Mechanical ventilation, assisted ventilation or intermittent mandatory ventilation (IMV), is the medical term for artificial ventilation where mechanical means are used to assist or replace spontaneous breathing. An emergency procedure in which a catheter is placed percutaneously through the cricothyroid membrane and attached to a high-pressure, high-flow jet ventilator. Periodic assisted ventilation with positive pressure initiated by the patient and coordinated with spontaneous patient breaths. When it is hot humid and muggy outside she find it hard to breath. A mechanical method of assisting pulmonary ventilation, using a device that inflates the lungs under positive pressure. Dual control is asserted when pressure limited breaths are delivered and the pressure changes from breath to breath to meet a desired delivered tidal volume.
