Because saline, often called salt, contains a lot of sodium. Sodium is very bad for you because it increases your blood pressure. When your blood pressure increases, your arteries and organs can be harmed.
hypertonic effect
Normal Saline 0.9% is called an isotonic solution. A 0.0% saline solution is called a hypotonic solution. A solution of this concentration would cause water to diffuse into the red blood cells and cause them to burst open. A 10% saline solution is called a hypertonic solution. A solution of this concentration would cause water to diffuse out of the red blood cells, making them shrivel up and shrink.
0.35% saline
To make a 9 percent saline solution, start by preparing a 100 percent salt solution. With a bottle of 100 percent salt water, take 9 percent and dilute with distilled water to make a 9 percent saline solution.
This is a isotonic saline solution.
Saline solution should always be in given as a concentration of 0.9% sodium chloride (NaCl).
0.9%
yes it is isotonic solution.
This is an isotonic saline solution; 9 g/L sodium chloride solution in water with added glucose.
Yes this saline is a hypertonic solution but 3% saline is also not normal. There is nothing "normal" about it. There is only one "normal saline" and that is 0.9%.
If you think to an isotonic solution the concentration is 0,9 g NaCl/100 g solution.
Sodium chloride 0.9 percent and normal saline are not quite the same solution. While they share the same osmolality, sodium chloride contains more salt.
