Nurses need to monitor serum osmolality every 4-6 hours to ensure it is maintained below 360 milliosmole
per liter for 3% hypertonic saline (Kochanek et al., 2012).
Osmolality is a measure of the quantity of osmotically active particles in a solution, expressed as the number of milliosmoles
of solute per kilogram of solvent (mOsm/kg) .
Results were reported as milliosmoles
per kilogram of water (mOsm/kg), with higher values indicating a more concentrated sample (Yeh et al.
The units are in milliosmoles
, except for nitrogen, which is total nitrogen in milligrams.
The osmolarity of these solutions was adjusted to 300 milliosmoles
by adding Ringer solution.

Osmolality, the concentration of solutes, is usually measured in milliosmoles
(mOsm) per liter per volume.
