ng output is considered part of the fluid output along with urine measurements, so at the end of a shift the ng fluid output is noted (color, consistency), measured and recorded. on some units, the same amount of ng output is replaced with an identical amount of iv fluid over a 4-hour period or so to keep fluid levels in balance.
