1 . First aid is a crucial aspect of healthcare that can significantly save someone’s life or prevent further injury or illness. Knowing when to use first aid is essential so that proper measures are taken promptly.    1    

Injuries and Accidents

One of the most common instances where first aid is required is in injuries and accidents.    2     In such situations, it is essential to provide immediate care to prevent further damage and ensure that the affected individual receives timely medical attention. Some of the initial steps in first aid for injuries include applying pressure to stop bleeding, immobilizing the affected area, and administering pain relief medication.

Cardiac Arrest (心脏停跳)

Another critical situation where first aid can make a difference is during a cardiac arrest. A cardiac arrest occurs when the heart stops functioning; immediate intervention is necessary.     3     The first step in such a situation is to call emergency services and start cardiopulmonary resuscitation (CPR) until professional help arrives. Knowing how to perform CPR can be life-saving in such situations.

Choking and Suffocation (窒息)

Choking and suffocation are emergencies that can occur at any time, and immediate intervention is necessary to prevent further complications. If someone is choking, it is essential to act quickly.     4     Similarly, if someone is suffocating due to a blocked airway, it is vital to clear the obstruction and ensure that the person’s airway is open.
