<unk>  <unk>  is a mode of mechanical ventilation.<unk>  delivers<unk> ance in proportion to and in synchrony with the patient's respiratory efforts, as reflected by an electrical signal. This signal represents the electrical activity of the diaphragm, the body's principal breathing muscle. The act of taking a breath is controlled by the respiratory center of the brain, which decides the characteristics of each breath, timing and size. The respiratory center sends a signal along the phrenic nerve, excites the diaphragm muscle cells, leading to muscle contraction and descent of the diaphragm dome. As a result, the pressure in the airway drops, causing an inflow of air into the lungs. With<unk> , the electrical activity of the diaphragm (Edi) is captured, fed to the<unk> and used to<unk>  the patient's breathing in synchrony with and in proportion to the patients own efforts, regardless of patient category or size. As the work of the<unk> and the diaphragm is controlled by the same signal, coupling between the diaphragm and the SERVO-i<unk> is synchronized simultaneously.
