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).
What is meconium aspiration? Meconium aspiration occurs when a baby breathes in amniotic fluid containing meconium (the baby's first stools). Before or during labor, the fetus sometimes passes the meconium stool into the amniotic fluid. It is not clearly understood why this happens. It may be a natural event, but it is also thought to be related to fetal distress in some babies.
