Question

why do you think IV fluids administered to patients in hospitals is saline (0.9%NaCl(sodium chloride) an isotonic solution) and not a solution with higher or lower NaCl levels?

Answer 1

In hospital patients are given with blood, because when the concentration of blood seels doen't vary. Silhen blood flrich to the blood with IV fluids Isotonic the solution is isotonic fluid and blood coupu- the concentration of cells vary there deve Male higher lons the given with distcubance. When than 0.9% it a hypertonic. The blood fluid to blood cells and so the becomes hapectonic CS Scanned with cytoplas onerar blood cells comes out the water)

to equilibrate the blood. As in process the call looses the cytoplasms and shounk, and may die When we use Mall lowee than 0.99. it is hypotonic and cause the blood cells to bulge as the to watee entee into cells to gain equilibrions, The Scannboged cells may not perform function. Thats why Dom flunds are given esotonic to blood. annar

* then a cell a placed as isotonic solution (the concentration of solution and innee contents of cell is same) there is no movement of solvent between the call and enternal solution as no concentration difference enists. * When a cell as placed in hypectonic solution (whose concentration is highee compared to inside of cell) the solvent from cell moves to the external environment by means of getting equilibriums with the external solution ... The solvent moves until equilibrium occur and so the cell become flaccid. When a cola cell is placed in hypotonic solution (whose concentrations is wwee compared to innee contents of cell) the solvent from outside move inside to attain equilibriums with cell concentuation (solvent move from outside to inside inside become dolented and outside become more concentrated) and the cell become tragid and increase volume. and outeld more diluted T-cell wall fplasma membrane dawa wembrane Scanited with Cam sorowie Hypectonic Hypotonic
