First Claim
Patent Images
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.

Abstract
A patient monitor has multiple sensors adapted to attach to tissue sites of a living subject. The sensors generate sensor signals that are responsive to at least two wavelengths of optical radiation after attenuation by pulsatile blood within the tissue sites.

9. A method for determining a heart abnormality in an infant, the method comprising:
-
using a pulse oximeter to determine a first oxygen saturation measurement from a first tissue site on a first limb of a patient; using the pulse oximeter to determine a second oxygen saturation measurement from at least one additional tissue site on a second limb of the patient; determining the presence of a heart abnormality of an infant based at least in part on a comparison of the first oxygen saturation measurement with the second oxygen saturation measurement; and determining and displaying an indication of the heart abnormality on a display device of the pulse oximeter. - View Dependent Claims (10, 11, 12, 13, 14, 15)
