Is this because the crash dummies they have used for many years to assess the safety of cars were based on men’s physiology? Because every time I do refresher training for resuscitation at work, I always wonder why the resus dummies don’t have breasts, or pregnant bellies - because CPR on that kind of different physiology is a different feel. We get infant and paediatric dummies - but always based on men physiology. It always seems like such an oversite and such a disadvantage to women.
