Brief Summary
One-lung ventilation can be provided by an endobronchial blocker. The Uniblocker® (Fuji Systems Corporation, Tokyo, Japan) was relatively recently introduced into clinical practice. We will try to devise a blind method to locate the Uniblocker® without the aid of fiberoptic bronchoscopy.
