To raise awareness on basic life support in times of disasters and calamities, the local government of Muntinlupa and Philippine Heart Association launched the Simultaneous Mass Demo of Hands Only CPR on Monday. Around 700 volunteers from local communities and the private sector performed a hands-only cardiopulmonary resuscitation at the Muntinlupa Sports Complex in Barangay Tunasan. The demonstration is part of the month-long celebration of National Disaster Consciousness Month in Muntinlupa City.
