An In-Depth Look at Portal Hypertension Portal Hypertension (PH) is an increase in the pressure within the portal venous system. The portal venous system is a network of veins that carry blood from the digestive organs to the liver. The most common cause of PH is cirrhosis of the liver. Cirrhosis is an advanced stage of liver scarring called fibrosis. This impedes the liver’s ability to function. PH caused by cirrhosis can often lead to the restored patency of a certain ligament of the liver called

pressure causes the left ventricle to hypertrophy which also puts pressure on the left atria. Atrial pressure is meant to be low so when ventricular pressure rises‚ it ends up transmitting pressure all the way back to the pulmonary venous circuit. The pulmonary venous system is normally meant to bring oxygenated blood back to the left side of the heart and so the backflow of blood creates an increase in hydrostatic pressure in the pulmonary capillary beds. The hydrostatic pressure then exceeds vascular

Main point: Acute respiratory distress syndrome affects over a million people and has a high mortality rate of 34-58% regardless to the improvements in intensive care and ventilatory technologies. The extracorporeal membrane oxygenation (ECMO) is well documented in neonatal and pediatric patients. However‚ the use in adults is very limited. This case presented a successful use of ECMO therapy to treat a patient who had a complex condition and was not effective in traditional treatments. THREE to

Care Plans * 2.1 Risk for Injury * 2.2 Deficient Fluid Volume * 2.3 Excess Fluid Volume In hemodialysis (HD)‚ blood is shunted through an artificial kidney (dialyzer) for removal of toxins/excess fluid and then returned to the venous circulation. Hemodialysis is a fast and efficient method for removing urea and other toxic products and correcting fluid and electrolyte imbalances but requires permanent arteriovenous access. Procedure is usually performed three times per week for

In this condition‚ activation of the left ventricle of the heart is delayed‚ which causes the left ventricle to contract later than the right ventricle.
