bag-mask ventilation

Bag-mask ventilation is a medical technique used to help someone breathe when they are unable to do so on their own. It involves using a bag that contains air (or oxygen) and a mask that fits over the person's nose and mouth. When the bag is squeezed, it pushes air into the person's lungs, helping to provide oxygen and remove carbon dioxide. This method is crucial in emergencies, such as during cardiac arrest or severe respiratory distress, allowing medical responders to maintain airflow until more advanced medical care can be provided.
