Abstract: A patient monitor for monitoring a patient's orientation to reduce a risk of the patient developing a pressure ulcer can include one or more hardware processors that can receive and process data from a sensor to determine the patient's orientation. The one or more hardware processors can maintain a plurality of timers associated with available orientations of the patient. Each of the plurality of timers can account for a non-consecutive duration said patient is in an associated available orientation. The non-consecutive duration can vary depending on whether a patient is in the available orientation. The patient monitor can include a structured display including an orientation trend and a patient representation illustrating a current orientation of the patient. The orientation trend can include a heat map that graphically illustrates said non-consecutive durations of the patient in the available orientations and/or an orientation graph that displays the patient' orientation history.

Abstract: An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service.

Abstract: An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information indicates a non-distress stats and notifies a second set of contact when the opioid monitoring information indicates an overdose event. The notification can be a phone call or text message to a specified person, emergency personnel, or first responders, and can include the location of the smart mobile device. The smart mobile device can also include the location of the nearest treatment center having emergency medication used in treating opioid overdose, such as naloxone.

Abstract: This disclosure describes example alarm notification systems that can enable a clinician to respond to an alarm notification received via a computing device, which may have more advanced functionality than a pager. The clinician device may be a mobile device, such as a cellphone or smartphone, tablet, laptop, personal digital assistant (PDA), or the like. The clinician device may communicate with a remote server to obtain patient data generated by a patient device at the point-of-care (such as a bedside device or patient-worn monitor). This patient data may be continuous monitoring data for one or more patients. A mobile application (optionally a browser application) on the clinician device can enable the clinician to view continuous monitoring data for multiple patients, as well as view and respond to alarms and alerts, all from the clinician device, regardless of location.

Abstract: A patient monitoring system can have a display screen or portion thereof with graphic user interface for displaying indications of a patient's oxygen state. The indications can include the patient's SpO2, dissolved oxygen index, and/or an increasing or decreasing trend of dissolved oxygen index. The displays of oxygen state indications can be compact, and/or able to provide direct visual information to a user of various aspects of the patient's oxygen state. The display elements can be used to represent any other physiological parameters.

Abstract: A lap shear test fixture and method of use to test the performance of the weld interface in welded thermoplastic composite parts such as infrared welded or resistive implant welded or adhesive bonded composite parts. The specimens to be tested are provided from production-ready parts with typical geometry. The test fixture has at least two aligned blocks with at least two lateral support blocks that operably hold the specimen including two welded substrates. The test is performed in compression-mode at a pre-determined crosshead speed until the maximum load produced by a universal testing machine makes the weld interface between the two thermoplastic substrates fail in shear mode.

Abstract: A total hemoglobin index system derives total hemoglobin (tHb) index value utilizing a depopulated emitter with an index set of LEDs. A patient fails a tHb index test if tHb measurements are trending down and/or tHb values fall below a predefined index threshold. If a patient fails the tHb index test, a high resolution sensor derives a specific tHb measurement utilizing a high resolution set of LEDs. The number of high resolution set LEDs is greater than the number of index set LEDs.

Abstract: The present disclosure includes a host device that is part of a patient monitoring system. The host device can provide an improved, organized, uncluttered, and graphically-rich display that presents an integrated display of real-time patient data and alarms from multiple integrated or non-integrated devices, such as patient monitors, ventilators, anesthesia gas machines, or intravenous (IV) pumps. The host device may provide a supplementary display for the patient data collected by the multiple devices and present information, such as comprehensive real-time patient status, historical trends, or alarm indicators, in an organized manner for particular clinical scenarios. The one or more displays can be central to a care team for a patient, and the care team can together simultaneously view and act upon the information presented.

Abstract: A regional oximetry system has a display and at least one processor causing a plurality of views to be displayed on the display, each configured to occupy at least a portion of the display. The views are adapted to present data responsive to at least one physiological signal. A first sensor port is configured to receive at least a first physiological signal representative of a regional tissue oxygenation level, and a second sensor port is configured to receive at least a second physiological signal representative of an arterial oxygen saturation level. One view presents a first trend graph of the first physiological signal and a second trend graph of the second physiological signal. An area between the first trend graph and the second trend graph can include a differential analysis of regional-to-central oxygen saturation.

Abstract: A portable spot-check system configured to assess the validity of a measured physiological parameter. The spot-check device can take into consideration a variety of factors to determine whether a valid measurement exists. For instance, the considerations can include signal stability, interference, signal IQ, patient movement, sensor position, timing of that measurement, comparison to previous or acceptable measurements, cancellation of measurement by the patient, confidence of the measurement, etc. The spot-check device can track a number of valid measurements. In some instances, the spot-check device is configured to provide a specified number of available measurements. If a valid measurement is recorded, the spot-check device can decrement the remaining number of available measurements.

Abstract: A device for obtaining physiological information including plethysmographs of a medical patient and detecting a condition of pneumonia. The portable pneumonia screening device may include one or more sensors configured to obtain physiological information.
