By Steven MillerDecember 21, 2025

The act of administering a back slap, a simple yet crucial first aid technique, involves a specific part of the hand. This maneuver is often used to help a choking victim, making it a vital skill to understand for anyone learning first aid. Let's delve into the correct hand placement for a back slap, ensuring you're equipped with the right knowledge to assist in an emergency.

Understanding the Back Slap Technique

A back slap is a series of firm, quick slaps on the upper back, typically performed on a choking victim who is coughing but unable to dislodge the obstruction. This technique is designed to help the victim dislodge the foreign object by stimulating a coughing reflex. It's important to note that back slaps should only be performed on a conscious, coughing individual, as they can cause harm to an unconscious or injured person.

The Correct Hand Placement for a Back Slap

To perform a back slap correctly, you'll use the heel of your hand. This part of the hand, located at the base of your thumb, is the most suitable for delivering the necessary force without causing injury. Here's a step-by-step guide to help you understand the process:

Approach the choking victim from behind.
Make a loose fist with your dominant hand, ensuring your thumb is tucked inside.
Position the heel of your hand against the upper back of the victim, just below the shoulder blades.
Deliver a firm, quick slap with your hand, using a slight upward motion to help dislodge the obstruction.
Repeat the process up to five times, allowing the victim to cough in between slaps.

When to Use a Back Slap: The Choking Hierarchy

Back slaps are just one part of the choking hierarchy, a series of techniques used to help a choking victim. It's essential to understand when to use a back slap and when to progress to the next technique. Here's a simple table to help you remember the order:
