One might consider that every day (after viability) that the fetus is in utero is a day in which fetal development occurs and represents one day less that the fetus would have to be in the neonatal ICU (NICU).[13] A 2005 study found the average cost of medical ventilation for adults in the ICU to be $1,500 per day and long-term ICU care to be approximately $5,000 per day.[14] Of the twelve viable children known to be delivered from brain dead mothers on prolonged somatic support between 1982 and 2010, the mean gestational age at the time of brain death was 22 weeks and the mean gestational age at delivery was 29.5 weeks, leading to an average length of somatic support for the mothers in the ICU of 7.5 weeks (52.5 days).[3]
