defect is bigger‚ symptoms are more pronounced. A larger volume of oxygenated blood in the left atrium flows back in the right atrium rather than being pumped out of the heart to the rest of the body. Treatment is often necessary. Ventricular Septal Defect A ventricular septal defect (VSD) is similar to an ASD. The difference is that the hole is located between the two ventricles (lower chambers of the heart). The effect is essentially the same. Oxygen-rich blood that would otherwise be pumped into

Introduction Crash carts are very important in the medical field. They provide many advantages and little to no disadvantages when it comes to providing for the medical staff. Not only do they provide the necessary tools needed to take care of several different circulatory and respiratory complications but also have the necessary medications neatly organized for easy access. After concluding my research I found out a lot of interesting facts about not only the items that area inside the cart but

Anticoagulants are considered more aggressive drugs than antiplatelets. They are recommended primarily for people with a high risk of stroke and people with atrial fibrillation. More than 2.7 million Americans have atrial fibrillation (AF)‚ an-arrhythmia of the heart where the atria (the heart’s pumping chambers) quiver instead of beat. As a result‚ not all of the blood is pumped out of the heart‚ allowing pools to collect in the heart chamber‚ where

it is greater than the pressure in the aorta and the pulmonary artery‚ the semi-lunar valves are then forced open‚ this is known as ventricular systole and the blood flows out the aorta and the pulmonary artery and out the heart to around the body and the lungs‚ once this is done the semi-lunar valves close and the ventricles relax‚ this is known as the ventricular diastole. This is repeated causing the heart to pump blood around the body; this is known as the cardiac

heart. If your heart is weak and can’t pump enough blood around your body to keep it working‚ you might need an artificial heart. An artificial heart provides an extra ventricle to help to pump blood around your body that is called ventricular assist device. A ventricular assist device is made from metal and plastic‚ and has a small pumping chamber made by a special material that stops blood clots forming. It may be put into your body or lie outside your body‚ but it depends on what artificial heart
