An improved oximeter device for the calculation of oxygen saturation in arterial blood is provided. A pair of LED's are positioned to transmit red and infrared light through tissue containing the blood. A photo electric converter is provided to receive the transmitted light and convert it into a electrical signals. The probe can store data directed to various characteristics of the LED's, such as the primary wavelength and a secondary wavelength of the LED and an indication of the amount of crosstalk that can occur in the signals. The correction of any errors resulting from crosstalk plus the calculation of oxygen saturation depending on the various characteristics of the LED's can be effectuated.

A noninvasive device for photoelectrically measuring a property of arterial blood is provided. Light that contacts living tissue with arterial blood is converted into a pair of electrical signals. The electrical signals are processed to provide information of the amplitude of the measured signals and are further processed to produce a final output signal that is substantially a square function of a ratio between the electrical signals representative of the amplitudes.

The object of this invention is to provide an extremely simple device to extract information to distinguish between obstructive apnea and central apnea and which performs this operation automatically based on the extracted information.The device is equipped with analog signal processor 2 for generating pulse wave signals based on light received from a light emitting means and passing through or reflecting off living tissue; pulse wave base line analog signal processor 9 for extracting change components of a base line of the generated pulse wave signal; and master microcomputer 6 for distinguishing between obstructive apnea and central apnea on the basis of the extracted pulse wave base line change components.
摘要:
An oximeter for measuring oxygen saturation in arterial blood includes a light source for projecting light to a body member to be measured, a light responsive circuit for receiving the light which has transmitted through said body member and for generating at least first, second and third signals at three different wavelengths, and a calculator for calculating at least first SaO.sub.2 data using first and second signals and second SaO.sub.2 data using first and third signals. It is detected whether or not a difference between the first and second SaO.sub.2 data is within a predetermined level. When the difference is within the predetermined level, it is assumed that the first and/or second SaO.sub.2 data are valid, but if not, they are assumed as invalid.
