摘要:
Methods of processing venous oxygen saturation and hematrocrit information in an implantable sensor are provided. In an embodiment a method for collecting data from an implantable multi-wavelength SvO2 sensor having multiple light sources is provided. The method includes receiving a frame signal that indicates a beginning of the light sources being turned on and receiving a light source signal that indicates a light source is on. The output of a photodetector is sampled to measure the intensity of the transmitted light. The process is repeated for each light source to gather intensity measurements that then can be used to generate venous oxygen saturation and hematocrit measurements.
