What indicates a failed intubation attempt?

A failed intubation attempt is indicated by the inability to visualize the vocal cords after multiple attempts. Visualization of the vocal cords is a critical step in confirming the correct position for intubation. If a clinician is unable to see the vocal cords despite several tries, it suggests that the procedure is unsuccessful. This condition may arise due to various factors, such as anatomical challenges or difficult airway situations, necessitating an alternative approach or airway management strategy.

In contrast, successful visualization of the vocal cords indicates a successful intubation attempt. The presence of patient cooperation during insertion does not contribute to the evaluation of success or failure in visualizing the airway; rather, it can be advantageous for the procedure. Immediate confirmation of tube placement is a separate step that follows visualization and does not inherently indicate whether or not the intubation attempt was initially successful.
