Abstract: A room monitoring system includes a plurality of in-room units. The in-room units collect information relating to a clean or dirty status of a plurality of patient rooms and/or equipment in the rooms. A monitoring station receives clean or dirty status information from the in-room units and determines which rooms are clean, and ready for a patient, which are dirty and in need of cleaning, and which are occupied.

Abstract: A method for patient ID resolution in recordation of patient data acquired by a medical device (10) comprises: receiving patient data from the medical device comprising pre-gap patient data (50) followed in time by a time gap (52) followed in time by post-gap patient data (54); receiving one or more timestamped patient ID entries (56, 58) associated with the received patient data; associating first patient ID information with the pre-gap patient data; and associating second patient ID information with the post-gap patient data; wherein the associating operations are based on the one or more timestamped patient ID entries (56, 58) associated with the patient data.

Abstract: When monitoring physiological parameters (e.g., blood pressure, heart rate, etc.) of a patient, a threshold limit (30) is set (e.g., automatically or manually) and the monitored parameter is continuously compared to the threshold limit, which may be constant or may vary with time. An alarm (36) is triggered if the monitored parameter exceeds the threshold limit at any time, or if the monitored parameter has not reached a target value by the end of a predefined time period by which an administered drug or therapy should have been effective.

Abstract: A patient monitoring station includes a display that displays a plurality of sectors. A controller displays the patient data received from one or more remote medical devices in a corresponding sector of the display. The controller is programmed to collapse one or more sector in response to one of (1) not receiving patient data from the corresponding remote patient monitor or (2) receiving patient data not indicative of a pending patient event or alarm condition; and expand at least sectors that receive patient data indicative of a pending patient event or alarm condition.

Abstract: Medical vital signs (110) are captured, recorded, processed, and a signal quality assessment (160) is computed based on signal waveform components such as slope, amplitude, time to rise, time at peak, and degree to which signal peaks (420) and valleys (430). The signal assessment (160) may be used as a basis for rating the quality (130) of the underlying vital signal, to increase the quality of the signal by removing noisy segments and physiologically impossible peaks (42) and valleys (434), to detect a parameter value (120), to label a waveform (140), or to prompt an alarm (550) to indicate the signal has reached a critical level and issue a warning to the user of the vital data. The signal and the assessment are stored in an indexed, searchable data storage memory (590) from which the signals may be retrieved and displayed (300).

Abstract: A neonatal feeding tube (10) includes electronics and instrumentation for monitoring a neonate and for provides nourishment to the neonate. The tube (10) includes electrodes (20) for sensing ECG signals of the neonate. Thermistors (22, 24, 28, 30) are placed at various points along the tube (10) to measure the neonate's temperature at those points. Breathing effort is measured by calculating a pressure differential at two pressure ports (32, 34). Pulse and SpO2 are measured at a fiber optic window (35). The electrodes (20), a distal electrode (64) and a light source (66) aid in helping a caregiver position the tip (12) of the tube (10) correctly in the stomach of the neonate.

Abstract: Visual renderings of medical events and alarms are generated by a display controller (114) and displayed on a display (42, 42?). The display controller is programmed to receive data indicative of physiological or clinical status versus time of a selected patient from a data store (16, 16?) and detect events and/or alarms. An event object is created for each event/alarm segment, including a bar (72, 74) extending along a time line (88). Each event object is labeled using at least one of color coding, height coding, color intensity coding, and character coding.

Abstract: The present invention relates to the determination of an analyte or multiple analytes in blood using information derived from the differential optical absorption spectra of blood. Specifically, the information is derived from the differential spectra of tissue before and immediately after the volume of blood in the tissue has been changed.

Abstract: The present invention relates to the noninvasive measurement of blood hematocrit and hemoglobin content using differential optical absorption of two or more wavelengths of light during blood volume changes. The method is also useful for noninvasive measurements of other blood analytes, such as glucose, where variations in hematocrit or blood hemoglobin concentration cause errors in the measurement.
