    Abstract: A sensor may be placed on a distal portion of a patient's finger or toe to obtain pulse oximetry measurements. The distal portion of a digit contains few if any large vascular structures that could adversely affect pulse oximetry measurements, but the distal portion does contain microvasculature that carries arterial blood that facilitates pulse oximetry measurements. The sensor may include an emitter and a detector that are spaced apart by an appropriate distance so that they may be located on the distal portion of a patient's digit during pulse oximetry measurements.

    Abstract: A method and apparatus for reducing cross-talk in an oximeter. The oximeter includes a band pass filter. The amount of cross-talk through the band pass filter is estimated. Based on this estimate, the corner frequencies of the band pass filter are adjusted when it is designed to minimize the cross-talk. In one embodiment, a calibration mode is performed when a sensor is attached to the oximeter. In the calibration mode, the signals are measured with first only the red LED on and then with only the IR LED on. Any signal measured in the off channel is assumed to be a result of cross-talk from the other channel. The magnitude of the cross-talk is determined as a percentage, and subsequently the percentage is multiplied by the actual signal and subtracted from the other LED signal as cross-talk compensation.

    Abstract: Low power techniques for sensing cardiac pulses in a signal from a sensor (101) are provided. A pulse detection block (102) senses the sensor signal and determines its signal-to-noise ratio. After comparing the signal-to-noise ratio to a threshold, the drive current of light emitting elements in the sensor is dynamically adjusted to reduce power consumption while maintaining the signal-to-noise ratio at an adequate level. The signal component of the sensor signal can be measured by identifying systolic transitions. The systolic transitions are detected using a maximum and minimum derivative averaging scheme. The moving minimum (301) and the moving maximum (304) are compared to the scaled sum (312, 313) of the moving minimum and moving maximum to identify the systolic transitions. Once the signal component has been identified, the signal component is compared to a noise component to calculate the signal-to-noise ratio.

    Abstract: A presenting part fetal pulse oximeter sensor which does not penetrate the fetus' skin, and does not rely on a vacuum for attachment is provided. The fetal sensor (10) of the present invention is held in place by pressure applied to the fetus by a number of different mechanisms. In one embodiment, the sensor is held in place against the fetus by a rigid rod (12), with the pressure being applied by the physician or technican's hand on the rod. This type of sensor is useful for spot-checking, where continuous monitoring is not needed. In another embodiment, a pre-loaded spring (24) is coupled between the rod and the sensor head to prevent too much pressure being applied by the user.

    Abstract: A fetal pulse oximeter sensor in which a sensor head (10) is held against the fetus (14) by the action of a securing means (20, 24) which is remote from the sensor head. The securing means is sufficiently remote so that light detected by the light detector (48) in the sensor head does not scatter through tissue which may be deformed by the securing mechanism. The securing mechanism could deform the tissue by applying pressure, to exanguinate the tissue, or could attach to the tissue by vacuum, penetration, or glue, etc.
