What would you do if your teammate suddenly fell to the ground on the football field without warning?

Call 120 to determine what kind of syncope it is. If you witness the process of fainting, remember to see where to land first. If nothing else, breathing and heartbeat are the most important things, right? Breathing can see the ups and downs of his chest, and you can also check his snorting and snorting. Remember to compare with yourself. If you have a heartbeat, you can explore the main arteries of your neck and wrist. If all the above are normal, see how he will react when he is called, patted and poked. The reaction here is not only whether I should answer your words, but also whether there are some slight reactions, such as finger twitching, eye twitching ... and then you can start doing things like pinching people. Needless to say, everyone knows what to do. If the above is not normal, call 120 quickly, and then use the daily first aid knowledge of cardiopulmonary resuscitation.
