A Breath Resuscitation Bag (manual resuscitator, bag-valve-mask) is a Class II medical device used to deliver positive-pressure ventilation to patients in respiratory arrest, cardiac arrest, or respiratory failure. Available in adult (1,500-2,000 mL), pediatric (450-750 mL), and infant/neonatal (200-350 mL) sizes with self-inflating silicone or PVC bags, one-way non-rebreathing valves, transparent cushioned masks, and oxygen reservoirs for high FiO2 delivery (90-100% with reservoir). Oxygen inlet allows connection to flow meter (10-15 L/min recommended). Pediatric/neonatal models include pressure-limiting valves (35-45 cmH2O) to prevent barotrauma. Essential for CPR (AHA guidelines: adult 10-12 breaths/min, child 12-20, infant 20-30), preoxygenation before intubation, transport ventilation, and recovery from anesthesia. Critical safety considerations include avoiding excessive ventilation pressure (prevents gastric insufflation), maintaining proper mask seal, monitoring chest rise, and having backup equipment readily available. Indispensable emergency airway equipment in hospitals, ambulances, crash carts, and emergency response kits worldwide.
