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).
Meconium is passed into the amniotic fluid in about 10 percent of births. It usually occurs in babies born at term (37 to 41 weeks) or post-term (after 42 weeks). Meconium particles in the amniotic fluid can block small airways and prevent the exchange of oxygen and carbon dioxide after birth.
