What combination of rescuers is required for effective use of a bag-valve-mask resuscitator?

• A. One rescuer using both ventilation and airway management
• B. Two rescuers: one to manage the airway, one to deliver ventilations
• C. Three rescuers: two ventilating, one airway
• D. A single rescuer can do both

Answer: (B)

Bag-valve-mask ventilation works best when two rescuers share the tasks: one keeps the airway open and maintains a good mask seal, while the other squeezes the bag to deliver breaths. The person managing the airway uses a jaw-thrust or head-tilt to keep the airway open and ensures the mask fits snugly to minimize leaks. The other rescuer delivers breaths with the bag at the right rate and volume, so each breath produces visible chest rise. Having two rescuers allows continuous, effective ventilation without compromising the seal or the depth of each breath. If one person tried to do both tasks, maintaining a reliable mask seal and delivering consistent breaths at the correct rate would be much harder, leading to poor ventilation. In practice, this two-rescuer setup is the standard for effective BVM use.
