Which of the following is not a correct instrument to confirm endotracheal tube placement during intubation?

Explanation:
Confirming endotracheal tube placement relies on detecting CO2 in the airway. Real-time waveform capnography shows a CO2 waveform that confirms the tube is in the trachea, and a colorimetric end-tidal CO2 detector changes color when CO2 is present, providing immediate confirmation. A laryngoscope is used during intubation to visualize the cords and guide placement, helping ensure the tube goes into the trachea. Pulse oximetry, while essential for monitoring oxygenation, does not tell you where the tube is; a patient can be ventilated with an incorrect tube location for a time, so it doesn’t reliably confirm placement.
