Research shows women are 27% less likely than men to receive CPR if they suffer from a cardiac arrest in public. It could be because strangers are reluctant to get "too personal".
They're hoping a new product, the Womanikin, can help get us past that, by reminding us what's at stake.
From the Womanikin website:
When performing chest compressions, locate the end of the person’s breastbone where their ribs come together. Place the heel of one hand 2 inches from the breastbone, closest to the person’s face. Place the free hand on top of the other, interlocking your fingers. Yes, this will mean you are touching her left breast. Don't worry. You might save her life.
