New Research Reveals Back Blows Are Best for Choking Emergencies

Choking is a critical emergency that demands immediate action to prevent serious consequences, including loss of consciousness or death. Recent research from a team of Canadian researchers has established that delivering back blows is the most effective method for treating someone who is choking. This finding has the potential to change first aid training protocols across North America.

The study revealed that back blows successfully cleared airway obstructions in 72 percent of cases examined in Alberta. This is significantly higher than the effectiveness of abdominal thrusts, which cleared obstructions in 59 percent, and chest thrusts at just 27 percent. Furthermore, the survival rate for patients who initially received back blows was 97.8 percent, even when accounting for factors such as age and the type of obstruction.

The urgency surrounding choking incidents is underscored by alarming statistics. If the airway obstruction is not resolved before emergency services arrive, the risk of death increases by 42 percent. Bystander intervention plays a critical role in the outcome, making public knowledge of effective techniques essential.

New Guidelines from the American Heart Association

The American Heart Association (AHA) has recently updated its guidelines for treating choking, marking the first revision since 2010. This update was influenced by the findings of the Canadian study, which was cited as the sole research directly comparing various choking techniques. Historically, abdominal thrusts were favored based on anecdotal evidence, despite the associated risks of serious injury.

The revised guidelines now advocate for the use of back blows as the first response to choking. The AHA, in collaboration with the Heart and Stroke Foundation of Canada, aims to disseminate this life-saving information across North America.

In practical terms, if an individual is choking but can still cough or speak, they should be encouraged to lean forward and cough forcefully. For those who cannot make any sound, the recommended first step is to deliver five strong back blows between their shoulder blades using the heel of the hand. If these do not resolve the obstruction, abdominal thrusts should then be employed.

Considerations and Emerging Technologies

It is crucial to call emergency services early during a choking incident. If alone, individuals should place their phone on speaker mode to maintain communication while administering first aid. Special considerations should also be taken for children and infants, adapting techniques to their size and capabilities.

Innovative devices like LifeVac© have gained attention for their potential to assist in choking emergencies. These devices generate negative pressure to suction out obstructions. Preliminary data indicates successful outcomes with minimal associated injuries. However, major resuscitation organizations, including the AHA, have not yet endorsed these devices, citing concerns that their use might delay traditional lifesaving techniques.

Training in emergency response for choking incidents has lagged behind similar initiatives for cardiac emergencies. Increased public education on simple, effective techniques, particularly back blows, could significantly improve survival rates.

Researcher Cody Dunne and his team emphasize the importance of widespread training in these techniques. The study received funding from the Canadian Institutes of Health Research and highlights the urgent need for bystanders to be equipped with the knowledge to respond effectively.

As choking incidents can occur at any time, knowing how to respond can mean the difference between life and death. Increased awareness and training could pave the way for more lives saved in choking emergencies.
