1. A physiological monitor comprising:

  • interface componentry in communication with at least two sensors adapted to be positioned on tissue sites of a patient, the interface componentry having at least two outputs corresponding to signals received from the at least two sensors and responsive to light transmitted through corresponding tissue sites; and

    at least one signal processor in communication with the interface componentry outputs, the at least one signal processor configured to;

    receive a first output, from the interface componentry, associated with a first tissue site of a first limb of the patient;

    receive a second output, from the interface componentry, associated with a second tissue site on a second limb of the patient;

    determine at least one first oxygen saturation measurement from the first tissue site and at least one second oxygen saturation measurement from the second tissue site in response to the first output and the second output;

    determine the presence of a heart abnormality of an infant based at least in part on a comparison of the at least one first oxygen saturation measurement with the at least one second oxygen saturation; and

    display an indication of the heart abnormality.
