1. A congential heart disease monitor comprising:

  • a sensor configured to emit optical radiation having a plurality of wavelengths into a tissue site and to detect the optical radiation after attenuation by pulsatile blood flowing within the tissue site;

    a patient monitor configured to drive the sensor, receive a sensor signal corresponding to the detected optical radiation and to generate at least one of a visual output and an audio output responsive to the sensor signal; and

    a digital signal processor within the patient monitor programmed to derive a physiological parameter from sensor data responsive to the sensor signal, wherein the physiological parameter is measured at a baseline tissue site and a comparison tissue site, and wherein at least one of the outputs indicates a potential congenital heart disease condition according to a difference between the physiological parameter measured at the baseline tissue site and the physiological parameter measured at the comparison tissue site.
