Rapid feedback to confirm the correct placement of an endotracheal tube immediately after in-tubation is achieved by which of the following?
a. Capnography c. CAT Scan
b. Chest radiography d. Fiberoptic bron-choscopy
ANS: A
The most sensitive and rapid way to confirm correct placement is to detect expired carbon diox-ide by means of a capnograph or a color-change capnometric device. A chest radiograph is used to determine proper position with respect to the carina. Chest auscultation is subjective, and re-ferred sounds from the stomach might be confused with breath sounds. Fiberoptic bronchoscopy is another way to confirm placement, but this procedure may take time for preparation.
