What is the two-person BVM technique?

• A. The second rescuer squeezes the bag to deliver breaths.
• B. The person with the mask squeezes the bag.
• C. One rescuer maintains a tight seal on the mask while the second rescuer squeezes the bag to deliver breaths.
• D. Use mouth-to-mouth ventilation only.

Answer: (C)

Two-person bag-valve-mask ventilation relies on teamwork: one rescuer keeps a tight mask seal and maintains the airway position, while the other rescues squeezes the bag to deliver breaths. This setup improves ventilation by reducing leaks and delivering consistent tidal volumes, with the mask seal person focused on airway protection and seal, and the bag-squeezer providing controlled, adequate breaths and watching for chest rise.

If the same person tried to do both tasks, the seal can become compromised and ventilation becomes ineffective. Mouth-to-mouth ventilation is a different technique that uses no bag-valve-mask setup, so it’s not describing the two-person method.
