Why is a two-handed mask grip recommended for BVM ventilation?

• A. Increases risk of leaks
• B. Creates a better seal and reduces air leaks
• C. Is faster only in children
• D. Requires less training

Answer: (B)

A tight, reliable seal around the mask is essential for effective bag-valve-mask ventilation. Using a two-handed mask grip lets you press the mask firmly with both hands while maintaining a proper airway position (jaw thrust and a steady head/neck alignment). This creates a much more airtight seal around the mask edges, so far less air leaks out when you squeeze the bag. With fewer leaks, the delivered breaths reach the lungs with the intended tidal volume, improving oxygenation and ventilation and reducing the risk of gastric insufflation. This approach is especially important in difficult airways or challenging faces ( facial hair, trauma, dentures) and is generally preferred for reliable ventilation, whereas a one-handed grip is more prone to slipping and leaks.
