Responding to crisis moments by first aid


By Science Columnist Ho-Gwan Ko



Unexpected things happen in life. There is a saying that “if you are unlucky, you break your nose even when you fall backwards.” Accidents take place frequently in everyday life. Young students are no exception. Nobody can be an exception, so it is a good idea to learn first-aid tips.

The most common first aid method you can see in movies or dramas would be CPR (Cardiopulmonary resuscitation). If a person’s heart has stopped for some reason such as a heart attack, people around the person would scramble to perform CPR. If your heart stops beating, then blood stops flowing, not supplying oxygen to organs. Your brain starts to lose its oxygen supply within four to five minutes, and brain cells start dying.

Chest compressions force blood to circulate, supplying oxygen to the brain and prolonging the time the brain survives. Calling 911 does not always mean that medical first responders can get there within 5 minutes; anyone near the victim should perform CPR as soon as possible to increase the chance of survival.

To perform CPR, lay the victim down, protecting the head and neck. Tilt the head backwards to open the airway. Place your hand on top of the other hand and interlock your fingers, and press on the breastbone at the center of the chest with the heel of your hand. Chest compressions should be 5-6 cm deep at a rate of about 100 per minute. CPR should be continued until paramedics arrive at the scene.

The above is a brief summary of how to administer CPR. You need to receive training to do CPR properly. It is very difficult to do it properly, and it is especially hard for a child to provide CPR to an adult. However, it is good to learn it, as CPR is a good method to save people's lives in case of emergency.

▲ Familiarizing yourself with first aid in advance will help you save someone's life in an emergency.

Along with CPR, the Heimlich maneuver is another first aid method which saves a lot of lives. This is performed to clear the airway by forcing an object or food out of the respiratory passage. The term is named after Dr. Henry Heimlich, who first conceived of the technique.

If someone around you has choked on food and is unable to breathe, stand behind the person. Place your arms around the body under the armpits. Make a fist and place it between the navel and solar plexus, with the thumb side in.

Grab the fist with your other hand and give abdominal thrusts. Give them inwardly and upwardly, i.e., diagonally upward thrusts. It is important that you press hard into the chest with a quick thrust instead of doing it slowly. Repeat until the object is expelled from the passage. If you are alone and choking, use the edge of a desk or a chair to apply pressure to your stomach. If the object is not expelled soon enough, your brain will not get oxygen and you could end up losing your life. It is important to perform it quickly.

Some injuries are not life threatening. One example is a mild burn. If you get a burn, do not use any folk remedies. Cool the burned area with cold water and go to a doctor quickly. You should be careful not to let other substances touch the wound until you get treatment.

If you get a foreign object in your eye or ear, do not try to force it out of them. You should shed tears or rinse with clean water. If you have an insect in your ear, shine a light into your ear to draw it out. If you get any chemicals, you should go to a doctor as soon as you know what it is.

For children, it is best to get help from adults. If there is an accident, getting out of a dangerous situation is the number one priority, and you should immediately call 911. First aid should be performed after calling 911. In case you cannot report it yourself, you should ask a specific person nearby to make a 911 call. If you just shout around without designating someone, it is likely that reporting will be delayed.

Although it sounds easy, you are likely to panic when an accident actually happens. If you are well trained in safety procedures and remember the instructions, you will be able to act calmly when an emergency takes place.
