Usage: technical; medical/scientific; abbreviated as mOsm or mOsmol

Examples

• The patient's serum osmolality was measured at 290 milliosmols per kilogram of water.
• Normal blood plasma has an osmotic concentration of approximately 300 milliosmols per liter.
• The IV solution was formulated to match the milliosmol concentration of human blood.
• Doctors use milliosmol measurements to assess kidney function and electrolyte balance.
• The dialysate solution contained 300 milliosmols of dissolved particles per kilogram.
