Osmolal gap is the difference between the measured osmolality and a calculated osmolality
based on the major commonly measured osmotically active particles. The perceived gap …

Background Many different equations have been previously described to estimate plasma
osmolality. The aim of this study is to compare 14 of these equations, in order to determine …

Background Plasma osmolality is a physic and chemical property of interest in emergency
medicine. This magnitude can be measured at the laboratory, but it is usually estimated with …

The present clinical use of serum osmometry is erroneous in two respects. The first, and the
most important, is the incorrect assumption that serum behaves as a dilute 'ideal'solution …

The osmolal gap (OG) 1 is calculated in the emergency department (ED) when ingestion of
ethylene glycol, methanol, isopropyl alcohol, acetone, or other osmotically active substances …

Background Many studies have assessed the predictive accuracy of serum osmolality
equations. Different approaches for selecting a usable equation were compared using thirty …

Osmolality is a measurement of the number of moles of dissolved particles per kg of solvent
(for clinical purposes, water is the solvent). Osmolarity is a measure of the number of …

OBJECTIVE:: To derive a formula that can be used (i) to calculate osmolality in normal
patients as well as those that are hyperglycemic and intoxicated, and (ii) to predict the …

Background: There are several methods for calculating serum osmolality, and their
accordance with measured osmolality is the subject of controversy. Methods: The …

Purpose Measuring or calculating plasma osmolality is of interest in critical care medicine.
Moreover, the osmolal gap (ie the difference between the measured and calculated …
