Functional Features: Executive Standard: Aligned with the 2020 American Heart Association (AHA) guidelines for international CPR and Cardiovascular first aid (ECC). 2020 (New Standard): Follows the updated CPR process: initial C external chest compression, followed by A open airway, and then B artificial respiration. Operation Cycle: Involves 30 effective external chest compressions followed by 2 rounds of effective manual air blowing, constituting a 30:2 CPR operation cycle. Operating Frequency: Adheres to the latest international standard of at least 100 compressions per minute. Simulated Standard Airway Opening: Ensures realistic simulation of airway opening procedures. Simulated Manual Chest Compressions: Allows for realistic practice of manual chest compressions. Correct and Incorrect Pressing Strength: Provides feedback on the accuracy of pressing strength, differentiating between the correct (5-6cm area) and incorrect (< 5-6cm) applications. Mouth-to-Mouth Breathing (Blowing): Simulates breathing with a tidal volume between < 500ml and 1000ml. Compression to Artificial Respiration Ratio: Maintains the standard ratio of 30 compressions to 2 artificial respirations. Operation Mode: Designed for training purposes. Pupil Response Check: Simulates a comparison between one dilated pupi
