Hypotension

32: 832:(MAP) measured using an arterial catheter or by continuous, non-invasive hemodynamic monitoring which measures intra-operative blood pressure beat-by-beat throughout surgery. A MAP <65 mmHg is considered hypotension. Intra-operative hypotension <65 mmHg can lead to an increased risk of acute kidney injury, myocardial injury or post-operative stroke. While an incidental finding of hypotension during a routine blood pressure measurement may not be particularly worrying, a substantial drop in blood pressure following standing, exercise or eating can be associated with symptoms and may have implications for future health. A drop in blood pressure after standing, termed postural or orthostatic hypotension, is defined as a decrease in supine-to-standing BP >20 mm Hg systolic or >10 mm Hg diastolic within 3 minutes of standing. Orthostatic hypotension is associated with increased risk of future cardiovascular events and mortality. 4686: 819:
is at or below 120/80 mmHg. If the systolic blood pressure is <90 mmHg or the diastolic blood pressure is <60 mmHg, it would be classified as hypotension. However, occasional blood pressure readings below 90/60 mmHg are not infrequent in the general population, and, in the absence of some

It is usually transient and represents a delay in the normal compensatory ability of the autonomic nervous system. It is commonly seen in 317:
For many people, low blood pressure goes unnoticed. For some people, low blood pressure may be a sign of an underlying health condition, especially when it drops suddenly or occurs with symptoms. Older adults also have a higher risk of symptoms of low blood pressure, such as falls, fainting, or

The vast and rapid compensation abilities of the autonomic nervous system allow normal individuals to maintain an acceptable blood pressure over a wide range of activities and in many disease states. Even small alterations in these networks can lead to hypotension. 31: 651:, can have this side effect. Simple blood pressure and heart rate measurements while lying, seated, and standing (with a two-minute delay in between each position change) can confirm the presence of orthostatic hypotension. Taking these measurements is known as 2369:
