What type of breathing technique is used in assisted ventilation?

• A. Nasal cannula delivery
• B. Simple face mask
• C. Bag-valve-mask (BVM) ventilation
• D. Endotracheal intubation

Answer: (C)

Assisted ventilation is a technique used to provide air to patients who are unable to breathe effectively on their own. In this context, bag-valve-mask (BVM) ventilation is the primary method employed. BVM ventilation involves using a self-expanding bag, a unidirectional valve, and a facial mask to deliver positive pressure ventilation to the patient. The clinician squeezes the bag, which forces air (or oxygen) into the lungs of the patient. This technique is critical in emergency situations where a patient may be apneic (not breathing) or breathing inadequately. The effectiveness of this method is due to its ability to provide sufficient volumes of air quickly and effectively, ensuring that the patient's oxygenation and ventilation needs are met. Other techniques mentioned, such as nasal cannula delivery and simple face masks, are generally used for supplemental oxygen rather than assisted ventilation. They do not provide the positive pressure necessary for assisting or controlling ventilation in patients who are unable to breathe adequately. Endotracheal intubation, while it provides a secure airway to assist ventilation, is a more invasive procedure and is performed in situations where advanced airway management is required. In contrast, BVM ventilation can be applied in many emergency scenarios with relative ease and immed
