The disposable Ambu TubeChek is a device that reliably confirms if endotracheal tube placement is correct. This tool uses the anatomical differences between the esophagus and trachea to confirm correct ET tube placement. If there is negative pressure, the esophagus has been intubated; if air can be aspirated, correct tracheal intubation has been achieved. There are two versions of the Ambu TubeChek, the syringe or the bulb. This device comes 20 per case.
