For bag-valve-mask (BVM) ventilation, the goal is to give just enough air to produce visible chest rise, not to fully squeeze the bag.

Adult BVM volume

  • Typical recommended tidal volume for most adults is about 500–600 mL per breath (roughly 6–7 mL/kg ideal body weight).
  • This should be delivered over about 1 second per breath, watching for gentle chest rise (not forceful expansion).

Pediatric and infant volumes

  • Children generally need smaller volumes based on weight , often around 4–8 mL/kg depending on age and guideline set.
  • Infants commonly require about 4–6 mL/kg , and many training resources emphasize using an infant-sized BVM and giving only enough to see a slight chest rise.

Practical bedside rule

  • Use a gentle, controlled squeeze of the bag over 1 second, stopping as soon as you see visible chest rise.
  • Avoid fully compressing the bag, since that can easily exceed 1,000 mL and increase risk of gastric insufflation and barotrauma.

Safety note

  • Always follow your local protocols, current AHA/ILS/ALS guidelines, and device-specific instructions, and use monitoring (SpO₂, EtCO₂, chest rise) to titrate volume whenever available.
