When should normal saline be used in suctioning procedures?

Normal saline is utilized in suctioning procedures primarily to flush out the airway as needed. This practice helps to moisten secretions, making them easier to suction out. When a patient's airway is obstructed with thick or dried mucus, instilling normal saline can assist in loosening these secretions, thereby improving visibility and facilitating the suctioning process.

Using saline in this manner aims to ensure that the airway remains clear and that the patient can breathe effectively. It is crucial to only use a small amount to prevent complications such as fluid overload or further irritation of the airway.

Other options such as cleaning the suction device or hydrating the patient do not align with the immediate purpose of normal saline during suctioning, and the use of saline to decrease the gag reflex is not a recognized practice in emergency medical care.
