What area should be covered by a pocket mask or BVM during ventilation?

• A. Mouth and nose
• B. Only the chin
• C. Only the mouth
• D. Mouth and ears

Answer: (A)

A pocket mask or bag-valve-mask (BVM) is designed to create a seal over the airway to ensure that air is effectively delivered to the lungs during ventilation. Covering both the mouth and nose is crucial for several reasons. When using a pocket mask, the mask fits over the patient's mouth and nose, allowing for both oral and nasal ventilation. This configuration helps prevent air from escaping and ensures that the patient's airways remain clear while facilitating a proper flow of oxygen. Additionally, covering both areas helps to minimize the risk of aspiration and keeps the secretion from entering the lungs. For BVM use, the same principle applies; to achieve effective positive pressure ventilation, the mask must seal over both the mouth and nose. Properly positioned, the BVM can help to inflating the lungs more efficiently, leading to better overall ventilation outcomes. Considering all these factors, the correct response emphasizes the comprehensive coverage necessary for effective ventilation.
