What is the maximum suction time for a patient with a tracheostomy?

5 seconds
10 seconds
30 seconds
1 minute

Explanation

Answer: B - The nurse would want to limit suctioning to 10 seconds through a tracheostomy. Hypoxemia can be caused by prolonged suctioning and will stimulate the pacemaker cells in the heart. This could lead to a vasovagal response, which will cause bradycardia. The patient will need to be preoxygenated prior to suctioning.
