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.

摘要： 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.

摘要： A digital oximeter for noninvasively measuring oxygen saturation of the arterial blood is provided. Photoelectric transducers measure the light intensity after passing through living tissue to produce at least a pair of output signals of different wavelengths of light. A sample hold circuit is provided for correspondingly storing each of the respective output signals. A microprocessor controlled pulse activates a subsequent subtraction step between a second measurement taken for each of the respective wavelengths to correspondingly produce at least a first and second subtraction output. The circuit can then process at least the first and second stored light outputs and the first and second subtraction outputs to indicate the oxygen saturation.
