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).
If the meconium is ingested into the babyâs lungs, three things can occur to the baby; however it does not always happen. 1  Only a third of infants who ingest meconium need breathing assistance. The things that may occur include: 2  blockage of airways. 3  lower gas exchange in lungs. 4  inflamed airways leading to pneumonia.
