a bed. The capacitance-sensitive pressure sensor was located under the bed mattress. In a patient with spinal cord injury (55 years old), we successfully measured the pulse and respiration rate for three months and those instabilities through the analysis of those standard deviation and frequency distribution of the output signals. From the results, it is shown that the respiration instability and the pulse rate fluctuation can be detected using the present system. This method appears useful for the health condition monitoring and the alarm for physical deconditioning in the patients.
