The present disclosure provides a unique solution for assisting in the ventilation of lungs of subject that is performed by artificial mechanical ventilator. The solution of the present invention improves the efficiency of the ventilation effect by applying desired pressure profile on portions of the upper body part of the subject in synchronization with the mechanical ventilator operation, thereby creating a desired pressure profile or gradient in the lungs airways to ensure that air pumped into the lungs by the mechanical ventilator spreads more homogeneously in the lungs than without the intervention of the system of the present invention. The application of pressure is determined after analyzing data from sensors of the system that are placed on a plurality of portions on the upper body part of the subject and data received from the mechanical ventilator. These sensors sense data indicative of the ventilation profile within the lungs, i.e. pressure profile along different portions of the lung. The system provides extra-thoracic pressure on the rib cage according to pre-defined and adaptive algorithms based on the physiological status, the respiratory mechanics, and the inhomogeneous nature of lung injury. By applying pressure to the hyperventilated areas and reducing the transpulmonary pressure gradient, the system prevents hyperinflation trauma to the open areas and atelecto-trauma to the closed areas. The system is synchronized with the mechanical ventilator and adapt to changes in the patient's respiratory mechanics.
