When someone can't breathe, the order of your actions matters. A common question in first-aid classes is whether you should use back blows or abdominal thrusts — as if you had to pick one. Modern first-aid guidance answers clearly: you use both, in a deliberate sequence, because each technique works in a different way and together they clear far more blockages than either alone.
Understanding why the sequence exists helps you act with confidence instead of hesitating. This article explains what each technique does, the recommended order for adults and children over one year, and how to keep going calmly until the airway is clear or help arrives. This is general information, not medical advice — hands-on training is the best way to build real skill.
Start with back blows
Lean the person forward and deliver up to five sharp blows between the shoulder blades with the heel of your hand. Gravity and the impact together help dislodge the object.
Follow with abdominal thrusts
If back blows don't work, give up to five abdominal thrusts. Then alternate: five back blows, five thrusts, repeating until the airway clears or the person becomes unresponsive.
Why combine them
Each technique works differently. Back blows create a sharp external force; thrusts raise internal pressure below the blockage. Together they cover more scenarios than either alone.
