1. A patient monitoring sensor, comprising
a communication interface, through which the patient monitoring sensor can communicate with a monitor;
a light-emitting diode (LED) communicatively coupled to the communication interface;
a detector communicatively coupled to the communication interface, wherein the detector is configured to detect light;
a light blocking layer having one or more holes configured to transmit optical signals from the LED or to the detector; and
an at least partially transparent layer of material between the light blocking layer and the LED, and not between the light blocking layer and the detector, on a patient-side of the sensor, the at least partially transparent layer of material having a thickness of from about 0.08 mm to about 1.5 mm to reduce the contact pressure of protruding portions of the LED.
