Priyanka Kumari: IV Fluids and Isotonic Solution
Priyanka Kumari, Chemistry Teacher at Superprof, shared a post on LinkedIn:
“A small mistake in the salt concentration of an IV fluid can damage red blood cells.
Patients who cannot be fed orally receive fluids through IV infusion. These solutions must be carefully formulated to remain isotonic with the body’s cells.
- Isotonic solution: RBCs remain healthy
- Hypotonic solution: RBCs swell and may burst
- Hypertonic solution: RBCs shrink
Understanding osmosis isn’t just for exams—it’s essential in real-world medicine.”
