Examples of osmolality in the following topics:
-
- The solutions must be of proper osmolality and concentrations, otherwise irreversible damage can be caused.
- Normal saline has low osmolality, which can introduce problems, so IV solutions generally have glucose added to maintain a safe osmolality.
- These two values are slightly different; osmolarity is slightly less than osmolality because it does not take into account the weight of the solutes.
- The normal range of osmolality in human blood plasma is 270-310 milli-osmoles/kg.
- Any shift in the osmolality of the ECF will directly impact the ICF and can cause problems with normal cell functions and water volume.
-
- Osmolarity is related to osmolality, but is affected by changes in water content, as well as temperature and pressure.
- In contrast, osmolality is unaffected by temperature and pressure.
-
- Water flows from the filtrate to the interstitial fluid, so osmolality inside the limb increases as it descends into the renal medulla.
- At the bottom, the osmolality is higher inside the loop than in the interstitial fluid.
