Women Are Less Likely To Receive CPR Than Men. Training On Manikins With Breasts Could Help

(MENAFN- The Conversation) If someone's heart suddenly stops beating, they may only have minutes to live . Doing CPR (cardiopulmonary resusciation) can increase their chances of survival. CPR makes sure blood keeps pumping, providing oxygen to the brain and vital organs until specialist treatment arrives.

But research shows bystanders are less likely to intervene to perform CPR when that person is a woman. A recent Australian study analysed 4,491 cardiac arrests between 2017–19 and found bystanders were more likely to give CPR to men (74%) than women (65%).

Could this partly be because CPR training dummies (known as manikins) don't have breasts? Our new research looked at manikins available worldwide to train people in performing CPR and found 95% are flat-chested.

Anatomically, breasts don't change CPR technique. But they may influence whether people attempt it – and hesitation in these crucial moments could mean the difference between life and death.

Cardiovascular diseases – including heart disease, stroke and cardiac arrest – are the leading cause of death for women across the world.

But if a woman has a cardiac arrest outside hospital (meaning her heart stops pumping properly), she is 10% less likely to receive CPR than a man. Women are also less likely to survive CPR and more likely to have brain damage following cardiac arrests.

These are just some of many unequal health outcomes women experience, along with transgender and non-binary people. Compared to men, their symptoms are more likely to be dismissed or misdiagnosed, or it may take longer for them to receive a diagnosis.

There is also increasing evidence women are less likely to receive CPR compared to men.

This may be partly due to bystander concerns they'll be accused of sexual harassment , worry they might cause damage (in some cases based on a perception women are more“frail”) and discomfort about touching a woman's breast.

Bystanders may also have trouble recognising a woman is experiencing a cardiac arrest.

Even in simulations of scenarios, researchers have found those who intervened were less likely to remove a woman's clothing to prepare for resuscitation , compared to men. And women were less likely to receive CPR or defibrillation (an electric charge to restart the heart) – even when the training was an online game that didn't involve touching anyone.

There is evidence that how people act in resuscitation training scenarios mirrors what they do in real emergencies. This means it's vital to train people to recognise a cardiac arrest and be prepared to intervene, across genders and body types.

Most CPR training resources feature male bodies, or don't specify a sex. If the bodies don't have breasts, it implies a male default.

For example, a 2022 study looking at CPR training across North, Central and South America, found most manikins available were white (88%), male (94%) and lean (99%).

These studies reflect what we see in our own work, training other health practitioners to do CPR. We have noticed all the manikins available to for training are flat-chested. One of us (Rebecca) found it difficult to find any training manikins with breasts.

Our new research investigated what CPR manikins are available and how diverse they are. We identified 20 CPR manikins on the global market in 2023. Manikins are usually a torso with a head and no arms.

Of the 20 available, five (25%) were sold as“female” – but only one of these had breasts. That means 95% of available CPR training manikins were flat-chested.

We also looked at other features of diversity, including skin tone and larger bodies. We found 65% had more than one skin tone available, but just one was a larger size body. More research is needed on how these aspects affect bystanders in giving CPR.

CPR technique doesn't change when someone has breasts. The barriers are cultural. And while you might feel uncomfortable, starting CPR as soon as possible could save a life.

Signs someone might need CPR include not breathing properly or at all, or not responding to you.

To perform effective CPR , you should:

• put the heel of your hand on the middle of their chest

• put your other hand on the top of the first hand, and interlock fingers (keep your arms straight)

• press down hard, to a depth of about 5cm before releasing

• push the chest at a rate of 100-120 beats per minute (you can sing a song) in your head to help keep time!)

You don't need to remove someone's bra to perform CPR. But you may need to if a defibrillator is required.

A defibrillator is a device that applies an electric charge to restore the heartbeat. A bra with an underwire could cause a slight burn to the skin when the debrillator's pads apply the electric charge. But if you can't remove the bra, don't let it delay care.

Our research highlights the need for a range of CPR training manikins with breasts, as well as different body sizes.

Training resources need to better prepare people to intervene and perform CPR on people with breasts. We also need greater education about women's risk of getting and dying from heart-related diseases.
