Isotonic saline solution has no net effect on red blood cells (RBCs) as it has the same osmolarity as blood. This means that RBCs will neither shrink (crenate) nor swell (lyse) when placed in isotonic saline solution. The solution maintains the normal shape and function of the RBCs.

What is the chemical composition of RBC diluting fluid?

RBC diluting fluid commonly consists of an isotonic saline solution containing electrolytes and buffers to maintain the stability of red blood cells during counting. The composition may vary based on the specific laboratory protocol or commercial product used.


What happens if rbc's and saline solutions are mixed?

If red blood cells (RBCs) are mixed with a saline solution, the RBCs may undergo hemolysis, where they rupture and release their contents into the solution. This can lead to changes in the osmotic balance and potentially cause damage to the RBCs. It is important to handle RBCs carefully to prevent hemolysis and maintain their function.


What are the Tonicity of the cell?

Cells can be placed in solutions with higher, lower, or equal concentration to the cell... 1. ISOTONIC: - a solution with equal concentration to the cell. - 0.9% NaCl solutions is isotonic to RBC (red blood cells). - isotonic solutions cause no net gain or loss of water to a cell. 2. HYPOTONIC: - solute concentration is greater on the inside of the cell (or: the outer solution has less concentration than inside). - >0.9% NaCl solutions is hypotonic to RBC (red blood cells). - causes swelling, could burst (lyse) - net gain of water 3. HYPERTONIC: - <0.9% NaCl solutions is hypertonic to RBC (red blood cells). - net loss of water from the cell. - solute concentration is greater on the outside of the cell (or: the outer solution is greater concentration than the inside). - causes the cell shrink (crenation in RBC)


What might happen to human blood cells if placed in a beaker of salt water?

It depends on the concentration of salt within the solution. If the saline solution was less than 0.9%, then water would flow into the cells and they would swell and possible rupture. If the saline concentration was greater than 0.9%, then water would flow out of the cells and shrink which is called crenation. It the saline solution was 0.9% exactly, that is isotonic to the interior of a RBC and nothing would happen.


What is isomotic solution?

iso-osmotic is different to isotonic even though they have the same number of solute particles as in the inside of red blood cells in isotonic solutions movement of water in and out of the cell is the same and RBC's remain unchaged, in iso-osmotic solutions RBC swell and burst this is because the semi permeable cell membrane cannot exclude iso-osmotic solutios as it can other solutes, causing a concentration gradient

Why to use RBC diluting fluid for counting?

You can use any isotonic solution like Normal Saline Solution (NSS), Hayem's and Gower's.


Why do RBC do not burst inside human body?

You have the osmolarity or the osmolality of the blood is equal to the RBC in your blood. That is about 154 millimole or milliosmole, with only slight variation, depending of the water consumption. So the RBC do not burst in your body. They will not burst either, in isotonic or human normal saline. That means in 0.9 % saline solution.


What is the effect of isotonic salt solution on rbc?

Iso means same, therefore the salt solution concentration is the same as the concentration of salt within the blood cells. So nothing happens - the RBC's remain the same (no shrinking/crenating or swelling/lysing)


What iv solution do you hang with blood?

I believe it's Lactated Ringers with the packed RBC's connected to the line by a Y connector.

Why is pnss used in blood transfusion?

Plain Normal Saline Solution or PNSS is used after blood transfusion because it is the only compatible diluent or 'cleaner' after transfusion. Its sole content of Sodium and Chloride does not cause blood reactions that may be dangerous to the client. D5LRS for example is discouraged as it has calcium which is a clotting factor. Introducing D5LRS after blood transfusion may cause massive thrombosis or clotting. sicnarf619 UCC-College of Nursing PH
