Which of the following is/are accurate about nasotracheal suctioning? Select all that apply.

A) Apply suction for no longer than 15 sec during a single pass.
B) Apply suction while inserting and removing the catheter.
C) Reapply oxygen between suctioning passes for ventilator patients.
D) Gently rotate the suction catheter as you remove it.

Limiting suctioning to 15 seconds or less and reapplying oxygen between suctioning passes prevent hypoxia.Suction should be applied only while withdrawing the catheter,using a continuous rotating motion to prevent trauma to the airway.Endotracheal suctioning is used when the patient is being mechanically ventilated,and most ventilator patients have in-line suctioning,so there is no need to reapply oxygen.
