The recommended duration of suction application when withdrawing a catheter during suctioning is typically 10 seconds. This guideline is essential because excessive suction duration can lead to complications such as hypoxia, mucosal damage, and discomfort for the patient. The 10-second limit allows for adequate clearance of secretions while minimizing the risk of these adverse events.

In practice, it is crucial to ensure that suctioning is performed effectively and safely, which includes not only the duration of suctioning but also the factors like the strength of suction and the frequency of suctioning based on the patient's needs. This established time frame aims to balance efficacy in clearing airways while protecting patient safety, aligning with best practices in respiratory care.
