Rethinking Choking Response: What Shifting Expert Consensus Means for Everyday Rescuers
For decades, the abdominal thrust — commonly known by the name of the physician who popularized it — stood as the unquestioned gold standard for rescuing a choking adult. Emergency medicine instructors taught it with confidence. Posters in restaurant kitchens illustrated it in step-by-step diagrams. And millions of Americans learned it as the definitive answer to a blocked airway.
That confidence is now being tested.
Across the Atlantic, health authorities in the United Kingdom and Australia have moved away from abdominal thrusts as the first-line intervention, favoring a combination of firm back blows and, if necessary, chest thrusts. In the United States, the conversation is more complicated — and for everyday rescuers committed to being prepared, understanding why the debate exists matters as much as knowing which technique to perform.
Where the Disagreement Began
The tension between abdominal thrusts and alternative techniques is not new, but it has intensified as researchers and clinicians have subjected older recommendations to more rigorous scrutiny. The core question is deceptively straightforward: which mechanical approach most reliably dislodges a foreign object from the airway while minimizing the risk of injury to the person being helped?
Proponents of abdominal thrusts argue that the upward compression of the diaphragm generates sufficient pressure to expel most obstructions. Critics point out that the technique carries a documented risk of internal injury — including damage to the liver, spleen, and aorta — particularly when applied forcefully or repeatedly.
Back blows, delivered between the shoulder blades with the heel of the hand, produce a different kind of pressure dynamic. Some researchers contend that this approach can be equally effective for dislodging soft food obstructions while reducing the likelihood of abdominal trauma. Chest thrusts, which compress the sternum in a manner similar to CPR compressions, offer a third option that avoids the upper abdomen entirely.
The challenge, as emergency medicine physician Dr. Laura Hendricks of the University of Colorado School of Medicine explains, is that the evidence base for all three techniques remains limited by the obvious ethical constraints on conducting controlled trials involving deliberate airway obstruction in human subjects. "We are working with a combination of cadaver studies, case reports, and biomechanical modeling," she notes. "That is a reasonable foundation, but it does not provide the kind of certainty that would settle a debate of this magnitude."
What Major Organizations Currently Recommend
The American Heart Association and the American Red Cross — the two bodies whose guidance most directly shapes first aid training across the United States — continue to include abdominal thrusts in their choking response protocols for adults and children over one year of age. However, both organizations have incorporated back blows into updated training materials, typically recommending a sequence that begins with five back blows followed by five abdominal thrusts, cycling between the two until the obstruction clears or the person loses consciousness.
This combined approach reflects a pragmatic acknowledgment that no single technique works in every situation. It also aligns more closely with the guidance issued by the International Liaison Committee on Resuscitation, which convenes experts from across multiple countries to synthesize global evidence.
By contrast, the United Kingdom's Resuscitation Council explicitly recommends beginning with back blows and transitioning to chest thrusts — not abdominal thrusts — if back blows fail. The rationale centers partly on the injury risk associated with abdominal compression and partly on evidence suggesting that chest thrusts may be comparably effective for many obstructions.
For American rescuers, the practical implication is that credible, evidence-informed organizations have reached different conclusions. This is not a sign that the science is broken; it is a sign that the science is still developing.
Age Matters: Infants, Children, and Adults
One area of near-universal agreement involves infants under one year of age. Abdominal thrusts are contraindicated for this population due to the risk of injury to underdeveloped abdominal organs. The recommended approach for a choking infant involves a specific sequence of five back blows and five chest thrusts, administered while supporting the baby face-down and face-up respectively. This technique is distinct from the adult protocol and requires separate training.
For children between one year of age and puberty, most U.S. guidelines recommend the same general approach as for adults, with modifications in force appropriate to the child's size. The back blow and abdominal thrust combination remains the standard in most American training curricula for this age group.
Pregnant individuals and those with significant obesity present additional considerations. For these populations, chest thrusts are widely recommended as a substitute for abdominal thrusts, since the anatomy of the abdomen makes the standard technique less effective and potentially more hazardous.
The Practical Challenge for Trained Rescuers
Perhaps the most significant consequence of this evolving debate is the confusion it creates for people who have invested time and effort in becoming prepared. A community member who completed a first aid course three years ago may have learned a protocol that differs meaningfully from what their neighbor learned last month. Workplace safety trainers may find that their materials are out of step with the most current organizational guidance.
This is not a reason for discouragement. It is, rather, an argument for treating first aid education as an ongoing commitment rather than a one-time certification. Refreshing your training every two years — the interval recommended by most major certifying bodies — ensures that you are working from current evidence rather than outdated assumptions.
It also reinforces the importance of calling 911 early. In any choking emergency, activating the emergency response system should occur simultaneously with, not after, first aid intervention. Even if a rescuer successfully dislodges an obstruction, the person who choked may require medical evaluation for potential internal injuries or residual airway compromise.
What to Do Right Now
If you are currently certified in first aid, review the specific protocol taught in your most recent course and check whether the certifying organization has issued updated guidance. The American Heart Association and American Red Cross both maintain publicly accessible resources that reflect their current recommendations.
If you are not yet trained, this moment of public debate is an ideal time to enroll in a course. Learning any evidence-based choking response protocol is vastly preferable to having no training at all. A rescuer who confidently applies a slightly imperfect technique will almost always outperform a bystander paralyzed by uncertainty.
Finally, consider sharing what you learn. The gap between what emergency medicine researchers know and what the general public understands remains wide. Conversations at the dinner table, in community centers, and at workplace safety meetings are how that gap closes — one informed neighbor at a time.
The Bigger Picture
The choking intervention debate is, in many ways, a healthy sign. It reflects a medical community willing to revisit assumptions, weigh new evidence, and revise guidance in the interest of better outcomes. The willingness to say "we can do this more safely" is precisely the kind of intellectual honesty that strengthens emergency medicine over time.
For everyday heroes, the takeaway is not that the old techniques were wrong or that the new ones are definitively superior. The takeaway is that staying informed, staying trained, and staying engaged with your community's preparedness education are themselves life-saving acts — before any emergency ever begins.
