Introduction
Sudden cardiac arrest (SCA) is a medical emergency that requires immediate first aid. English visuals can be powerful tools in providing clear and concise instructions to individuals who may encounter someone experiencing SCA. This guide will provide an overview of essential English visuals for Sudden Cardiac Arrest first aid.
Identifying Sudden Cardiac Arrest
Recognizing the Symptoms
- Loss of consciousness: The person suddenly collapses.
- No breathing: The person does not breathe normally, such as gasping or snoring.
- No pulse: The person does not have a pulse.
Visuals to Use

- Symbol of no pulse: A heart icon with a cross through it to show the absence of a pulse.
Immediate Actions
Calling for Help
- Visual of a phone: An image of a phone with the number to call for emergency services (e.g., 911 in the United States) can remind individuals to call immediately.
Starting CPR
- Illustration of CPR steps: A visual guide to the steps of CPR can be helpful.
- Step 1: Chest compressions: Place the heel of one hand on the center of the person’s chest. Place your other hand on top and interlock your fingers. Keep your elbows straight and use your body weight to push down at least 2 inches (5 cm) deep at a rate of 100-120 compressions per minute.
- Step 2: Open the airway: Tilt the person’s head back and lift the chin to open the airway.
- Step 3: Give rescue breaths: Pinch the nose shut, make a complete seal over the person’s mouth, and blow until you see the chest rise. Repeat until help arrives or the person starts to breathe normally.
