1) A new device called provides real-time feedback to improve manual ventilation techniques during CPR training which can help save more lives. 2) Proper airway management and ventilation are crucial but difficult parts of performing CPR. Issues like leakage, gastric insufflation, and hyperventilation commonly occur without feedback and training. 3) The device allows trainees to practice airway management skills and receive feedback on ventilation metrics to help ensure adequate volumes while avoiding common issues like hyperventilation that can reduce survival rates.
