When a endotracheal tube is inserted how does the emt know it is properly placed?

An EMT can confirm proper placement of an endotracheal tube by checking for bilateral breath sounds using a stethoscope, observing chest rise and fall, and ensuring the absence of gastric sounds. Additionally, they can utilize capnography to measure exhaled carbon dioxide, which should indicate normal levels if the tube is correctly positioned in the trachea. Finally, visual confirmation of tube placement can be achieved through direct observation of the tube passing through the vocal cords.
