At Kuala Lumpur International Airport (KLIA), I saw this strange looking red hearts signage and upon closer look, it is an emergency heart defibrillator. I do hope that there are enough medical officers among the passengers that can fully utilized the gadget. For non medical personnel such as me, I can only look at the gadget and not sure on how to use it.
Picture below shows a close up of the defibrillator. I is confirmed that the heartstart can only be used by qualified personnel among the airport employees.
