Key Updates in Resuscitation Procedure After Drowning

New recommendations on rescuing adults and children who have drowned include an important update for healthcare professionals, trained rescuers, and untrained lay rescuers.
The American Heart Association (AHA) and the American Academy of Pediatrics (AAP) have issued recommendations that highlight delivering rescue breaths as well as calling 911 and performing chest compressions in cardiopulmonary resuscitation (CPR) as first steps when a person pulled from the water is in cardiac arrest.
This is the first collaboration between the two organizations on resuscitation after drowning. The recommendations were published November 12 simultaneously in Circulation and Pediatrics.
Included in the recommendations are two key principles:
Anyone pulled from the water who has no signs of normal breathing or consciousness should be presumed to be in cardiac arrest.
Rescuers should immediately start CPR that includes rescue breathing in addition to chest compressions. Multiple large studies show more people with cardiac arrest from non-cardiac causes such as drowning survive when CPR includes rescue breaths compared with hands-only CPR (calling 911 and pushing hard and fast in the center of the chest).
If someone is untrained, unwilling, or unable to give breaths, they can perform chest compressions until help arrives, the recommendations advise.
Reasoning Behing the Update
Authors, led by writing group cochair Tracy E. McCallin, MD, associate professor in the division of pediatric emergency medicine at Rainbow Babies and Children’s Hospital in Cleveland , Ohio, explain that drowning generally advances from initial respiratory arrest from submersion-related hypoxia to cardiac arrest, and therefore it can be difficult to distinguish respiratory arrest from cardiac arrest because pulses are difficult to accurately palpate within the recommended 10-second window.
“Therefore, resuscitation from cardiac arrest due to this specific circumstance must focus on restoring breathing as much as it does circulation,” the authors wrote.
Resuscitation after drowning may begin in the water with rescue breathing when safely provided by trained rescuers and should continue with chest compressions, once the drowned person and the rescuer are on land or in a boat, the report authors wrote.
“The focused update on drowning contains the most up-to-date, evidence-based recommendations on how to resuscitate someone who has drowned,” McCallin states in a press release. 
In addition to the new guidance on rescue breaths, the update includes new topics that the AHA has not previously addressed with treatment recommendations, such as oxygen administration after drowning; automated external defibrillator use in cardiac arrest after drowning and public-access defibrillation programs.
Pediatricians Can Help Spread the Word
Alexandra Stern, MD, assistant professor in the Department of Pediatrics at University of Florida, Gainesville, Florida, who was not part of the update, says pediatricians can help disseminate this new information.
“Water safety is a topic frequently discussed as a pediatrician, with focus often being on primary prevention of drowning,” she said. “We stress the importance of the multiple layers of protection against drowning, such as touch supervision (staying within arm’s length); secure fencing, access to appropriate life jackets, and teaching our children to swim. Learning CPR is a large part of these measures and continuing these discussions with our patients and families is important.”
She added that updating the recommended procedures will likely require changes to all forms of education and community outreach regarding drowning from basic life support classes to more advanced lifeguard training. She noted that the update provides practical guidance not just for trained rescuers and healthcare professionals, but also for family members. 
The paper notes that drowning is the third leading cause of death from unintentional injury globally, accounting for 7% of all injury-related deaths. In the United States, drowning is the leading cause of death in children aged 1-4 years and the second leading cause of death from unintentional injury in children aged 5-14 years.
The update is based on systematic reviews from 2021 to 2023 performed by the International Liaison Committee on Resuscitation related to the resuscitation of drowning.
