    Abstract: A device for providing ventilatory assist to a patient is disclosed. The device comprises a manifold having an inspiratory port to receive an inspiratory flow from an inspiratory supply line, an interface port connectable to an external end of an endotracheal tube inserted in a patient's trachea and an expiratory port configured to receive an expiratory flow from the endotracheal tube via the interface port. An inspiratory lumen has a distal end insertable in the endotracheal tube. A cross-section of the inspiratory lumen is smaller than that of the endotracheal tube to allow gas flowing in the endotracheal tube. The inspiratory flow is directed 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: The present disclosure relates to a method and a mechanical ventilation system for adjusting a level of ventilatory assist to a patient. A neuro-mechanical efficiency of the patient is determined. A control value is received at the mechanical ventilation system. The level of ventilatory assist to the patient is determined on the basis of the neuro-mechanical efficiency and of the control value. The mechanical ventilation system may be adjusted automatically based on the determined level of ventilatory assist to the patient. Alternatively, the determined level of ventilatory assist to the patient may be displayed for the benefit of an operator and a manual command may be received for adjusting the mechanical ventilation system.
