1. A sensor comprising:
- a conformable sensor body having a transmission configuration adapted to be applied to a first tissue site and a reflectance configuration adapted to be applied to a second tissue site;
an emitter and a detector disposed on the sensor body; and
a removable portion of the sensor body indicated by a marker, wherein when the removable portion is associated with the sensor body, the sensor body is in the transmission configuration and when the removable portion is removed from the sensor body, the sensor is in the reflectance configuration.

Abstract
A sensor may be adapted to be placed on multiple tissue sites. A sensor is provided that may have one configuration associated with use on a digit and a second configuration associated with use on another tissue site, such as a forehead. Further, a sensor may be adapted to be a transmission-type sensor or a reflectance-type sensor, depending on its configuration.

20. A sensor comprising:
-
a conformable sensor body having a first configuration adapted to be applied to a first tissue site and a second configuration adapted to be applied to a second tissue site, the first configuration being adapted to measure a first physiological parameter but not a second physiological parameter and the second configuration being adapted to measure a second physiological parameter but not the first physiological parameter; and an emitter and a detector disposed on the sensor body. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A pulse oximetry system comprising:
-
a pulse oximetry monitor; and a sensor adapted to be operatively coupled to the monitor, the sensor comprising; a conformable sensor body having a first configuration adapted to be applied to a first tissue site and a second configuration adapted to be applied to a second tissue site; and an emitter and a detector disposed on the sensor body; a removable portion of the sensor body indicated by a marker, wherein when the removable portion is associated with the sensor body, the sensor body is in the first configuration and when the removable portion is removed from the sensor body, the sensor is in the second configuration; and an indicator adapted to provide an electronic signal to the monitor relating to whether the sensor is in the first configuration or the second configuration. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method of operating a multi-configuration sensor comprising:
-
emitting light into a patient'"'"'s tissue with an emitter disposed on a sensor body the sensor body being capable of a first configuration and a second configuration, the first configuration adapted to be applied to a first tissue site and the second configuration adapted to be applied to a second tissue site, and wherein removal or folding of a portion of the sensor body switches the sensor body from a first configuration to a second configuration; detecting the light with a detector disposed on the sensor body; and providing a signal indicative of a presence or absence of a removable portion of the sensor body. - View Dependent Claims (42, 43)
