ENHANCED ARTERIAL OXYGEN SATURATION DETERMINATION AND ARTERIAL BLOOD PRESSURE MONITORING

摘要

a method and system for non-invasive monitor levels of arterial oxygen saturation and the blood pressure. the apparatus includes a light emitting diode) (54) and (56) of the infrared are their respective light beams on a portion of a patient's body so that they are, or are thinking about it.a phototransducteur (64) is positioned to receive the light beams (608, 62) transmitted through the portion of the body. a sleeve (34) to measure the tension surrounding the portion of the body (36) and the dels (54, 56).for calibration, we can apply a pressure on the side of the body (36), and determining the systolic and mean blood, as well as the level of arterial oxygen saturation. the pressure on the side of the body (36) is then released and another arterial oxygen saturation level is determined.the difference between the two levels of oxygen is used as a calibration factor during subsequent periods of control in order to eliminate the effect of arterial oxygen saturation levels, not on the values obtained during the subsequent periods of control the.
