Quick Answer: What Does Hypertonic Mean?

What is hypertonic saline used for?

Sodium is the most abundant extracellular ion.

Historically, therapy with hypertonic saline was widely used for a variety of conditions.

Currently, there are 3 primary indications for its use in critical care: hyponatremia, volume resuscitation, and brain injury..

Is salt water a hypertonic solution?

Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

What is an example of isotonic?

Isotonic solutions contain an electrolyte balance similar to plasma in the bloodstream. When an isotonic solution is administered, the fluid volume of the patient is increased without a fluid shift. Common examples of isotonic solutions are 0.9% normal saline and lactated ringers.

Why would you give a patient isotonic solution?

Isotonic fluids Isotonic solutions are used: to increase the EXTRACELLULAR fluid volume due to blood loss, surgery, dehydration, fluid loss that has been loss extracellularly.

What are isotonic solutions give an example?

A solution is isotonic when its effective osmole concentration is the same as that of another solution. This state provides the free movement of water across the membrane without changing the concentration of solutes on either side. Some examples of isotonic solutions are 0.9% normal saline and lactated ringers.

Does hypertonic mean more solute?

Explanation: And since the hypertonic solution is MORE concentrated, it necessarily contains more solute, or LESS solvent than a hypotonic solution .

Does hypertonic shrink or swell?

A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.

What is a real life example of hypertonic solution?

an example of hypertonic is when you put your clothes on a clothesline to dry them off. since the air is hypertonic to the wet clothes, the water comes out and evaporates.

What does hypertonic solution do to the body?

Tonicity in living systems If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell.

When would you use a hypertonic solution?

Used to treat dehydration and decrease sodium and potassium levels. Not administered with blood as it can cause hemolysis of RBCs. Hypertonic solutions have a concentration of dissolved particles higher than plasma and an osmolality > 375 mOsm/L.

What does a hypertonic solution mean?

Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.

What is hypertonic example?

Here are a few examples: Saline solution, or a solution that contains salts, is hypertonic. … A solution of 5% dextrose (sugar) and 0.45% sodium chloride is an example of a hypertonic solution – so is a solution of 5% dextrose and 0.9% sodium chloride.
