How deep can a suction tube be inserted?

The correct consideration for the depth of suction tube insertion is that it should not exceed the depth that you can see. This approach helps to avoid causing trauma to the airway and surrounding structures. Suctioning too deeply can lead to complications such as injuring the trachea, esophagus, or other vital structures, and it may also increase the risk of hypoxia if it interferes with oxygenation during the procedure.

When suctioning, it’s important to visualize the depth to maintain safety and control. The technique emphasizes utilizing your sight as a guiding measure to prevent over-insertion, rather than arbitrary depths or maximum limits. Therefore, the focus on visual guidance ensures a balance between effective suctioning and patient safety.
