Abstract: A device for providing ventilatory assist to a patient is disclosed. The device comprises a manifold having an inspiratory port connectable to an inspiratory supply line, an interface port connectable to an external end of a tube inserted in a patient's trachea and an expiratory port configured to receive an expiratory flow from the tube via the interface port. An inspiratory lumen has a distal end insertable in the endotracheal tube towards its distal end. A cross-section of the inspiratory lumen is smaller than that of the endotracheal tube to allow gas flowing in the endotracheal tube independently from the inspiratory lumen. A valve is configured to direct an inspiratory flow from the inspiratory supply line to the inspiratory lumen, or to the endotracheal tube, or at once to the inspiratory lumen and to the endotracheal tube. A ventilatory assist system and method using the device are also disclosed.

Abstract: The present disclosure relates to a method and a system for validating inspiratory muscle activity of a patient. Left and right electrical activity signals respectively representing activity of a left muscle and of a right muscle synchronized with an inspiratory effort of the patient are acquired from non-invasive sensors. A cardiac activity signal is extracted from the left and right electrical activity signals. A synchrony, a symmetry or a proportionality of the left and right electrical activity signals from which the cardiac activity signal is extracted is verified. A mechanical ventilation system incorporating the system for validating inspiratory muscle activity of the patient is also disclosed.

Abstract: Provided are methods and systems for detecting a maturing arterio-venous fistula comprising a vein. An exemplary method comprises determining a wall thickness of the fistula and a lumen diameter of the fistula vein using a high frequency ultrasound imaging system. A blood pressure of the subject is determined. A circumferential vessel wall stress is determined from the measured blood pressure, the wall thickness of the fistula and a determined radius of the measured diameter of the fistula. The determined circumferential vessel stress is compared to a predetermined threshold stress to determine if the fistula is mature.
