Warner says the baby's cause of death was hypertension because the mother's severe internal bleeding caused the fetus to not get enough blood flowing across the placenta causing it to suffocate. So if that's true saying the COD was hypertension makes no sense at all, hypertension is when someone has high blood pressure, if the fetus wasn't getting enough blood it would have low blood pressure, also known as hypotension. But neither of those would be the COD here, if the fetus wasn't getting enough blood and died because of a lack of oxygen then the COD would by hypoxia, which is the technical term for the body's tissues not getting enough oxygen. Saying the COD is asphyxia (suffocation) is also incorrect because asphyxiation is a condition of insufficient oxygen in the body caused by abnormal breathing, and a unborn baby doesn't breathe.
