When suctioning an adult's airway with copious secretions, what should you avoid doing?

When suctioning an adult's airway with copious secretions, avoiding contact with the back of the airway is crucial to prevent injury and complications. The back of the airway, specifically the oropharynx and laryngopharynx, contains sensitive structures and can be easily traumatized. Touching this area may cause swelling, spasm, or damage to the tissues, which can complicate the airway management and potentially lead to obstruction.

Maintaining careful technique during suctioning is essential to ensure the patient's safety and optimize airway clearance. Suctioning should be performed with a catheter that fits appropriately, and the duration should be limited to no longer than 15 seconds to minimize hypoxia. The use of a larger suction catheter isn't inherently incorrect, as it may be necessary for clearing copious secretions efficiently, provided it is used with caution and proper technique.
