Simply put, women suffering from cardiac arrest in a public setting are less likely to get lifesaving CPR from a passerby than men are, researchers reported, UPI wrote.
Senior study author Dr. Benjamin Abella, director of the University of Pennsylvania's Center for Resuscitation Science, said, "When it comes to life and death, we need to reassure the public that we're not worrying about what seems socially inappropriate or taboo.
"The situation requires action, and it requires people to not hesitate. A life is on the line.”
But the study showed people do hesitate, especially when the victim is a woman. About 45 percent of men who suffered cardiac arrest in a public setting received CPR from a bystander, compared with only 39 percent of women, the researchers found.
The investigators suspect bystanders might be worried about touching a strange woman's chest in public, even if it is to save a life.
The reason the researchers believe that is because people acted very differently when a woman collapsed at home, where she had an equal chance of receiving CPR.
The study involved data gathered by the Resuscitation Outcomes Consortium, a network of US and Canadian hospitals studying cardiac arrest.
Cardiac arrest can kill a person within minutes if CPR isn't performed, according to the American Heart Association (AHA).
More than 350,000 cardiac arrests occur outside of a hospital each year. Nine out of 10 of these victims die, but speedy CPR can double or triple the chance of survival, the AHA noted.
The researchers reviewed more than 19,000 cases of cardiac arrest that occurred outside of a hospital between 2011 and 2015.
Men in public settings were 23 percent more likely than women to receive bystander CPR, and they also had 23 percent better odds of survival, according to the report.
Study author Audrey Blewer, an assistant director for educational programs at UPenn's Center for Resuscitation Science, said, “But, when we looked in the home, there was no difference in terms of response by gender in the home.”
Dr. Clifton Callaway, executive vice chair of emergency medicine at the University of Pittsburgh Medical Center, added, “The difference between men and women is unexpected.
"I really would have thought if somebody is on the ground, and not responsive, that people would be equally likely to help a man or woman.”
Bystanders already have a difficult time responding to a sudden collapse in public, Abella explained.
They're shocked by the collapse, and often are afraid of hurting someone by attempting CPR.
Abella said, "We think these data show yet one more barrier that may be playing a role in low bystander CPR response.”
The researchers found that, in all cases, bystanders administered CPR only 37 percent of the time.
The study was scheduled for presentation Saturday at the AHA's annual meeting, in Anaheim, California.
Research presented at meetings is typically considered preliminary until published in a peer-reviewed journal.
Callaway said, "The most striking thing to me is how few people get CPR overall.
"Those numbers are something we really need to turn around. Two-thirds of people don't get a bystander to do CPR when their heart has stopped. This is something we've known for decades."
Abella said, “Witnesses should immediately call emergency medicine service line and then start hands-only CPR on the person — one hand over the other on the middle of the chest, pushing hard and fast, at about 100 to 120 beats a minute.
Blewer added, “CPR can be performed through any sort of clothing.
“Don't worry about any undergarments — just start pressing on the middle of the chest.”
Abella noted, “Passersby worried about providing CPR should keep in mind that all 50 states have Good Samaritan laws on the books that will protect them against legal action.
"That's something I think people are not as aware of as they should be.”
