How to Perform Basic First Aid: Essential Skills Guide

Key Takeaways

  • Hands-only CPR can double cardiac arrest survival rates
  • Cool burns under running water for 10-20 minutes, never use ice
  • Apply direct pressure for severe bleeding and call 911
  • Use RICE method for sprains: Rest, Ice, Compression, Elevation
  • Refresh first aid training every two years

Why Everyone Needs First Aid Skills

Average emergency response time is 7-10 minutes in urban areas and up to 30 minutes rural. The American Red Cross reports approximately 60% of injury deaths occur before reaching a hospital. Basic first aid knowledge empowers ordinary people to save lives.

Wound Care and Bleeding Control

For minor cuts: wash hands, clean wound under running water for 5 minutes, apply gentle pressure, use antibiotic ointment, and cover with sterile bandage. For severe bleeding: call 911, apply direct pressure with clean cloth, don't remove soaked cloths — add layers, elevate above heart level, apply tourniquet only as last resort.

Burn Treatment

First-degree (redness): cool under running water 10-20 minutes, apply aloe vera, take OTC pain relief. Second-degree (blisters): cool 20 minutes, don't pop blisters, apply antibiotic ointment, seek care for burns larger than 3 inches. Third-degree (white/charred): call 911, don't apply water or ointments, cover loosely.

CPR Basics

Hands-only CPR can double or triple cardiac arrest survival. Check responsiveness, call 911, place heel of hand on center of chest, push hard and fast at 100-120 compressions per minute (beat of Stayin' Alive), don't stop until EMS arrives.

Choking Response

For conscious adults: stand behind, wrap arms around waist, make fist above navel, deliver quick upward thrusts until object expelled. For infants: use alternating back blows and chest thrusts.

Recognizing Shock

Signs: pale cold clammy skin, rapid weak pulse, rapid shallow breathing, confusion. Treatment: call 911, lay flat, elevate legs 12 inches, keep warm, don't give food or water.

Sprains and Fractures

Use RICE method: Rest, Ice (20 min every 2-3 hours), Compression, Elevation. For fractures: immobilize, apply ice, control bleeding around the site, seek emergency care.

Building Confidence

Take certified first aid courses from Red Cross or AHA. Refresh training every two years. Practice with family. Keep a well-stocked first aid kit.

Practical Checklist

  • Learn hands-only CPR technique
  • Practice the Heimlich maneuver
  • Know how to control severe bleeding
  • Understand burn classification
  • Recognize signs of shock
  • Keep first aid kit stocked
  • Save emergency numbers in phone
  • Take a certified first aid course

Frequently Asked Questions

Do I need certification to perform first aid?

No certification is required to help someone in an emergency. Good Samaritan laws in all 50 states protect people who provide reasonable assistance. However, certified training improves your skills significantly.

How often should I refresh my first aid training?

The American Red Cross recommends refreshing first aid and CPR training every two years to maintain skill proficiency.

Should I move an injured person?

Generally no, unless they are in immediate danger (fire, traffic, structural collapse). Moving someone with a spinal injury can cause paralysis.

When should I use a tourniquet?

Only for life-threatening limb bleeding that cannot be controlled with direct pressure. Place it 2-3 inches above the wound and note the time applied.

Is mouth-to-mouth required for CPR?

Hands-only CPR (compressions without breaths) is recommended for bystanders and is nearly as effective as conventional CPR for adult cardiac arrest.
