| | Hypotension |
 | | Postural hypotension may occur if someone is taking certain drugs or medicine for high blood pressure. | | | For those with postural hypotension, the blood pressure adjustment is not adequate or it doesn't happen. | | | This is often true of athletes who are in superior shape. |

| | The autonomic reflexes: forgotten aspects |
| | Postural hypotension occurs with any major lesion of the sympathetic efferent fibers (This would be a very good time to refresh your memory of the normal anatomy of the sympathetic nervous system and, as well, the dorsal horn of the spinal cord.). | | | The third relevant reflex system protecting against orthostaic hypotension is the parasympathetic rate of control of the heart that is, in functional terms, not as important. | | | Parasympathetic function may be tested by the bradycardia on carotid massage. |

| | Orthostatic Hypotension in Women: Low Blood Pressure |
| | Therefore, a person with orthostatic hypotension may experience dizziness, changes in vision, and an uncomfortable feeling in the head and neck area upon rising from a lying or sitting position. | | | Many women experience what is called orthostatic hypotension or prostural hypotension. | | | The outside temperature may also play a role in inducing orthostatic hypotension, so staying aware of the heat outside can help in avoiding this condition. |

| | Screening to detect orthostatic hypotension might allow the clinician to make therapeutic changes to prevent these associated problems. | | | Eleven articles were selected on the basis of quality of research methods and applicability to primary care practice from which prevalence, associated factors, and outcomes related to orthostatic hypotension were reported. | | | All studies that we refer to used a postural drop in systolic blood pressure of at least 20 nun Hg as the criterion for orthostatic hypotension. |

| | Evaluation and Treatment of Orthostatic Hypotension |
| | Before a patient with orthostatic hypotension is given any new medication, the benefits of the drug should be carefully weighed against the possible impact of an exaggerated hypertensive response (in the setting of denervation supersensitivity). | | | Orthostatic hypotension due to autonomic failure occurs in patients with a history of chronic alcohol abuse, but only in association with signs of severe peripheral neuropathy (i.e., absent ankle reflexes and diminished sensation in the calves or thighs and hands). | | | The possible relationship between orthostatic hypotension, alcohol use, exercise, meals, or straining should be explored as well. |

| | Hypotension complicating regional blockade |
| | A reduction from 79%-100% to 0-10% has been demonstrated as a result of the use of the left lateral position, intravenous preloading, and vasopressor therapy (2, 3). | | | If hypotension occurs in the mother, her cardiovascular reflexes will act to shunt blood away from non-vital organs (including the uterus). | | | This has the effect of restoring central blood pressure as a means of preserving flow to the vital organs of brain and heart. |

| | Orthostatic Hypotension aHealthyAdvantage |
| | There is no way to prevent orthostatic hypotension, since it is usually the result of another medical condition. | | | If the body's response to a change in vertical position is slow or absent, the result is orthostatic hypotension. | | | Medications designed to keep blood pressure from falling can be used when they will not interfere with other medical problems. |

| | Dizzy When I Stand Up: Postural Hypotension |
| | Dizziness upon standing, from postural hypotension, usually means that either something has gone awry with the circulatory reflexes, or for some reason, the body’s fluid volume is depleted: | | | The net effect is that, if all components of the circulatory reflexes are working properly, the move from lying to standing usually proceeds without symptoms. | | | Although vertigo can be triggered by standing, it's less likely to be vertigo if there's no sensation of the body, or surroundings, moving or spinning. |

| | Postural (Orthostatic) Hypotension |
| | Postural hypotension, also known as orthostatic hypotension, is a condition which results in a decrease in blood pressure when you sit or stand. | | | You will have an increased tendency for postural hypotension if your level of injury is at T-6 or above, but it can occur in all spinal cord injured individuals. | | | After your spinal cord injury, the blood vessels do not decrease in size, in response to lowered blood pressure, due to the altered function of the autonomic nervous system. |

| | Some clinical neurologists prefer to focus on three primary syndromes of the failure or breakdown of the autonomic nervous system. | | | Acute or subacute idiopathic pandysautonomia (ASIP) refers to the breakdown of the autonomic nervous system (control of breathing, blood circulation, pain, taste, etc.) from unknown causes. | | | A defect in this spontaneous response (reflex), prevents the heart rate and blood pressure from rising adequately and orthostatic hypotension results. |

| | Postural Hypotension |
| | Postural hypotension (low blood pressure) is not a disease process, but a condition associated with several different medical problems. | | | This problem is characterised by a temporary drop in blood pressure when there is an abrupt change in body position [when a person stands or sits up from a prone position]. | | | DRUG SIDE EFFECTS (beta-blocker medications, antihypertensives, and diuretics are the common culprits) |

| | Orthostatic hypotension, Eastern Carolina |
| | Orthostatic hypotension is a rapid and sudden decrease in blood pressure that occurs when you change position, such as rising from sitting or lying to standing. | | | When you sit up or stand up, your body adjusts the way it pumps blood to maintain blood flow to your brain. | | | Most people do not have orthostatic hypotension symptoms when they change position. |

| | Autoregulation of cerebral blood flow is generally maintained with age, except in persons who have symptomatic orthostatic hypotension. | | | However, chronic hypertension raises the lowest blood pressure at which autoregulation can maintain cerebral blood flow. | | | Reduced adrenergic responsiveness by the aged heart and vasculature may diminish baroreflex-mediated cardioacceleration and vasoconstriction in response to hypotensive stimuli. |

| | Orthostatic hypotension - Wikipedia, the free encyclopedia |
| | Orthostatic hypotension (also known as postural hypotension and, colloquially, as head rush) is a sudden fall in blood pressure that occurs when a person assumes a standing position. | | | Some drugs that are used in the treatment of orthostatic hypotension include fludrocortisone (Florinef), erythropoietin and midrodrine. | | | The prognosis for individuals with orthostatic hypotension depends on the underlying cause of the condition. |
