A device (10) processes and visualizes EIT data (3) of at least one region of the lungs to determine and visualize ventilation delays in the lungs of a living being. The EIT data (3) are obtained from an electrical impedance tomography apparatus (30). The device makes it possible to visualize regional ventilation delays of the lungs or of regions of the lungs in which the delay exceeds a predefined duration (76) in a joint image (900).

Devices, systems and methods of neurostimulation for treating obstructive sleep apnea. The system is adapted to send an electrical signal from an implanted neurostimulator through a stimulation lead to a patient's nerve at an appropriate phase of the respiratory cycle based on input from a respiration sensing lead. External components are adapted for wireless communication with the neurostimulator. The neurostimulator is adapted to deliver therapeutic stimulation based on inputs.

A wearable cardioverter defibrillator (WCD) system comprises a plurality of patient parameter electrodes and a plurality of defibrillator electrodes to contact a patient's skin when the WCD is delivering therapy to the patient, a processor to receive one or more patient parameters from the one or more patient parameter electrodes, an energy storage device to store a charge to provide electrical therapy to the patient via the plurality of defibrillator electrodes, and a non-invasive blood pressure (NIBP) monitor to obtain a blood pressure measurement of the patient and to provide the blood pressure measurement to the processor. The processor is to determine whether to provide electrical therapy to the patient based on the one or more patient parameters during an episode, and to obtain the blood pressure measurement from the NIBP monitor during the episode.

The method comprises: generating a three-dimensional ventilation image by means of a signal extraction algorithm and an image reconstruction algorithm and according to an electrical impedance signal obtained by performing electrical impedance measurement on a target region to be measured, wherein performing electrical impedance measurement on said target region is implemented by using an electrode array that is three-dimensionally distributed on the periphery of said target region.

Systems and methods of evaluating a patient comprise the steps of obtaining temporal data of the patient after an event, monitoring a plurality of patient parameters, compiling patient data based on the temporal data and patient parameters, determining a state or change in state of the patient based on the compiled patient data, and alerting medical staff of the state or change in state.

The present disclosure relates to a method (MO) for providing respiratory timing parameters from respiratory monitoring measurements of a subject, the method comprising the steps of: providing (M1) a respiratory effort signal (E) and a respiratory flow signal (F) of a subject; determining (M2a) an ensemble of peaks (pE) in the respiratory effort signal (E) and determining (M2b) an ensemble of valleys (vE) in the respiratory effort signal (E); and identifying (M3) times associated with the valleys (vE) as preliminary inspiratory onset times (tio); refining (M4) preliminary inspiratory onset times (tio) within respective peak-to-peak time intervals (Tpp) of the respiratory effort signal (E) by: determining (M41) first derivative (F1d) of the respiratory flow signal (F) in a respective peak-to-peak interval (Tpp); determining (M42) local peaks (pF1d) and valleys (vF1d) in the respiratory flow signal first derivative (F1d); determining (M43) a time midpoint (tmid) between the time of a local valley (vF1d) in the respiratory flow signal first derivative (F1d) closest in time to the later endpoint in the respective peak-to-peak time interval (Tpp) and the time of a local peak (pF1d) in the respiratory flow signal derivative (F1d) in the respective peak-to-peak time interval (Tpp); evaluating (M44) whether the respiratory effort signal (E) at the determined time midpoint (tmid) satisfies a predetermined inspiratory onset time condition, and if satisfied, selecting (M45) the determined time midpoint (tmid) as an inspiratory onset time (tio) instead of the preliminary inspiratory onset time (tio) for that peak-to-peak interval (Tpp), whereas if the condition is not satisfied, keep the preliminary inspiratory onset time as the inspiratory onset time for that peak-to-peak interval.
