Abstract

A regional oximetry pod drives optical emitters on regional oximetry sensors and receives the corresponding detector signals in response. The sensor pod has a dual sensor connector configured to physically attach and electrically connect one or two regional oximetry sensors. The pod housing has a first housing end and a second housing end. The dual sensor connector is disposed proximate the first housing end. The housing at least partially encloses the dual sensor connector. A monitor connector is disposed proximate a second housing end. An analog board is disposed within the pod housing and is in communications with the dual sensor connector. A digital board is disposed within the pod housing in communications with the monitor connector.
