What is isotonic fluid?
Isotonik fluid is a fluid which has same composition with our body fluid so its must have equivalent tonisitic pressure level. Tonisitic determine movement of the fluid between cell inside our body. Example : Water will move from an area which has low tonisitic (hypotonic) to others area which has high tonisitic (hypertonic), until tonisitic between both area become equivalent. On the other word, “isotonic fluid” is appropriate to replace loss of fluid as good as our body fluids its self.
