摘要: A method and apparatus for applying infrared radiation to a respiratory gas and detects a signal associated with the quantity of transmitted radiation for measuring the concentration of CO2 in the respiratory gas. The capnometer detects a maximum value of the detection signal from the thermal detector during the present inspiration phase, stores the detected maximum value in RAM, performs the first approximation, Kalman filtering or some other suitable method to compute a corrected value that is valid for the time being until a maximum value is detected in the next inspiration phase, and determines a density signal by calculating the difference between the corrected value and the detection signal.

摘要: In a continuous noninvasive blood pressure measuring apparatus, a systolic pressure, diastolic pressure, and mean arterial pressure for calibration are measured according to the output of a pressure sensor, a cuff pressure is set lower than the diastolic pressure by a cuff pressure control section, and a reference pulse wave is obtained from the arithmetic means of a plurality of cuff pulse waves. A CPU calculates the peak value and the bottom value of the reference pulse wave, and a cuff pressure mean value corresponding to the D.C. component of the reference pulse wave, and further calculates coefficients which are used to allow the peak value, bottom value and cuff pressure mean value thus obtained to correspond to correspond to the systolic pressure, diastolic pressure, and mean arterial pressure, respectively. The CPU calculates according to the output of a temperature sensor a cuff pressure temperature compensation value for compensating for an amount of variation of the cuff pressure which varies with the temperature of the cuff. In addition, the CPU, while compensating the cuff pressure, which is read continuously, with the cuff pressure temperature compensation value, continuously calculates a blood pressure by utilizing the cuff pressure thus compensated, and the coefficients provided by the coefficient calculating section, and the cuff pulse waves read continuously.

摘要: A light emitting portion 3 and a light receiving portion 4 are separately formed, and firmly interposed between tape members 21 and 25 and between tape members 23 and 26, respectively. Those tape members are attached, by sticking, to the opposed locations of a surface of a finger 15 in a state that the optical axes of the light emitting portion 3 and the light receiving portion 4 are coincident with each other. The outer surfaces of them are covered with tape members 25 and 26, whereby the probe is attached to the finger 15.
