A newborn infant is found dead, abandoned by the road. Among the many questions that the police would like to have answered is whether the infant was born dead or alive. After an autopsy, the medical examiner tells them that the infant was dead at birth. How could the medical examiner determine this?
What will be an ideal response?
Unless the infant was suffocated immediately when it was born, the first breath that it took would start to inflate the lungs and some of the air would be trapped in the lungs. By placing the lungs in water to see if they would float or not, the medical examiner can determine whether or not there is any air in the lungs. Other measurements and tests could also be used to determine whether the infant had taken his/her first breath at all (air in the lungs) or if he/she was dead at birth (lungs collapsed with a small amount of fluid).
