Which statement indicates proper suctioning technique by an OEC technician?

The selected answer is correct because it acknowledges the need for an adaptive technique in a scenario where there is active bleeding in the patient's mouth. Using gravity to aid suctioning can be beneficial in effectively clearing the area while maintaining the patient's safety. In such a situation, suctioning alone may not suffice, as direct suctioning could dislodge clots or actively bleeding tissue.

To ensure the patient’s airway is clear, it’s ideal to use gravity to help manage the blood or fluid while simultaneously applying suction, which also helps to create a safer environment for airway management. This technique is particularly useful in emergency situations where rapid clearing of the airway is critical.

The other statements do not convey appropriate suctioning techniques. For instance, suctioning should not be limited to unconscious patients only, as those who are conscious may also require suctioning if their airway is compromised. The recommendation that suctioning should take no longer than 30 seconds is a good practice to minimize the risk of hypoxia but does not encompass the broader context of managing bleeding or fluid obstruction. Lastly, continuously vacuuming the mouth is discouraged because it can lead to potential further complications, such as trauma to the mucosa or worsening bleeding, rather than effective management of the airway.
