1. A computer-implemented method for determining the existence of a critical congenital heart defect, the computer-implemented method comprising:
- under control of one or more computing devices configured with specific computer executable instructions,gathering first physiological data from a first site on a patient'"'"'s body for a first period of time;
gathering second physiological data from a second site on a patient'"'"'s body for a second period of time;
processing said first physiological data and said second physiological data, wherein said processing comprises at least;
selecting at least a first sub-portion of at least one of said first physiological data or said second physiological data based on one or more confidence criteria;
selecting at least a second sub-portion of an other of said first physiological data or said second physiological data; and
comparing the first sub-portion to the second sub-portion to determine a difference; and
outputting the difference, the difference used to determine the existence of a critical congenital heart defect.

Abstract
Automated critical congenital heart defect (“CCHD”) screening systems and processes are described. A caregiver may be guided to use a single or dual sensor pulse oximeter to obtain pre- and post-ductal blood oxygenation measurements. A delta of the measurements indicates the possible existence or nonexistence of a CCHD. Errors in the measurements are reduced by a configurable measurement confidence threshold based on, for example, a perfusion index. Measurement data may be stored and retrieved from a remote data processing center for repeated screenings.

9. A system configured to indicate the existence of a critical congenital heart defect, the system comprising:
-
a noninvasive sensor configured to gather blood oxygen saturation data related to a patient; and a pulse oximeter in communication with the noninvasive sensor, the pulse oximeter configured to process the blood oxygen saturation data, wherein blood oxygen saturation data related to the patient is gathered from a first site for a first period of time and a second site for a second period of time with the noninvasive sensor, wherein at least a first sub-portion of blood oxygen saturation data from at least one of the first site or the second site is selected based on one or more confidence criteria, wherein at least a second sub-portion blood oxygen saturation data from an other of the first site or the second site is selected, wherein the first sub-portion is compared to the second sub-portion to compute a delta, and wherein the computed delta indicates the existence or nonexistence of a critical congenital heart defect. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system configured to indicate the existence of a critical congenital heart defect, the system comprising:
-
a plurality of noninvasive sensors configured to gather blood oxygen saturation data related to a patient; and a pulse oximeter in communication with the plurality of noninvasive sensors, the pulse oximeter configured to process the blood oxygen saturation data, wherein blood oxygen saturation data related to the patient is gathered from at least a first site and a second site simultaneously for a period of time with two or more of the plurality of noninvasive sensors, wherein at least a first sub-portion of blood oxygen saturation data from at least one of the first site or the second site is selected based on one or more confidence criteria, wherein at least a second sub-portion of blood oxygen saturation data from an other of the first site or the second site is selected, wherein the first sub-portion is compared to the second sub-portion to compute a delta, and wherein the computed delta indicates the existence or nonexistence of a critical congenital heart defect. - View Dependent Claims (20, 21, 22, 23)
