Technology is helping people to give first aid. It helps save lives faster. Technology not only makes our lives easier, it can also save lives. People who have sudden health emergencies (紧急情况) like heart disease or accidents may only have a few minutes to live unless they get help. We can use technology to offer help faster. Let's look at some technological inventions that are helping save lives.
Smart app
Some people in the US made an app called Pulse Point. It invites common people trained in CPR (心肺复苏术) to use it. The app knows the users' locations. If someone needs first aid nearby, a user will get a message asking them to help.
Magic gel (凝胶)
The gel can stop someone bleeding (流血) in just 10 seconds. It is made from plants. It can stick to a wound and help seal (密封) it. It was invented more than 10 years ago but was only allowed to be used on animals. Now in the US, it has been allowed to be used on humans, too. And the person from the US was only 17 years old when he invented it!
Flying aid
If 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 helping people safer for rescuers (营救者) 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 (溺水).
