Soaking in cool water on hot days is something many people long for, but as the saying goes, water and fire are merciless. Human beings are not aquatic animals and should not stay in water for too long, otherwise prolonged hypoxia will lead to death.
1. If you experience leg cramps in the water, you should immediately go ashore, sit down with your legs straight, grab your thumb with your hand, pull it backwards, and massage the calf muscles. If you cannot go ashore immediately, you should remain calm, hold your breath, and do the above actions in the water.
2. When rescuing a drowning person, it is necessary to use lifebuoys, balls, or wooden boards. Except for full-time lifeguards, even those who can swim should not approach the drowning person with their bare hands.
3. After the drowning person is rescued, their breathing and heartbeat should be checked immediately. If breathing stops, artificial respiration should be performed immediately. First, blow four breaths into the mouth to mouth border, and observe if it returns to spontaneous breathing within 5 seconds. If there is no response, artificial respiration should be continued until it returns to spontaneous breathing.
4. If the drowning person’s breathing and heartbeat completely stop, immediate cardiopulmonary resuscitation should be performed.
5. If a drowning person drinks a large amount of water, they can use their knees to support their back, one hand to support their upper abdomen, and the other hand to open their mouth when they are conscious; Or the rescuer should kneel on one leg and have the drowning person face down on their knee to spit water.
6. When stabbed by a fish groove, if only the hook tip is inserted, gently remove it first, then disinfect and bandage it. If the hook is also inserted, do not forcefully pull it out. You can first cut off the connecting line, follow the curve of the fish hook, and continue to thrust into the skin as much as possible, so that the hook tip and barb are exposed to the skin adjacent to the original puncture point. Cut off the barb part, then remove the fish hook, clean the wound and bandage it, and go to the hospital for treatment.
