Arteriovenous Hemofiltrations are medical procedures that filter blood outside the body. The spelling of this word can be explained using IPA phonetic transcription. The first part, "arteriovenous," is pronounced as "ɑːtɪrɪoʊˈviːnəs," where "ɑː" represents the "ar" sound, "ɪ" represents the "i" sound, and "ʊ" represents the "u" sound. The second part, "hemofiltration," is pronounced as "ˈhiːməʊfɪlˌtreɪʃn," where "i" represents the "e" sound, "əʊ" represents the "o" sound, and "ɪ" represents the "i" sound. Knowing the IPA phonetic transcription of this word can help with correct
Arteriovenous hemofiltration (AVH) is a medical procedure that involves the continuous removal of fluids, waste products, and electrolytes from the blood through a filtration process. It is a form of renal replacement therapy that helps to support kidney function in patients with severe kidney failure.
During arteriovenous hemofiltration, blood is withdrawn from an artery, usually in the patient's arm or leg. The blood is then directed through a specialized filter known as a hemofilter, which is designed to remove toxins, excess fluids, and electrolytes from the bloodstream. The purified blood is then returned to the patient's body through a vein.
This procedure works on the principle of diffusion and convection. Diffusion allows for the movement of waste molecules across a concentration gradient, while convection involves the removal of large fluid volumes by using hydrostatic pressure. Together, these processes effectively cleanse the blood of impurities.
Arteriovenous hemofiltration is predominantly used in critically ill patients who require continuous renal replacement therapy. It is particularly beneficial for individuals with acute kidney injury, fluid overload, or electrolyte imbalances. By eliminating excess fluid and reducing toxin levels in the blood, AVH helps to maintain fluid balance, correct electrolyte disturbances, and potentially improve overall patient outcomes.
The monitoring and management of AVH are performed by a team of healthcare professionals, including nephrologists and specially trained nurses. Careful attention is given to fluid and electrolyte balance, blood pressure, and patient comfort throughout the treatment.
The term "arteriovenous hemofiltration" is derived from the combination of several medical terms.
1. Arteriovenous: The word "arteriovenous" is made up of two parts - "arterio" and "venous". "Arterio" refers to artery, a blood vessel that carries oxygenated blood away from the heart, while "venous" refers to the veins, which carry deoxygenated blood back towards the heart. Together, "arteriovenous" indicates a connection between an artery and a vein.
2. Hemofiltration: "Hemofiltration" is a term that describes a medical procedure done to remove waste products and excess fluid from the blood. It involves filtering blood through a membrane to separate the unwanted substances.
