①First aid（急救）plays an important part in saving people's lives. With the development of technology, it is becoming easier and faster. Technology not only makes our lives better, but also can save our lives more quickly. People who have sudden health emergencies, like heart disease or accidents, may only have a few minutes to survive if they don't get help. We can use technologies to offer help faster. Let's look at some technological inventions that are helping save others' lives.
A smart app
②Some people in the US make an app called Pulse Point. The app invites common people trained in CPR（心肺复苏术）to use it. The app knows where the users are. If someone needs first aid nearby, a user can get a message asking them for help.
The magic gel（凝胶）
③The gel can stop a wound from bleeding within 10 seconds. It is made from plants. It can cover a wound and help protect it. It was invented more than 10 years ago but was only allowed to be used on animals at that time. Now in the US, it has been allowed to be used on humans, too. And the inventor from the US was only 17 years old when he invented the gel!
The flying aid
④If people get injured or need help in hard-to-reach areas, drones（无人机）can be of great use. Because they can fly, drones can often offer help faster than people. And they can also make rescue operations safer for rescuers（救助者）working in dangerous conditions. The drones can have a camera that can watch your health. They can also carry useful things like blankets or a life jacket to save someone from drowning（溺死）.
