The contents of ambulance training are mainly on-site, primary and easy-to-master ambulance knowledge and skills. It mainly includes four basic skills of hemostasis, dressing, fixation and handling, as well as on-site cardiopulmonary resuscitation skills, disaster protection and emergency rescue. When any accident happens, it takes a long time to send critically ill patients to the hospital or the medical emergency system arrives at the scene. During this period, once the patient has symptoms such as bleeding, dyspnea or even cardiac arrest, which is called "prime time" in medicine for 4-6 minutes, the best first aid time will be delayed, resulting in lifelong disability or even more serious consequences. If you are the first witness, and you happen to learn the skills of on-site rescue (also known as "primary health care"), you can save a dying fresh life between your hands, and your merits are boundless. Theoretically, all injured people in accidents need to be rescued on the spot before they arrive at the hospital, including drowning, electric shock, burns, falls, food poisoning and acute attacks. However, judging from the situation of emergency rooms in hospitals around the country, there are not many injured people who are lucky enough to get on-site rescue. /news_view.asp？ newsid= 168
