What might be required after mouth-to-mouth or bag-mask ventilation?

After administering mouth-to-mouth or bag-mask ventilation, the correct measure is to use a gastric tube to decompress the stomach. This is important because during the process of ventilation, air may inadvertently be delivered to the stomach rather than the lungs, leading to gastric distension. When the stomach becomes distended with air, it can impede diaphragmatic movement and make subsequent effective ventilation more difficult. Using a gastric tube helps relieve this pressure by decompressing the stomach, facilitating easier and more effective breathing.

In contrast, immediate surgery is typically not indicated in such situations unless there is a specific life-threatening condition identified that requires surgical intervention. A second set of electrodes refers to defibrillation in cases of cardiac arrest and is not directly related to the need for airway management post-ventilation. Returning to a normal diet is not applicable in this context, as dietary considerations pertain to recovery phases after medical interventions, not acute management following ventilation.
