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 ...
Orthostatic hypotension, also known as postural hypotension, [2] is a medical condition wherein a person's blood pressure drops when they are standing up (orthostasis) or sitting down. Primary orthostatic hypotension is also often referred to as neurogenic orthostatic hypotension. [ 3 ]
Blood pressure measurements can be influenced by circumstances of measurement. [10] Guidelines use different thresholds for office (also known as clinic), home (when the person measures their own blood pressure at home), and ambulatory blood pressure (using an automated device over a 24-hour period).
Hypovolemia can be recognized by a fast heart rate, low blood pressure, [12] and the absence of perfusion as assessed by skin signs (skin turning pale) and/or capillary refill on forehead, lips and nail beds. The patient may feel dizzy, faint, nauseated, or very thirsty. These signs are also characteristic of most types of shock. [13]
Vasoconstriction is a procedure of the body that averts orthostatic hypotension. It is part of a body negative feedback loop in which the body tries to restore homeostasis (maintain constant internal environment). [citation needed]
Autonomic dysfunction may be present and can manifest as hypotension (either orthostatic or frank hypotension), sexual dysfunction, and/or bowel and bladder dysfunction [4] [5] Areflexia, flaccid internal and external anal sphincter, urinary retention and intestinal obstruction may also be present in individuals with anterior cord syndrome. [1]
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system.Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1]
