| 20080221411 | System and method for tissue hydration estimation - A system and method are provided for determining tissue hydration. The method includes transmitting electromagnetic radiation at tissue and detecting the absorption spectrum of the tissue using a spectrum analyzer located in a sensor. Further, the method includes providing a signal correlative to the absorption spectrum from the spectrum analyzer to a monitor and processing the signal to determine an amount of water content in the tissue. | 09-11-2008 |
| 20090216096 | METHOD AND APPARATUS TO DETERMINE SKIN STEROL LEVELS - A method and apparatus is provided for measuring a sterol, such as cholesterol, deposited in the skin. Light of two or more wavelengths is emitted toward or into a skin sample and the light is differentially absorbed by the sterol in the skin sample. The differentially absorbed light is detected and the amount of sterol in the skin sample is determined based on the differential absorption. | 08-27-2009 |
| 20090240126 | Method And System For Classification of Photo-Plethysmographically Detected Respiratory Effort - Embodiments disclosed herein may include systems and methods for determining a patient's respiratory effort and blood oxygen saturation based on data acquired from a pulse oximetry sensor and analyzing the parameters in conjunction with each other. For example, the respiratory effort may be determined based on a photo-plethysmographic waveform generated from light attenuation detected by the sensor, and the blood oxygen saturation may be a pulse-based estimate of arterial blood oxygen saturation determined from the detected attenuation. Analysis of the parameters may enable detection and classification of apnea (e.g., obstructive or central) or another underlying cause for respiratory instability. Furthermore, the measured respiratory effort may be compared to respiratory effort supplied by a ventilator to ensure proper sensor placement before enabling automatic adjustment of ventilator settings. | 09-24-2009 |
| 20090246797 | MEDICAL DEVICE FOR THE ASSESSMENT OF INTERNAL ORGAN TISSUE AND TECHNIQUE FOR USING THE SAME - A system for tissue ischemia detection is provided that may be used to assess markers of tissue ischemia. Such a system may include a sensor that may be used directly on internal tissue to assess ischemic condition. Sensors to be used in conjunction with the provided system may include optical, chemical or electrochemical sensors that may be directly applied or affixed to the tissue, held proximate to the tissue, or spread over the tissue in the form of a gel. | 10-01-2009 |
| 20090247890 | SOLID STATE MYOCARDIAL INFARCTION DETECTOR - The disclosure, according to one embodiment, relates to a breath analyzer device for detecting concentration of a marker, such as pentane, in air exhaled by a patient. The device may include a detector having a solid state sensor able to detect pentane in a concentration of between 1 nmol/l to 5 nmol/l in air exhaled by a patient. The solid state sensor may include a carbon nanotube. The breath analyzer may include a body having a breath detection channel in which the detector is located, a display, and a power source. The disclosure also relates to a method of detecting myocardial infarction in a patient by detecting pentane in exhaled air from the patient. | 10-01-2009 |
