Congenital heart disease monitor
First Claim
1. An electronic monitor for detection of congenital heart disease, the electronic monitor comprising one or more hardware processors configured to:
- determine a first oxygen saturation corresponding to a first measurement site on a patient;
determine a second oxygen saturation corresponding to a second measurement site on the patient;
determine a difference between the first oxygen saturation and the second oxygen saturation;
determine a rate of change of the difference between the first oxygen saturation and the second oxygen saturation; and
generate an indicator for display, wherein the indicator is generated based on an application of;
same channel rules on the first saturation value at the first measurement site or the second saturation value at the second measurement site, andcross-channel rules on the difference and the rate of change of the difference, andwherein the indicator corresponds to the detection of congenital heart disease.

Abstract
A congenital heart disease monitor utilizes a sensor capable of emitting multiple wavelengths of optical radiation into a tissue site and detecting the optical radiation after attenuation by pulsatile blood flowing within the tissue site. A patient monitor is capable of receiving a sensor signal corresponding to the detected optical radiation and calculating at least one physiological parameter in response. The physiological parameter is measured at a baseline site and a comparison site and a difference in these measurements is calculated. A potential congenital heart disease condition in indicated according to the measured physiological parameter at each of the sites or the calculated difference in the measured physiological parameter between the sites or both.
