Forehead sensor placement
First Claim
1. A method for determining a location for the placement of an oximetry sensor, comprising:
- measuring a pulse amplitude using the sensor placed on a location on a body;
comparing the pulse amplitude to a threshold; and
recommending a new sensor location using the monitor if the pulse amplitude is lower than the threshold, wherein the sensor is initially placed on a periphery of the body and wherein the recommending comprises recommending a patient'"'"'s head region.

Abstract
Forehead oximetry sensor devices and methods for determining physiological parameters using forehead oximetry sensors. One method includes placing an oximetry sensor on the forehead of a patient, such that the sensor is placed on the lower forehead region, above the eyebrow with the sensor optics placed lateral of the iris and proximal the temple; and operating the pulse oximeter to obtain the physiological parameter. In one aspect, the method also includes providing and placing a headband over the oximetry sensor, or alternately, the sensor is a headband-integrated sensor. The headband has an elastic segment sized to fit around the patient'"'"'s head. The headband also includes a non-elastic segment that is smaller than and attached with the elastic segment. The non-elastic segment is sized to span a portion of the elastic segment when the elastic segment is stretched. In addition, the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched. When the headband or the headband-integrated sensor is sufficiently tight, it delivers a pressure in the range higher than the venous pressure and lower than the capillary pressure to the forehead of the patient.
