Hyperbaric Oxygen Therapy Extends Survival After Cardiac Arrest
FRIDAY, July 25 (HealthDay News) — High-dose hyperbaric oxygen therapy shows promise as a way to extend the window of opportunity to resuscitate a person whose heart has stopped during sudden cardiac arrest, a new study shows.
Researchers at the School of Medicine at the Louisiana State University Health Sciences Center in New Orleans report they used the technique to revive pigs up to 25 minutes after their hearts had stopped beating. In humans, if a patient's heart is not restarted through some means (CPR, medications or electric shock) within 16 minutes, 100 percent of patients die, according to American Heart Association statistics.
Sudden cardiac arrest is the leading cause of death of Americans.
"To resuscitate any living organism after 25 minutes of heart stoppage at room temperature has never been reported and suggests that the time to successful resuscitation in humans may be extended beyond the stubborn figure of 16 minutes that has stood for 50 years," study leader Keith Van Meter, a clinical professor of medicine at the LSU center, said in an university news release.Read entire article...
