Verification and accuracy of ET tube placement is imperative when intubating a patient. The disposable Ambu^® TubeChek is a bulb-style device that rapidly and reliably confirms if endotracheal tube placement is correct depending on the pressure. The bulb illuminates in the dark, making it a convenient and ideal choice for pop-up situations in any environment. The simple 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. If the tube is in the soft, unsupported esophague, the walls will collapse around the end of the endotracheal tube, creating negative pressure if you attempt to aspirate air. If the tube is in the rigid trachea, air can easily be aspirated.
