A wireless intraluminal device (102) and an associated system for treating and diagnosing patients are provided. In one embodiment, the wireless intraluminal device (102) includes a flexible elongate member (158) including a proximal portion (106) and a distal portion (108); a sensor assembly (116) coupled to the distal portion of the flexible elongate member; a cable (117) coupled to the sensor assembly and extending along the flexible elongate member; and a wireless transceiver (252) positioned within the flexible elongate member, wherein the wireless transceiver is in communication with the sensor assembly via the cable. A wireless communication component (104) wirelessly transmits a sensor measurement collected by the sensor assembly to a sensor measurement processing system (132) via a wireless link (150) for physiological data generation at the sensor measurement processing system.

A catastrophe-theoretic approach is provided for predicting an occurrence of an ischemic myocardial event (e.g., acute myocardial infarction) for a human patient based on a time series of monitored vital signs values measured from a patient, and in some instances, for providing advanced notice to clinicians or caregivers when such an ischemic event is forecasted or modifying treatment for the patient, according to the predicted likelihood. In particular, an ischemic heart disease management system is provided for determining a likelihood of near-term future significant myocardial ischemia in persons with coronary artery disease. Embodiments of the disclosure described herein may provide a forecasted risk for future significant myocardial ischemia within a time horizon comprising a future time interval. In one embodiment, the future time interval is from 30 min to approximately 4 hours into the future, and may be dependent on the frequency of vital signs measurements.

A patient monitor can diagnose whether its speaker is blocked, malfunctioning, or at a volume that is too low. For example, the monitor can include a processor that can diagnose the speaker by recording a microphone input signal. The processor can compare the microphone input signal to an expected alarm signal that should be output by the speaker. If the two do not match or reasonably correspond to one another, then the processor may increase the volume of the alarm to determine whether doing so can overcome an obstruction, noise, or potential malfunction. The microphone can again detect the speaker output, and the processor can again make another comparison or analysis of the input with the speaker output. If the speaker output as detected via the microphone is still insufficiently loud, then the patient monitor may output an indication that the speaker has a problem.

An asset tracking system includes a camera adapted to capture images and output signals representative of the images. The camera may include one or more depth sensors that detect distances between the depth sensor and objects positioned within the field of view of the one or more cameras. A computer device processes the image signals and or depth signals from cameras and determines any one or more of the following: (a) whether a patient care protocol has been properly followed; (b) what condition a patient is in; (c) whether an infection control protocol has been properly followed; and (d) whether steps have been taken to reduce the risk of a patient from falling. Alerts may be issued if any conditions of importance are detected.

The present invention relates to a method for predicting awakening in a comatose patient based on the progression of auditory discrimination during early stages of coma. EEG measures are acquired from the patient during two distinct periods when said patient is exposed to auditory stimuli comprising repeated standard and deviant sounds. The first period occurs when the comatose patient is in a hypothermia state and the second period occurs when the comatose patient is in a normal temperature state and preferably within 2-3 days from the onset of the coma. The present invention further relates to a computer-implemented method thereof.

The invention provides a physiological probe that comfortably attaches to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe, which comprises a separate cradle module and sensor module, secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. The cradle module, which contains elements subject to wear, is preferably provided as a disposable unit.

A system includes a housing, a capacitive sensor, and an electronics module. The housing has an interior and is configured to be maintained at a first pressure that is lower than a pressure external of the housing the interior under a vacuum pressure. The capacitive sensor is disposed within the housing and includes a plurality of layers of a dielectric material. The electronics module is coupled to the capacitive sensor and includes a processor configured to receive a raw capacitance value from the capacitive sensor and to output a signal identifying a pressure exerted on the capacitive sensor.

The invention is directed to a system and method for providing an ARDS indication of a patient comprising a sampling device for obtaining a gas sample of the exhaled breath of a patient, a measuring unit for measuring a content of n-octane in the exhaled breath of a patient, a controller which is able to distinguish if the patient has or may develop ARDS based on the content of n-octane in the exhaled breath of a patient resulting in a ARDS indication of the patient and provided with a protocol for providing output regarding the ARDS indication of the patient, and a user interface for indicating the ARDS indication to a user.

In one embodiment, a cardio-adaptive non-invasive positive airway pressure device comprises an airflow generator to provide pressurized air to a human. A detector detects a cardiac cycle of the human. A control unit estimates a next cardiac cycle based on the detected cardiac cycle and provides a control signal to the air flow generator to control timing of the providing of the pressurized air to the human based on the estimated cardiac cycle.

The present disclosure provides a system and method of determining a risk score for triage. In particular, a system is provided for providing an assessment of risk of a cardiac event for a patient, for example an incoming patient to a hospital emergency department complaining of chest pain. In the disclosure, the system includes an input device for measuring physiological data based vital signs parameter of the patient, a twelve-lead electrocardiogram (ECG) device for establishing an ECG obtained from results of the electrocardiography procedure, and determining an ECG parameter and a heart rate variability (HRV) parameter therefrom. An ensemble-based scoring system is further provided, establishing weighted classifier based on past patient data and where the vital signs parameter, the ECG parameter and the HRV parameter are compared to corresponding weighted classifiers to determine a risk score. A corresponding method to determine a risk score for triage is also provided.
