Hypotension - 953 Words

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, then it is called low blood pressure or hypotension. Hypotension is generally considered to be systolic blood pressure less than 90 millimeters of mercury (mm Hg) or diastolic less than 60 mm Hg However in practice, blood pressure is†¦show more content†¦Orthostatic hypotension is indicated if there is a drop in 20 mmHg of systolic pressure (and a 10 mmHg drop in diastolic pressure in some facilities) and a 20 beats per minute increase in heart rate. Neurocardiogenic syncope is a form of dysautonomia characterized by an inappropriate drop in blood pressure while in the upright position. Neurocardiogenic syncope is related tovasovagal syncope in that both occur as a result of increased activity of the vagus nerve, the mainstay of the parasympathetic nervous system. Another, but rarer form is postprandial hypotension, a drastic decline in blood pressure which occurs 30 to 75 minutes after eating substantial meals. When a great deal of blood is diverted to the intestines to facilitate digestion and absorption, the body must increase cardiac output and peripheral vasoconstriction to maintain enough blood pressure to perfuse vital organs, such as the brain. Postprandial hypotension is believed to be caused by the autonomic nervous system not compensating appropriately, because of aging or a specific disorder. TREATMENT: The treatment for hypotension depends on its cause. Chronic hypotension rarely exists as more than a symptom. Asymptomatic hypotension in healthy people usually does not require treatment.

Discussion Previous studies found that water ingestion improved haemodynamic responses to gravitational stress serving as therapeutic relief against hypotension that can be debilitating for most patients. We hypothesized due to the fact that vitamin water is hypotonic in nature like water then it is likely to illicit the OPR to fuel inadequate sympathetic drive and help with symptoms like dizziness upon standing. However the effect of 500ml of water and vitamin water from the current studyRead MoreUnit 4222-335 Undertake physiological measurements1165 Words   |  5 Pagespressure known as hypertension, is 140/90 or more, who chances increase as you get older, overweight, having a relative with high blood pressure, non-eating healthy, which puts us at risk of a heart attack or stroke. The low blood pressure known as hypotension, is 100/60 or less, can drop from a post operation, not drinking enough, quick stand can make you dizzy. The normal limits of blood pressure is between 100/60 to 140/90 . Systolic blood pressure is when an force of heart pumping causing strain andRead MoreSepsis a Case Study3119 Words   |  13 Pagescapillary refill time. Schmidt and Mandel (2008) suggest this is a sign of hypoperfusion as the skin is vasoconstricting due to the redirection of blood flow to the core organs. I informed the doctor and expressed my concerns regarding the patient’s hypotension. A 250ml fluid bolus of colloid was given as an attempt to improve Mr X’s blood pressure and MAP.

Most often, syncope indicates inadequate cerebral blood flow due to hypotension, as might follow haemorrhage or emotional distress (Marieb, 1998). Syncope usually occurs when mean arterial pressure falls below 60mmHg (Marieb, 1998), and in the case of this patient her final blood pressure on arrival at hospital was 62/39, indicatingRead MoreThe Overwhelming Infection of Septic Shock980 Words   |  4 PagesKleinpell states, â€Å"Septic shock is the result of an overwhelming infection, leading to hypotension, altered coagulation, inflammation, impaired circulation at a cellular level, anaerobic metabolism, changes in mental status and multiple organ failure (as sited in Garretson Malberti, Ignatavicius and Workman (2009), â€Å"sepsis is a widespread infection coupled with a more general criteria: body temperature higher than 380C or lower than 360C, heart rate greater than 90 beats per minute, respiratoryRead MoreSepsis Is A Poisoning Of The System By Disease Carrying Bacteria And Their Toxins Absorbed Into The Bloodstream1397 Words   |  6 Pages 4.

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 changeRead MoreSepsis: Early Detection and Implementation of Sepsis Resuscitation Bundle1200 Words   |  5 Pagesvenous access should be obtained and blood cultures drawn immediately, as well blood compatibility. Broad-spectrum antibiotics should then begin within three hours of emergency room admission or within one hour from non-emergency admission. For hypotension or a serum lactate level 4 mmol/L there would be rapid fluid resuscitation with crystalloid or colloid solution to restore mean arterial pressure to 65 mmHg, a central venous pressure of 8-10 mmHg, and urine output 0.5 mL/kg/hr.

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 antihypertensivesRead MoreThe Prevalence Of Low Blood Pressure1645 Words   |  7 Pagesabnormal blood pressure could increase dementia occurrences. The null hypothesis, by default, is the assumption that such incidents of low blood pressure will have no impact on the development of dementia. Any conjoined occurrences of postural hypoten sion and dementia are assumed to be mere coincidence. To conduct the study, researchers from the institute tracked 6,000 people over a range of timespans that averaged 15 years; likely, this fluctuation was due to premature death or withdrawal from
