Main Functions: 2015 (New Standard): Start with C Chest Compressions → A Open Airway → B Artificial Respiration procedure.

Operation Cycle: First perform 30 effective chest compressions, then 2 effective artificial breaths, i.e., 30:2, five cycles of CPR operation;

Operation Frequency: *New International Standard: At least 100 times/minute;

Simulates standard airway opening.

Simulates manual hand position chest compressions.

Correct compression depth (5-6cm range), incorrect (<5-6cm range).

Mouth-to-mouth artificial respiration (breathing): Tidal volume of breath <500ml-1000ml.

Compression to breath ratio: 30:2.

Operation Mode: Training operation.

Check pupillary response: Simulates comparison of one dilated pupil and one constricted pupil for recognition.
