Hyperoxygenation: Avoiding Hypoxia During Endotracheal Suctioning

How can a nurse avoid hypoxia during endotracheal suctioning?

A) Inserting a fenestrated catheter with a whistle tip without suction

B) Completing suction pass in 30 seconds with pressure of 150 mm Hg

C) Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass

D) Minimizing suction pass to 60 seconds while slowly rotating the lubricated catheter

Correct Answer: C) Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass

To avoid hypoxia during endotracheal suctioning, the nurse should hyperoxygenate the patient with 100% O2 for 1 to 2 minutes before and after each suction pass.

When caring for a client on mechanical ventilation, it is crucial to prioritize their respiratory needs to prevent complications such as hypoxia during procedures like endotracheal suctioning. By hyperoxygenating the patient with 100% O2 for 1 to 2 minutes before and after each suction pass, the nurse can ensure that the patient's oxygen levels remain stable throughout the procedure.

This practice of pre-oxygenation and post-oxygenation before suctioning is essential to minimize the risk of hypoxia, which can occur if the oxygen supply is interrupted. Rapid or high-pressure suction, as well as prolonged suctioning time, can lead to a significant drop in oxygen levels for the patient and should be avoided.

During endotracheal suctioning, the nurse should aim for quick and efficient suction passes, using a lubricated catheter and taking great care to minimize any discomfort or further risk to the patient. By following these guidelines and prioritizing the patient's respiratory well-being, nurses can ensure safe and effective endotracheal suctioning procedures.
