Abstract: Methods and systems for detecting and alerting one to a condition of Compartment Syndrome provide for determining concentration data of biochemical compounds in tissues, preferably at a shallow depth beneath the skin; analysing the concentration data to detect a condition of Compartment Syndrome; and triggering an alarm if a condition of Compartment Syndrome is detected. The concentration of biochemical compounds may be measured using Near Infrared Spectroscopy. The biochemical compounds may comprise at least one compound from the group consisting of Hemoglobin, Oxygenated Hemoglobin, Cytochromes and Myoglobin.

Abstract: A system for monitoring urinary system operation comprises a sensor for detecting a level of one or more compounds in tissues of a subject's bladder. A processor identifies a pattern in a time variation of the level detected by the sensor. The processor generates an indicator of bladder function based at least in part on the identified pattern. In some embodiments the processor generates a possible diagnosis based upon the identified pattern and one or more pieces of additional information. The additional information may comprise one or more of: a residual amount of urine after urination; a maximum uroflow rate; and, a delay in onset of urination.
