Shunt

the preliminary experiment was to decide on an appropriate length to keep the paper constant at, and an appropriate shunt for the ammeter. The layout and format is the same as the main experiment (see later). We tested the various ammeter shunts, and decided to use the 10mA shunt, as it gave a reading in the middle of the scale, whereas the other shunts had given readings off or almost off the scale. We also found that 32.5cm was the optimum length for the paper, as it

The calculation of the intracardiac shunt ratio between the pulmonary and systemic circulation can determine the size of the shunt. The stroke volume in a normal heart is equal across the four cardiac valves, therefore equal on the right and left sides of the heart. However, when an intracardiac shunt is present the stroke volume of one side of the heart exceeds the stroke volume of the other side of the heart. Typically the intracardiac shunts are directed left-to-right due to higher pressures in

When searching for a topic, this specific story stood out to us: the incredible journey of three surgeons who overcame personal and societal obstacles and created a procedure that gave hope to “blue babies”. The BT Shunt was a surgery, first performed in 1944, that connected the aorta to the pulmonary artery, sending more blood to the lungs to be oxygenated. This topic was a perfect example of breaking barriers and standing up together to create a life-saving solution originally thought to be impossible

processes of digestion and that the right-to-left shunt serves to provide carbon dioxide to gastrointestinal organs besides the stomach, such as the pancreas, spleen, upper small intestine, and liver The bases of Farmer, Uriona, Steenblik, and Stander’s hypothesis was the peculiar ability of amniotes, excluding birds and mammals, to shunt blood past the lungs. Farmer, Uriona, Steenblik, and Stander wanted to explain why birds and mammals do not shunt blood past their lungs like other amniotes, and

Hydrocephalus remains a signifiant challenge to neurosurgeons the world over, in particular the developing world. The mainstay of management remains the insertion of a ventriculo-peritoneal shunt (VPS). This method is expensive and has significant morbidity and mortality. An ideal treatment method would be to maintain a shunt free environment, however at the same time provide adequate and durable cerebrospinal fluid (CSF) diversion in a cost effective manner. We will explore a novel idea that has the potential

one of the very few that would’ve survived this. At five weeks old, I was diagnosed with a condition known as hydrocephalus. This caused cerebro-spinal fluid to push on my skull. This would’ve resulted in death, but we had a VP shunt inserted to keep me alive. What the VP shunt does is it drains the excess fluid from my brain ventricles down into my abdomen. When I was six months old, I was still unable to even lift my head up on my own, The doctors thought I might not even walk, so they diagnosed me

and was suddenly gaining weight. The doctor described his condition as end of liver stage disease that is preventing proper blood flow through the liver and recommended transjugular intrahepatic portosystemic shunt (TIPS) procedure to be performed. Transjugular intrahepatic portosystemic shunt (TIPS) is a less invasive procedure done by putting a stent in a patient liver connecting portal vein and the hepatic vein in order to relive vascular blood pleasure from the portal vein that can cause portal

of the umbilical cord after birth, the placenta’s low resistance area fades and the peripheral resistance rises in the systemic circulation. The pO2 pressure in the aorta rises due to the blood being oxygenated directly in the baby's lungs. Three shunts in fetal circulation include ductus arteriosus, ductus venosus and foramen ovale. The ductus arteriosus and the foramen ovale both close typically when the newborn takes their first breath due to the opening of the lungs. Circulation bypasses the

ventriculoperitoneal shunt removal. The patient had developed cysts in the brain seventeen years ago in 1998 leading to increased intracranial pressures from accumulation of cerebrospinal fluid. After discovering the brain cysts, the patient underwent a ventriculoperitoneal shunt placement. Two years after the shunt was placed, the patient underwent another procedure for shunt revisions due to complications with infection. Now, the patient is presenting for removal of the shunt.
