Medically Reviewed on 5/11/2022

What is first aid?

First aid kit
There are a variety of first aid kits. First aid kits may be basic or comprehensive. 

First aid is when you tend to an injured or sick person in need of urgent medical assistance. First aid applies to a broad range of medical situations, which includes

  • specific knowledge and skills (for example, what to do for each type of injury or illness) and
  • the ability to assess a situation and make appropriate decisions (such as when to call for emergency medical assistance)
  • Everyone will need to use a first aid kit at some time.  First aid kits may be basic or comprehensive. Take the time to prepare a kit to have available for home and travel.
  • Always carry your medical information with you.

Do I need a first aid kit?

Preparedness is a key element of first aid. While every home, auto, and boat should be equipped with a basic emergency kit that includes first aid supplies and a first aid manual, special circumstances may necessitate more advanced or specific degrees of preparation for an emergency.

  • For example, residents of certain geographic areas where natural disasters (such as hurricanes, earthquakes, tornados, floods, landslides, or tsunamis) may occur should prepare for emergencies by assembling disaster preparedness kits such as earthquake kits, flood kits, and evacuation kits.

Travelers should also prepare to administer first aid in the region they plan to visit. In many developed countries, this may amount to packing a standard first aid kit and manual with your belongings.

In the developing world or in remote regions, a travel medicine kit should include medicines and supplies that may not be available for purchase as well as any specific products (such as insect repellant to prevent mosquito and tick bites) needed for your destination. It's also important for travelers in foreign countries to learn how to access emergency services by telephone.

Do I need CPR or first aid certification?

CPR is a combination of chest compressions and artificial ventilation (breathing) to save a person’s life.
  • Being prepared to administer effective first aid can also involve learning specific skills such as cardiopulmonary resuscitation (CPR) or abdominal thrusts to assist choking victims.
  • First aid may be required for medical emergencies such as heart attack, stroke, or seizures as well as for minor medical conditions like nosebleeds and mild allergic reactions.
  • Environmental injuries (sunburn, poison ivy, heat exhaustion, frostbite, bee or insect stings) and traumatic injuries (strains, sprains, burns, puncture wounds, and cuts as well as more severe internal injuries) are other situations where first aid skills can be invaluable.
  • Regardless of your level of skill or degree of first aid training, if you find yourself in a true medical emergency, always call 911 for emergency medical assistance immediately.
  • Likewise, if you are involved in any medical situation that is beyond your personal abilities to provide first aid, you should never hesitate to summon emergency medical assistance right away.
