Physiological monitor
First Claim
Patent Images
1. A physiological monitor comprising:
- a sensor interface in communication with sensors adapted to be positioned at at least two peripheral tissue sites, said interface having an interface output responsive to light transmitted through said sites; and
a signal processor in communication with said sensor interface output that provides at least one parameter corresponding to oxygen status or plethysmograph features of said at least two sites, said signal processor comparing at least one parameter from each of said at least two sites to determine the presence of a heart abnormality based upon the comparison.

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. A patient monitor uses the signals to determine if there is a heart abnormality.

8. A physiological monitor comprising:
-
at least two sensor interfaces each in communication with at least one sensor adapted to be positioned at one of at least two peripheral tissue sites, each of said interfaces having at least one output responsive to light transmitted through a corresponding one of said sites; and
a signal processor in communication with said sensor interface outputs, said processor having an output comprising at least one parameter corresponding to oxygen status or plethysmograph features of said sites, said signal processors comparing at least one parameter from each of said at least two sites to determine the presence of a heart abnormality. - View Dependent Claims (9, 10, 11, 12, 13, 14)
