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

Understanding Pulmonary Hypertension The human body is a very complex organism composed of different types of systems and functions. All the functions that each system has‚ is what makes possible for the body to obtain life. One of the most important systems in one’s body is the circulatory system‚ where the heart‚ the lungs‚ and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body’s circulatory system

Hypertension Hypertension also known as high blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems‚ such as heart disease. Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries‚ the higher your blood pressure. High blood pressure is the leading cause of stroke

Hypertension Hypertension is one of the most common worldwide diseases afflicting humans. Because of the associated morbidity and mortality and the cost to society‚ hypertension is an important public health challenge. Over the past several decades‚ extensive research‚ widespread patient education‚ and a concerted effort on the part of health care professionals have led to decreased mortality and morbidity rates from the multiple organ damage arising from years of untreated hypertension.

Explaining hypertension to a 63-year old man with an 8th grade education: Hello sir‚ the doctor wanted me to come in and talk to you for a minute. I understand that u have just been diagnosed with hypertension. I want to make sure you understand what that is and what goes along with it. Hypertension is just our fancy word for high blood pressure. Blood pressure is the amount of pressure that your blood is putting on the walls of your arteries. Now most people don’t even realize they have high

Hypertension Normal ABP : the pressure exerted by blood on the vessel wall of the arterial system from the beginning of the aorta to the start of the arterioles‚ it is about 120 mmHg systolic and 80 mmHg diastolic. Arterial blood pressure (ABP) = cardiac output (CO) X total peripheral resistance Hypertension : sustained elevation of the systemic ABP > 139 mmHg systolic & > 89 mmHg diastolic. Therefore : so long as CO is constant is relatively constant ; a change in the ABP is mainly due

Running head: Hypertension and Preventive Care Hypertension and Preventive Care Hypertension is a chronic disease and is a precursor to many serious adverse events such as stroke‚ heart failure‚ and myocardial infract. Supportive care and preventative care models can treat and minimize the potential adverse effects of hypertension. The purpose of this paper is to describe changes that can be made by nurses and organizations to move from supportive care to preventative care. Utilizing

CHAPTER NO.1 INTRODUCTION HYPERTENSION: INTRODUCTION: This means abnormally elevated blood pressure. It may refer to increase blood pressure in any blood vessels‚ such as pulmonary or portal hypertension. However‚ it usually refers to an elevated systemic arterial blood pressure. Hypertension is not a disease but physical finding. 1.1 DEFINITION: Hypertension may be define as either a sustained systolic blood pressure (SBP) of greater than 140 mmHg or a sustained diastolic
