What is the primary benefit of a bag-valve mask when used by two rescuers?

• A. It allows for easier seal
• B. It provides positive pressure ventilation
• C. It requires less coordination
• D. It can be used on infants

Answer: (B)

The primary benefit of a bag-valve mask when used by two rescuers is that it provides positive pressure ventilation. This method is especially effective in delivering oxygen to a patient who is not breathing adequately or at all. When two rescuers work together, one can maintain a proper seal around the patient's mouth and nose while the other squeezes the bag to deliver air or oxygen into the lungs. With two rescuers, the coordination allows for a more controlled and effective delivery of breaths, minimizing the risk of air escaping and ensuring that each breath is effectively administered. This contrasts with using a bag-valve mask alone, where it can be more challenging to maintain the necessary seal while also operating the bag effectively. While a better seal is a potential advantage of two rescuers, the paramount benefit is the effective delivery of positive pressure ventilation to assist the patient’s respiratory effort. The requirement for coordination does not diminish the function of providing breaths; rather, it enhances the overall effectiveness of the ventilation.
