摘要： PROBLEM TO BE SOLVED: To provide the diagnostic method of a sleep apnea syndrome capable of diagnosing the sleep apnea syndrome even at home without burdening a patient much. SOLUTION: A data processor extracts and digitizes the feature of pulse wave data detected in a pulse wave sensor and diagnoses the sleep apnea syndrome on the basis of the numerical value. For instance, at the time of paying attention to the envelope of pulse waves, since the amplitude of the fluctuation of the envelope is larger at the time of closed type apnea compared to the time of normal respiration, the closed type apnea is judged when the amplitude of the fluctuation of the envelope becomes the double or more of the value at the time of the normal respiration. Also, at the time of central type apnea, since respiration signals disappear from the envelope by the stoppage of the movement of the chest, the fluctuation of the long cycle of about 10 seconds (about 7 to 12 seconds) appears in the envelope. Thus, for instance, when the fluctuation appears in the envelopes A and B in the cycle of 7 seconds or more, the central type apnea is judged.

摘要： PROBLEM TO BE SOLVED: To provide a device/method for analyzing a pulse which enable accurate analysis of change in the pulse by using a pulse wave which can easily be measured, and to provide a program and a recording medium. SOLUTION: A step 100 measures the pulse wave. A step 110 divides a pulse signal to segments. A step 170 sets the cut off frequency Fc of a first low pass filter for performing complex demodulation analysis of the first time. A step 180 sets the cut off frequency Fc of the first low pass filter to be used for complex demodulation analysis of the first time for performing the second and following analysis. Then, the step 190 for advancing from the step 170 or 180 performs complex demodulation analysis. A step 200 compares the (n-1)-st center frequency Fr with the (n)-th center frequency to decide whether they are coincident. A step 210 performs correcting processing using a second low-pass filter for correcting the error of the obtained arithmetic result.

摘要： PROBLEM TO BE SOLVED: To provide a sleep analyzer, a program and a recording medium, capable of executing easy measurement even in a general home or the like without using a large-scale device such as a sleep polygraphy, and deciding quality of a sleep with an simple index. SOLUTION: At step 100, a pulse wave is measured. At step 110, an pulse interval is found from a (digital-converted) signal from a pulse wave sensor 1. For example, a time that is the interval between a peak of the pulse wave and a peak of the pulse wave is found. At step 120, frequency of the pulse interval is analyzed, and components in a frequency band of 0.15-0.45 Hz are extracted. At step 130, power of the frequency components is integrated to find a sleep quality value (an integration value: an accumulation value). At step 140, the quality of the sleep is decided on the basis of the sleep quality value.

摘要： PROBLEM TO BE SOLVED: To provide an organism abnormality monitoring device, a blood pressure monitoring device, an organism abnormality monitoring method, a blood pressure monitoring method, capable of foreseeing or detecting the blood pressure abnormality of an organism by a pulse wave signal and a program and a recording medium, therefor. SOLUTION: At a step 100, the measurement of a pulse wave is started. At a step 110, frequency analysis is performed on a pulse wave signal as the time series data of the pulse wave to find a C-frequency component showing a fluctuation component of a base line of the pulse wave signal and an A-frequency component showing each pulse wave. At a step 120, the ratio C/A of power of peak (peak value C) of the C-frequency component to power of peak (peak value A) of the A-frequency component is found. At a step 130, it is determined whether the blood pressure is abnormal or not according to whether C/A over is a designated determination value or not. At a step 140, assuming that the occurrence of blood pressure abnormality is determined, it is displayed on a display part 21 or an alarm is given, to thereby give information to the person himself or people around him.
