Potential evapotranspiration (PET) is the amount of water that would be evaporated and transpired if there were sufficient water available. This demand incorporates the energy available for evaporation and the ability of the lower atmosphere to transport evaporated moisture away from the land surface.
In many cases of hospital births where the baby has passed meconium before birth, a special NICU team will be called when the baby is delivered in case there was ingestion of the meconium into the babyâs lungs. If a newborn does swallow some meconium it can lead to Meconium aspiration syndrome (MAS).
While there is always speculation that castor oil also causes the baby to pass meconium, itâs my understanding that castor oil does not cross the placenta, so the slight increase in meconium with castor oil-induced births may instead be linked to its popularity after 40 weeks of pregnancy.
