Which technique is correct when suctioning a tracheostomy?
Correct answer: B. Advance without suction, then apply suction while withdrawing
- A. Apply suction while inserting the catheter for 30 seconds
- B. Advance without suction, then apply suction while withdrawing
- C. Use continuous suction while advancing and withdrawing
- D. Instill sterile water routinely before every suction pass
Explanation
The catheter is advanced without suction and suction is applied intermittently while the catheter is withdrawn and rotated. Each pass should be brief, usually no longer than 10 to 15 seconds, to reduce hypoxia and mucosal trauma.
