The Science of IV Therapy
About 75% of patients admitted to the hospital are given IV therapy to maintain fluid and electrolyte balance. However, a physician must understand the appropriate theory and perform IV therapy to prevent IV complications. Robertson Wellness and Aesthetics has the right personnel to perform Beverly Hills IV therapy and respond correctly when excesses and deficits manifest.
In the average human body, 70% is fluids which are further distributed into two categories:
1. Intracellular that makes up 1/3 of total body fluids and is located inside the cells.
2. Extracellular contributes 1/3 of total body fluids. Extracellular fluids are found outside the cell and can be:
- Interstitial: These fluids are found in the spaces between cells.
- Intravascular: These fluids are found inside the blood vessels and are also known as plasma.
How fluids are transported in the body
The human body’s homeostatic nature allows it to maintain a constant internal environment even if it continuously interacts with the changing external environment. Fluid balance in the human body takes place through these processes:
- Diffusion: This process involves solutes from a low concentration region, through a semipermeable membrane, to a highly concentrated region.
- Osmosis: This is the transfer of water across a semipermeable membrane, from a region where solutes are lowly concentrated to where they are highly concentrated.
- Filtration: This process involves fluid passage through a filter or a material that allows only specific substances to pass through. Filtration may require the use of pressure.
- Active transport: This is the movement of electrolytes from a low concentration region, against a concentration gradient, to a region of high concentration. In the human body, active transport involves the use of ATP energy.
Why Patients Receive IV Therapy
When the processes involved in fluid transportation in the human body are not enough to maintain balance, physicians provide intravenous therapy to:
- Administer blood, medication, diagnostic reagents, and intravenous anesthetics
- Monitor hemodynamic functions
- Maintain proper nutritional status
Types of IV Therapy
The types of IV fluids varies depending on the purpose of the therapy and include:
- Crystalloids: This solution is made up of water with electrolytes and can easily pass through a semipermeable membrane. Although crystalloids immediately pass from intravascular fluid to extracellular, they stay in the interstitial spaces for about 45 minutes before diffusing through intracellular fluids.
- Colloids: Are usually in the form of large protein molecules and are used to increase blood volume by attracting water from the cells into the blood vessels. Because of their large sizes, they cannot pass through capillary walls.
- Blood and blood products: These substances are given intravenously when a patient experiences low levels. In case of severe blood loss, plasma is used to add volume to the blood. For example, low blood cell count, red blood cells, white blood cells, and platelets also require IV therapy to restore levels.
