Three, briefly describe the two main links of water rescue-"watching the water" and "on-site first aid"?

Lifeguards should carefully observe the area they are responsible for (commonly known as "watching the water") and constantly observe whether there are drowning "seedlings" on the pool surface and bottom, on the pool surface and on the shore. This is the most important part of life-saving technology. "On-site first aid" Once the drowning person is found, the lifeguard should quickly enter the water, approach, get rid of it, drag it ashore, shoulder it and control the water, give first aid to the comatose person and call 120 for help. Carry out "cardiopulmonary resuscitation" for drowning people whose breathing and heartbeat have stopped, that is, artificial respiration. After cardiopulmonary resuscitation, cover the drowning person with a towel to keep warm, rest on his side, drink hot sugar water to supplement calories, and pay attention to air circulation. If the rescue of cardiopulmonary resuscitation is not ideal and it is impossible to contact the 120 emergency center, it should be sent to the nearest hospital with rescue conditions. During this period, the drowning person can be patted on the back with a hollow fist, which plays the role of chest compression with a rhythm of 80 times per minute until it is sent to the hospital.
