Final answer:
1) Left; right. The Macintosh blade is inserted in the left side of the mouth and the flange is used to sweep the tongue to the right.
Step-by-step explanation:
The Macintosh blade is inserted in the left side of the mouth, and the flange is used to sweep the tongue to the right.
The Macintosh blade is a type of laryngoscope blade that is commonly used in medical procedures for visualizing the vocal cords and the entrance to the trachea. When inserting the Macintosh blade, it is typically placed in the left side of the mouth to allow for better visualization of the vocal cords and to avoid any damage to the teeth in the process.
Once the blade is inserted, the flange, which is the flat part of the blade at the base, is used to gently sweep the tongue to the right side of the mouth. This helps to position the tongue out of the way and create a clear line of sight for the laryngoscope to visualize the vocal cords.
