Which ventilation method typically uses two rescuers to deliver breaths?

• A. Mouth-to-mouth
• B. BVM - 2 person
• C. Oxygen powered device
• D. BVM - 1 person

Answer: (B)

Delivering breaths with a bag-valve-mask is most effective when two rescuers work together: one person maintains a secure mask seal and keeps the airway open, while the other squeezes the bag to provide the breaths. This two-person coordination produces better chest rise, minimizes air leaks around the mask, and reduces fatigue for the rescuer delivering breaths, especially during longer resuscitation efforts. When two rescuers are present, this BVM technique is the standard approach, offering consistent ventilation and efficient oxygen delivery. Other methods involve a single rescuer or devices not specifically arranged for two-person ventilation, so they don’t reflect the typical two-rescuer setup. Deliver breaths at a steady rate, about one every 5–6 seconds for adults.
