Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. The system includes an applicator device configured to provide ACD CPR treatment to a patient's chest according to a plurality of phases at least one sensor configured to be coupled to the patient's chest and to measure at least one parameter related to the ACD CPR treatment and information for determining whether at least one transition point of the ACD CPR treatment has been reached; and one or more processors configured to provide a feedback signal based on a parameter for administering ACD CPR treatment to the patient's chest according to a desired treatment protocol.

A mechanical ventilation system comprises a plurality of ventilation therapy sub-systems. Each of the ventilation therapy sub-systems is adapted to assist a respiratory function of the patient. The system also comprises a detector of the respiratory drive of the patient, an operator interface receiving one or more control parameters, and a main controller. The main controller assigns a therapeutic contribution to each of the ventilation therapy sub-systems based on the respiratory drive of the patient and on the control parameters. The controller modulates the respiratory drive of a patient by controlling each of the plurality of the ventilation therapy sub-systems according to its assigned therapeutic contribution. Distinct ventilation therapy sub-systems may apply negative pressure on the abdomen of the patient, deliver a non-pressurizing inspiratory flow to the patient, or induce a positive pressure in the airways of the patient.

Ventilator, consisting of at least: • a breathing gas pump (1), • a connection (2) for a ventilation device, • a connection for external and / or integrated measuring devices (3) for measuring respiratory and / or device measurements, • Storage devices (4) for measurement data, • a data processing device (5) for calculating and / or transmitting control parameters which at least temporarily influence at least one device function; characterized in that the ventilator is designed such that during its operation: • temporarily perform measurements with the measuring instruments (3), the measurement data of which are stored in the storage instruments (4), without the data processing device (5) calculating control parameters from this and without the measurement data stored during this time being able to influence the device control; • temporary measurement data from the measuring means (3) and / or storage data from the storage means (4) are provided by the data processing device (5) as control parameters with or without further calculations, wherein the data processing device (5) performs an analysis of the flow history, and influence at least one device function, wherein a separate control device (6) or a control device integrated into the data processing device (5) is designed to determine whether and when the data processing device (5) provides control parameters and whether and when such control parameters influence at least one device function.

The invention discloses a respiratory support system and method with in-vitro negative pressure cooperating with electrical stimulation. The method comprises the steps that a signal detection module collects body surface respiratory muscle electromyography, thoracic posture, thoracico-abdominal deformation and respiratory airflow signals of a patient in real time; the negative pressure ventilation module generates negative pressure outside the thorax of the patient through a thoracic nail, a vacuum pump, a pressure reducing valve and a two-position three-way valve to reduce the pressure of a pleural cavity and pulmonary alveoli; the constant-current electrical stimulation module applies constant-current electrical stimulation to the diaphragm to enhance the contractility of the diaphragm; the control module receives the respiratory physiological signal, judges the respiratory intention of a patient through a built-in respiratory intention recognition algorithm, and controls the negative pressure ventilation and electrical stimulation module to realize triggering of an inspiration phase and an expiration phase and man-machine synchronization; through the synergistic effect of negative pressure ventilation and electrical stimulation, the respiratory support effect and man-machine synchronism are improved, and the device is suitable for adjuvant therapy of respiratory dysfunction patients.

The present disclosure relates to an exoskeleton robot for expectoration assistance and a control method. In the exoskeleton robot, a respiratory sensor acquires a respiratory signal of a user to be assisted; a positive pressure module covers an upper abdomen of the user to be assisted; a negative pressure module is arranged on an outer wall of a thoracic cavity of the user to be assisted and wraps the whole thoracic cavity, and a negative pressure cavity is formed between a housing of the negative pressure module and the outer wall of the thoracic cavity; in an inhalation state, the rigidity of the housing of the negative pressure module increases; in an exhalation state, the rigidity of the housing of the negative pressure module decreases; the control module is respectively connected with the respiratory sensor, the positive pressure module, and the negative pressure module.

The present disclosure provides a wearable breath tracking device, and a system and method for operation of the device. The system includes a wearable breath tracking device adapted to be removably fitted on a nose of a user. The device includes a first set of sensors adapted to be positioned inside one or both nostrils of the user and configured to generate signals indicative of an air pressure. The system further includes a controller configured to receive, from the first set of sensors, signals indicative of the air pressure in one or both nostrils of the user; determine a peak air pressure difference defined as a deviation in values of air pressure from a mean value of air pressure during a predefined duration of time; and evaluate a breathing score based on peak air pressure difference. The breathing score is indicative of breathing fitness and health of the user.

An exemplary method and pneumatic vest system (also referred to herein as a V / Q vest) are disclosed for improving oxygenation that can reproduce the effects of proning treatment. The exemplary pneumatic vest can be used synergistically with proning, as a replacement therapy for proning treatment, and / or to monitor or assess whether patients would respond well to a proning treatment. The exemplary pneumatic vest can be integrated with sensors and intubation equipment. The compression vest system can integrate a mechanical ventilator with a pneumatic compression vest to improve oxygenation, provide potential alternative or bridge to proning patients, and / or reduce mechanical ventilatory morbidity.
