adell [148]

Fluids used for an intravenous fluid transfusion must be isosmotic with bodily fluids.

Intravenous fluids, sometimes abbreviated as "IV fluids," are liquids that are administered to replace water, sugar, and salt that you may need if you're ill or having surgery and are unable to eat or drink regularly. Through a drip, Intravenous fluids are administered directly into a vein.

In order to treat or prevent dehydration, Intravenous fluids are carefully prepared liquids that are injected into a vein. They are applied to patients of all ages who are ill, hurt, becoming dehydrated from physical activity or the heat, or who are having surgery. Rehydrating intravenously is a straightforward, risk-free treatment that is frequently used.

The law that describes the relationship between pressure and volume of an ideal gas (under constant temperature and amount of substance) is Boyle's law.

It states that pressure is inversely proportional to the volume. This would mean that a graph of P vs 1/V would be a line.

See the attached picture for a graph of P vs V.
