The present disclosure relates to a sensor for monitoring the depth of consciousness of a patient. The sensor includes a plurality of light sources, light detectors, and in some embodiments, electrodes. In an embodiment, the sensor includes reusable and disposable portions.

A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

A method includes receiving from a psychological and physiological sensing (PPS) device worn on a subject's head, sensor data from sensors fixed to the PPS device. The sensors may include a left-temple photoplethysmography (PPG) sensor, a right-temple PPG sensor, and an electroencephalogram (EEG) sensor coupled to the subject's head. The right and left temple PPG sensors are configured to detect pulsating blood flow in blood vessels proximal to a left and right temple region. Pulse morphology data of pulses related to the pulsating blood flow from the left-temple PPG signal and the right-temple PPG signal are determined. A possibility of a cardiac dysfunction, a cerebral dysfunction, or both in the subject may be determined based on an EEG signal, a comparison of the pulse morphology data of pulses from the left-temple PPG signal and the right-temple PPG signal, or both.

The clinical diagnosis and monitoring of patients with neurological conditions may be established through behavioral examinations, assessments or evaluations, or neuroimaging scans. The system and methods described herein diagnose the cognitive function of a subject by measuring the neural response of the subject to one or more naturalistic sensory stimuli. The system measures the subject's sensory evoked response to the naturalistic sensory stimuli by computing the statistical comparison between the subject's neural signal and either the raw stimulus signal or the stimulus' signal envelope. A latency value, or other signal feature, is extracted from the subject's sensory evoked response and a diagnosis of the subject's cognitive function is then made based on the identified latency value or other extracted signal feature.

A non-invasive, optical-based physiological monitoring system is disclosed. In an embodiment, the non-invasive, optical-based physiological monitoring system comprises an emitter configured to emit light into a tissue site of a living patient; a detector configured to detect the emitted light after attenuation by the tissue site and output a sensor signal responsive to the detected light; and a processor configured to determine, based on the sensor signal, a first physiological parameter indicative of a level of pain of the patient.

The present disclosure includes a medical monitoring hub as the center of monitoring for a monitored patient. The hub includes configurable medical ports and serial ports for communicating with other medical devices in the patient's proximity. Moreover, the hub communicates with a portable patient monitor. The monitor, when docked with the hub provides display graphics different from when undocked, the display graphics including anatomical information. The hub assembles the often vast amount of electronic medical data, associates it with the monitored patient, and in some embodiments, communicates the data to the patient's medical records.

A method, system and computer-readable medium are provided for determining compliance with patient care protocols, comprising an infusion pump providing infusion information pertaining to one or more drugs administered to a patient, the one or more drugs including sedatives and analgesics, and a processor communicably coupled to the infusion pump and configured to determine information regarding the one or more drugs being administered to the patient based on the infusion information by determining a baseline threshold for the one or more drugs being administered to the patient according to the actual dosage of the one or more drugs administered to the patient prior to a current time, determining a dosage amount of the one or more drugs currently being administered to the patient and comparing the dosage amount of the one or more drugs currently being administered to the baseline threshold to determine a deviation from the baseline threshold.

A patient monitoring system may include processing circuitry configured to receive an indication of a surgical event, obtain a nociception parameter of a patient, compare the nociception parameter of the patient to a nociception threshold to detect a nociception event, determine whether the surgical event corresponds to the nociception event, and in response to determinizing whether the surgical event corresponds to the nociception event, provide an indication to adjust an amount of analgesic administered to the patient.

An acoustic sensor platform based method and apparatus provides for improved pain mitigation, apnea detection, aspiration detection and patient communication in anesthesia patients. The platform includes an acoustic sensor configured to be coupled to one of a nasal cannula or face mask of the anesthesia patient; a processer coupled to the acoustic sensor and configured to i) Detect patient speech and isolate and amplify the patient speech, and ii) Detect at least one of a breathing rate of the patient or aspiration of the patient; and an audio visual display coupled to the processor and providing an audio and/or visual display of the isolated and amplified speech of the patient, and displaying results for at least one of a breathing rate of the patient or aspiration of the patient.

Electrodes for use in electroencephalographic recording, including consciousness and seizure monitoring applications, have novel features that speed, facilitate or enforce proper placement of the electrodes, including any of alignment indicators, tabs and juts, color coding, and an insulating bridge between reference and ground electrodes which ensures a safe application distance between the conductive regions of the two electrodes in the event of cardiac defibrillation. A method of using a set of at least four such electrodes is also disclosed.
