1. Intelligence: touch-tone operation, which supports the free switch of proportioning mode between various breathing and instruction; 30:2/15:2 / Continuous continuous pressure/continuous ventilation.
2. Safety: cantilever open classic vertical press, unique startup default safety state.
3. Accuracy: pressing depth ≤2mm, pressing frequency 0 error. Press the position constant, not displacement.
4. Quick: Quick plug air source access, quick start design within 2 seconds, 360 degree arbitrary rotation, arbitrary insertion on both sides of the resuscitation plate, convenient to cooperate with defibrillation and other rescue measures.
