Final answer:
Airway adjuncts are used to maintain a clear and open airway. BVM ventilation can be initiated after inserting an airway adjunct.
Step-by-step explanation:
Airway adjuncts are devices used to maintain a clear and open airway during resuscitation. They can be inserted when a person is unconscious or unable to maintain their own airway. Examples of airway adjuncts include nasopharyngeal airways and oropharyngeal airways.
Assisting ventilations with a Bag-Valve-Mask (BVM) is done when a person is not breathing adequately or not breathing at all. The BVM is a handheld device used to provide positive pressure ventilation by manually squeezing the bag to deliver oxygen to the patient. BVM ventilation may be initiated after inserting an airway adjunct to improve the effectiveness of the ventilation.
