“bougie” (pronounced the same) can also refer to a slender blue plastic rod ever so slightly crooked at the end, used to aid in placement of an endotracheal tube. you use the crooked tip to feel the ribbing of the trachea, then insert the ET tube around the bougie. not ideal to use without also using a laryngoscope but one of several methods of confirmation, since ventilation into the wrong organ can have disastrous consequences
