Additionally, it is omitted when the patient is demonstrating hemodynamic instability, [2] which term is generally used to indicate abnormal or unstable blood pressure but which can also suggest inadequate arterial supply to organs. [6] Orthostatic vital signs are also taken after surgery. [7]
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
Labile hypertension occurs when there are unexpected changes in blood pressure.The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90mm Hg or over and returns to its normal range.
Portsmouth sign refers to a situation in which the systolic blood pressure (SBP) reading (measured in mmHg) falls below that of the heart rate (HR) (measured in beats per minute). It typically signifies a worrying clinical prognosis, specifically caused by shock .
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Permissive hypotension or hypotensive resuscitation [1] is the use of restrictive fluid therapy, specifically in the trauma patient, that increases systemic blood pressure without reaching normotension (normal blood pressures). The goal blood pressure for these patients is a mean arterial pressure of 40-50 mmHg or systolic blood pressure of ...
Alpha-blockers, like prazosin (Minipress®), are typically used to manage high blood pressure. These medications work by blocking the norepinephrine to help prevent blood vessels from tightening ...
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.
