isotonic fluid

Isotonic fluids are solutions used in medical treatments that have the same concentration of essential salts and minerals as the fluids in your blood. When administered, they help replace lost fluids and electrolytes without causing shifts between your blood vessels and body tissues. This balance prevents issues like swelling or dehydration. Common examples include normal saline and lactated Ringer's solution. They are typically used for dehydration, blood loss, or to maintain fluid balance during surgery, ensuring that your body's fluid levels stay stable and your cells function properly.
