Sep 2 2021 Crystalloid solutions are distinguished by the relative tonicity (before infusion) in relation to plasma and are categorized as isotonic
Results 1 - 65 Isotonic hypertonic
The cell membrane is also called the PLASMA membrane and is made of a Label the tonicity for each solution (isotonic hypotonic
The choice of a crystalloid solution is based on the tonicity (or the concentration) of the fluid with respect to the patient's tonicity. If a patient receives
What determines the concentration is tonicity. In comparison to the cell's (or item's) concentration a solution can be isotonic
A. Hypotonic…hypertonic. B. Hypertonic…hypotonic Based on what you know of tonicity the most ... C. sea water is isotonic to your body fluids and you.
Raising the tonicity of the fluid bathing frog atrial trabeculae has and a further rise in contractility on return to isotonic fluid (off response).

Hypotonic solutions are used when the cell is dehydrated and fluids need to be put back intracellularly This happens when patients develop diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemia Important: Watch out for depleting the circulatory system of fluid since you are trying to push extracellular fluid into the cell to re-hydrate it
Describe and differentiate colloid and crystalloid IV fluids Understand osmosis as it pertains to water movement with IV therapy Define tonicity and the actions of isotonic hypotonic and hypertonic crystalloids in the body Identify the three most common IV solutions used in the prehospital setting and classify them as isotonic hypotonic or
Hypotonic • A hypotonic solution shifts fluid out of the intravascular compartment hydrating the cells and the interstitial compartments Osmolarity is lower than serum osmolarity Isotonic • Because an isotonic solution stays in the intravascular space it expands the intravascular compartment Osmolarity is the same as serum osmolarity
with normal hemoglobin to hypotonic fluid decreases cell membrane stiffness 22 Another study which examined RBCs with sickle hemoglobin specifically showed that those RBCs exposed to isotonic fluids had increased stiffness slower transit times and increased propensity to microvascular occlusion
