Which statement about the BVM method is true?

The statement that the two-person technique is optimal for better seal is accurate because utilizing two providers allows for improved effectiveness when using the Bag-Valve-Mask (BVM) method. One provider manages the mask application, ensuring a tight seal over the patient's face, while the other squeezes the bag to deliver breaths. This collaboration enhances the ability to maintain sufficient ventilation, especially in emergency situations where correct delivery of oxygen is critical.

By using a two-person technique, the risks of air leaks are minimized, allowing for more effective ventilation and reducing the potential for insufficient oxygen delivery. In contrast, a one-person technique can be effective in emergencies, but it may not ensure the same quality of seal and ventilation achieved by two trained providers working in tandem.

Other statements are not accurate with respect to BVM usage; it can certainly be applied to both adults and children, and it can be utilized in conjunction with supplemental oxygen to enhance patient outcomes.
