Florida State Paramedic Practice Exam

Where should the curved mac blade be placed during intubation?

1. On top of the epiglottis

2. Between the epiglottis and base of the tongue

3. At the entrance of the trachea

4. Below the uvula

The correct answer is: Between the epiglottis and base of the tongue

The placement of the curved Macintosh blade during intubation is critical for successful visualization of the vocal cords and safe passage of the endotracheal tube. The correct position is between the epiglottis and the base of the tongue. This positioning allows the blade to lift the epiglottis out of the way, thereby uncovering the laryngeal opening, which is essential for clear access to the trachea. When the curved blade is placed in this manner, it utilizes the natural anatomical contours of the airway to elevate the epiglottis without causing trauma or undue pressure on surrounding structures. This facilitates a direct view of the glottic opening, which is important for correct tube placement. Proper placement is crucial; being positioned incorrectly, such as on the epiglottis, might obstruct the view or cause damage, while placement directly at the entrance of the trachea would not allow proper visual access for intubation. Similarly, placing the blade below the uvula doesn't provide the necessary angle for effective visualization of the vocal cords required for successful intubation. Thus, understanding these anatomical relationships and the appropriate placement of the blade enhances both the effectiveness and safety of the intubation process.
