1. A sensor comprising:
- an integrated sensor pad having a first portion and a second portion separated by a waist portion, wherein the waist portion is narrower than the first portion and the second portion, and wherein said sensor pad is configured to be adhered to a patient'"'"'s body by an adhesive disposed directly on an underside of said sensor pad;
a light source at least partially housed within said sensor pad and configured to generate near-infrared light and transmit the near-infrared light through part of a patient'"'"'s body; and
a light detector at least partially housed within said sensor pad and configured to detect near-infrared light that has traveled through the part of the patient'"'"'s body, wherein the near-infrared light detected indicates an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled.

Abstract
An exemplary sensor includes a sensor pad having a first portion and a second portion separated by a waist portion. The waist portion is narrower than the first portion and the second portion. A light source that is disposed on the first portion is configured to generate near-infrared light and transmit the near-infrared light through part of a patient'"'"'s body. A light detector that is disposed on the second portion is configured to detect near-infrared light that has traveled through the part of the patient'"'"'s body. The near-infrared light detected indicates an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled.

10. A sensor pad comprising:
-
a first portion configured to house a light source that generates near-infrared light and transmits the near-infrared light through a part of a patient'"'"'s body; a second portion configured to house a light detector that detects near-infrared light after the near-infrared light has traveled through a part of the patient'"'"'s body, wherein the light received indicates oxygen saturation of the part of the patient'"'"'s body through which the light traveled; and a waist portion disposed between the first portion and the second portion, wherein the surface area of the second portion is larger than the surface area of the first portion and the waist portion is narrower than the first portion and the second portion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A sensor comprising:
-
an integrated sensor pad assembly having a plurality of layers having generally the same size and shape and forming a first portion and a second portion separated by a waist portion, wherein the waist portion is narrower than the first portion and the second portion, the second portion including a light blocking material and the waist portion including a flexible material; a light source disposed on the first portion and configured to generate near-infrared light and transmit the near-infrared light through a part of a patient'"'"'s body; a light detector disposed on the second portion and configured to detect near-infrared light that has traveled through part of the patient'"'"'s body to identify an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled, and wherein the second portion substantially prevents the light detector from receiving interfering light; an adhesive disposed directly on the sensor pad; and a liner disposed on the adhesive and defining a slit located near or over the waist portion. - View Dependent Claims (20, 21, 22)
