According to embodiments, a medical sensor may be configured for use on mucosal tissue. Such a sensor may include a portion that facilitate the application of the sensor to the tissue and a portion that includes the optical components of the sensor. The two portions of the sensor may be reversibly coupled to one another. In embodiments, such sensors may be used to determine patient hematocrit.

Medical sensor and technique for using the same

Correction quantities are generated for yielding closer approximations of actual parameters. These are obtained by preliminarily subjecting parametric transducers to pre-selected parametric values and recording the measured values for each transducer in a data table for later use as or in correction quantities. An embodiment includes interpolation relative to data table values closest to the operationally measured parametric value and using the resulting interpolated value as a corrected parametric value. Such interpolations may be performed for two parametric transducers relative to two substances. The resulting corrected parametric values may then be subtracted to obtain a parametric difference. A further embodiment may include using correction quantities of a reference parametric transducer in interpolation calculations for the actual parametric transducers. Similarly, other data table correction recordations such as differences between two measured parameters can be used to modify an operationally measured parametric differential. Reference transducer corrections can be used here as well.

Associated parameter measuring and/or monitoring such as in the evaluation of pressure differences

Apparatus for detecting a dry bearing condition utilizes an ultrasonic transducer which is intermittently pulsed a certain number of times by a microprocessor and associated circuitry. The number of return pulses received by the ultrasonic transducer is detected by the microprocessor and is used to determine whether a dry bearing condition exists.
