Inhomogeneous ventilation was more likely to happen in patients after general anesthesia. Inhomogeneous ventilation may associate with ventilator-induced lung injury. A large number of post-neurosurgical patients was delayed extubation and received mechanical ventilation, so that, inhomogeneous ventilation was more likely to happen in the population. Electrical impedance tomography (EIT) is an noninvasive, radiation-free, high temporal resolution, relatively cheap technique in monitoring ventilation distribution bedside. The investigators aimed to investigate the incidence of inhomogeneous ventilation and factors associated with inhomogeneous ventilation in post-neurosurgical patients under mechanical ventilation.

Incidence of inhomogeneous ventilation
In supine position, global image of EIT was divided into upper and lower part, each part accounting for 50%, which was named as non-dependent region and dependent region respectively. Inhomogeneous ventilation was defined as the ratio between tidal impedance variation of dependent region(VTdep) and global tidal impedance variation (VT) is less than 45% during stable Spontaneous breath, which was defined as variation of tidal volume less than 10% in continuous 6 breathes.
