Hypotension In physiology and medicine‚ hypotension is abnormally low blood pressure‚ especially in the arteries of the systemic circulation. It is best understood as a physiological state‚ rather than a disease. It is often associated with shock‚ though not necessarily indicative of it. Hypotension is the opposite of hypertension‚ which is high blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. If it is lower than normal

Abstract Hypotension is one of the top three most frequent causes of cardiac arrests in the United States. One early intervention used in treating hypotension is placing patients in Trendelenburg position. The purpose of this research was to review information on the use of the Trendelenburg position or variations of it to determine whether this position has an impact on hemodynamic status‚ to describe historical practices of the Trendelenburg position‚ state the reasons and need for possible change

1. Provide a brief explanation of what orthostatic hypotension is and identify the vital signs and their values that define orthostatic (postural) hypotension. Orthostatic hypotension is when a person’s blood pressure decreases whenever they go from a lying position to sitting up or standing. This is due to blood leaving the core of the body (organs) and shunts to the peripheries due to vasodilation. This usually makes the patient feel dizzy or light-headed and can cause a patient to become unsteady

Improving Outcomes in Sepsis Patients in the Emergency Department Sepsis is a left threatening illness that affects millions of people each year. The Center of Disease Control reports sepsis as the 10th leading cause of death in the United States (V). For adults age 65 and over hospital admission because of sepsis have increased 48%.

related to vasodilation such as headache‚ dizziness‚ peripheral edema‚ and flushing. Immediate-acting forms of nifedipine can cause reflex tachycardia. To avoid rebound hypotension‚ the drug should be discontinued gradually. In rare cases‚ nifedipine may cause a paradoxical increase in anginal pain‚ possibly related to hypotension or heart failure.Contraindications: the only contraindication is prior hypersensitivity to nifedipine.INTERACTIONSDrug- Drug: when given concurrently‚ other antihypertensives

Case Study: #1 Mr. O’Brien 1. Which clients are at greatest risk for falls in the acute care setting? Consider physiological and environmental risk factors for falls. The majority of patient falls occur in patients who are young and the older adults. Individuals who are ill or who become injured are at risk. If a patient is weakened or has an altered mental state‚ they are susceptible to falls. 2. Identify seven areas of a fall risk assessment. History of falls‚ seizures or fainting‚ older than
