Abstract: A medical sensor includes a first set of optical components configured to obtain a first set of signals for determining a first regional oxygen saturation measurement. The first set of optical components includes a first emitter, a first detector separated from the first emitter by a first distance along a first axis, and a second detector separated from the first emitter by a second distance along the first axis, wherein the second distance is greater than the first distance. The sensor also includes a second set of optical components configured to obtain a second set of signals for determining a second regional oxygen saturation measurement. The second set of optical components includes a second emitter and a third detector separated from the second emitter by a third distance along a second axis, different from the first axis.

Abstract: According to various embodiments, a regional oximetry sensor may include a light emitting element configured to emit light, a light detector configured to receive the light and generate a signal based on the received light. The regional oximetry sensor, itself or in conjunction with a monitor, may enable communicating adjustments in the administration of CPR to a patient based on one or more characteristics (e.g., pulse amplitude or pulse rate) of the signal generated by the regional oximetry sensor.

Abstract: A method and system for regulating contact pressure of a sensor is provided. In accordance with an embodiment, a sensor includes a collapsible material capable of regulating the localized component contact pressure exerted on a tissue between a threshold which ensures proper contact between the sensing component and monitoring site but which minimizes incidents of excessive localized pressures which could result in tissue damage over prolonged use. This localized contact pressure range is maintained over a wide range of sensor application pressures. In one embodiment, a window is provided in the sensor and a colorimetric indication of the compression or expansion of the collapsible material may be determined through the window.

Abstract: A physiological sensor includes an emitter configured to transmit light and a detector configured to receive the transmitted light. The sensor also includes a first accelerometer disposed on a first portion of the sensor and a second accelerometer disposed on a second portion of the sensor, the second portion opposing the first portion. The first and second accelerometers are configured to measure a change in motion that corresponds to a change in distance between the detector and the emitter.

Abstract: Devices and methods for determining the fluid characteristics of a blood sample may include the assessment of a pressure waveform of a fluid sample having a pre-determined volume passed through or out of a flow restrictor. The interface between the blood and other fluids in the tubing line of the blood monitoring system may also be assessed. These assessments may be used alone or in combination to generate estimates of other fluid characteristics, such as the hematocrit of a blood sample. This information may be used for the real-time determination of change of hematocrit levels in a patient's blood while the patient is being transfused with intravenous fluids or other vascular products, or to provide adjustment factors for other blood assays affected by the hematocrit or other blood parameters.

Abstract: The present invention is directed towards apparatuses and methods for the automated measurement of blood analytes and blood parameters for bedside monitoring of patient blood chemistry. Particularly, the current invention discloses a programmable system that can automatically draw blood samples at a suitable programmable time frequency (or at predetermined timing), can automatically analyze the drawn blood samples and immediately measure and display blood parameters such as glucose levels, hematocrit levels, hemoglobin blood oxygen saturation, blood gases, lactate or any other blood parameter.
