A device for the determination of at least one compression parameter during administration of cardiopulmonary resuscitation (CPR) on a patient comprising: a field generator, a field detector, and a processor. Position information and the compression parameter are determined from the field detected by the field detector. One of the field generator and the field detector is a position sensor and the other is a reference sensor.

A chest compression monitor for measuring the depth of chest compressions achieved during CPR. A displacement detector produces a displacement signal indicative of the displacement of the CPR recipient's chest toward the recipient's spine. A signaling mechanism provides chest compression indication signals prompting a CPR provider to provide a chest compression force at a desired depth and rate. The device is held to the dorsal surface of the hand during use and provides a display for feedback, which is readily visible to the CPR provider.

A system for determining T wave bifurcation that includes three or more ECG leads configured to receive an ECG signal and a first computing device including a processor coupled to a memory, the processor and the memory configured to perform operations including: generating at least two orthogonal ECG vectors based on the ECG signal of a patient, processing the at least two orthogonal ECG vectors to determine a loop trajectory of at least a portion of the ECG signal, identifying a trajectory bifurcation by comparing the loop trajectory to a control loop trajectory for a plurality of cardiac cycles, and determining an indicator of a cardiac event based on the trajectory bifurcation.

A wearable cardioverter defibrillator (WCD) system includes a support structure that the patient may wear, and one or more sensors that may acquire patient physiological signals, such as ECG and others. A processor of the WCD system may determine diagnostics from the patient physiological signals. These diagnostics include a six-second ECG portion, heart rates as histograms, heart rates against QRS width, heart rate trends, clinical event counters, diagnostics relating to heart rate variability and about the atrial arrhythmia burden of the patient. In some embodiments, the WCD system includes a user interface with a screen that displays these diagnostics. In some embodiments, the WCD system exports these diagnostics for viewing by a different screen. When viewed, these diagnostics permit more detailed analysis of the state of the patient.

Methods and systems that analyze electrocardiogram (ECG) data to identify whether it would be beneficial for a caregiver to administer an electric shock to the heart in an effort to get the heart back into a normal pattern and a consistent, strong beat. By conducting a running check for conditions that are pre-validated by a comprehensive patient database to have high predictive value (e.g., with a low false-positive rate), a shockable rhythm can be identified fast (e.g., less than 6 seconds, less than 3 seconds, possibly in less than a second) and without having to analyze ECG data for longer time segments than would otherwise be required using conventional methods.

A system and a method for automatically and continuously measuring and assessing hemodynamics uses fluorescence imaging in which the fluorescent agent is controlled and automated. A method of automatic perfusion assessment of an anatomical structure of a subject includes administration into a vein of a bolus corresponding to less than 0.01 mg ICG/kg body weight of a first fluorescence imaging agent. A system for automatic perfusion assessment during a medical procedure includes a controllable injection pump for holding at least one first fluorescence imaging agent, the injection pump being configured for injecting a predefined amount of the first fluorescence imaging agent into the blood. The system is configured for receiving and analysing a time series of fluorescence images and determining at least one perfusion parameter based on the analysis.

The temperature sensor is coupled to the processing unit, wherein the temperature sensor is adapted to send a temperature sensing signal to the processing unit. The touch sensor is coupled to the processing unit, wherein the touch sensor is adapted to send a touch sensing signal to the processing unit. The signal transmitting unit is coupled to the processing unit, wherein the processing unit controls the signal transmitting unit to send an emergency signal according to the temperature sensing signal and the touch sensing signal.

The present disclosure describes a closed-loop fluid resuscitation and/or cardiovascular drug administration system that uses continuous measurements and adaptive control architecture. The adaptive control architecture uses a function approximator to identify unknown dynamics and physiological parameters of a patient to compute appropriate infusion rates and to regulate the endpoint of resuscitation.

Various systems, devices, and methods are disclosed herein for treating acute myocardial infarction (AMI) patients using a heart pump controlled in a manner that maximizes mechanical unloading of the left ventricle in the presence of cardiovascular instability and minimizes myocardial oxygen consumption (MVO2) and consequentially infarct size to prevent the development of subsequent heart failure. In a closed feedback system, the system can include a sensor configured to generate an output used to measure or calculate a left ventricular systolic pressure (LSVP) within the left ventricle of a heart and a controller coupled to a heart pump. The controller can be configured to measure or calculate the LVSP based on the output of the sensor and to control an operation of the heart pump to maximize mechanical unloading of the left ventricle based on the measured or calculated LVSP.
