ABSTRACT:
In accordance with the present invention, a transmittance pulse oximeter sensor having an emitter that is offset from the detector. Offsetting the emitter and detector allows more light to pass through a thin tissue pulsating arterial bed than does a vertically aligned design. The offset between the emitter and the detector increases the effective arterial blood component without increasing artifact. Thus, the arterial blood component strength relative to the artifact strength is increased resulting in an improved signal and an improved pulse oximetry reading. The offset pulse oximetry sensor is especially important in veterinary pulse oximeter applications where it is necessary to monitor small animals whose optimal pulse oximetry location is a thin tissue tongue. The offset pulse oximetry sensor is additionally important in the realm of human medicine where often the optimal position for a pulse oximeter sensor is a thin tissue ear or an infant's thin tissue finger or toe.
