  2. Orthostatic hypotension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypotension

    The drop in blood pressure may be sudden (vasovagal orthostatic hypotension), within 3 minutes (classic orthostatic hypotension) or gradual (delayed orthostatic hypotension). [4] It is defined as a fall in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least

  3. Orthostatic hypertension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypertension

    Some specialists in severe cases give saline intravenously for hypovolemia, which, if it is the cause, brings the orthostatic hypertension down to a safe level. Pressure garments over the pelvis and the lower extremities may be used as part of treatment, due to the blood pooling issue occurring in many with the disorder. [12]

  4. Management of hypertension - Wikipedia

    en.wikipedia.org/wiki/Management_of_hypertension

    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. [4]

  5. Blood pressure - Wikipedia

    en.wikipedia.org/wiki/Blood_pressure

    The difference between the systolic and diastolic pressures is known as pulse pressure, [1] while the average pressure during a cardiac cycle is known as mean arterial pressure. [2] Blood pressure is one of the vital signs—together with respiratory rate, heart rate, oxygen saturation, and body temperature—that healthcare professionals use ...

  6. Hypertension - Wikipedia

    en.wikipedia.org/wiki/Hypertension

    Multiple blood pressure readings (at least two) spaced 1–2 minutes apart should be obtained to ensure accuracy. [92] Ambulatory blood pressure monitoring over 12 to 24 hours is the most accurate method to confirm the diagnosis. [93] An exception to this is those with very high blood pressure readings, especially when there is poor organ ...

  7. Edema - Wikipedia

    en.wikipedia.org/wiki/Edema

    Hydrostatic pressure within blood vessels tends to cause water to filter out into the tissue. This leads to a difference in protein concentration between blood plasma and tissue. As a result, the colloidal or oncotic pressure of the higher level of protein in the plasma tends to draw water back into the blood vessels from the tissue.

  8. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles. [35] Gravity affects blood pressure via hydrostatic forces (e.g., during standing), and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins. [32]

  9. Essential hypertension - Wikipedia

    en.wikipedia.org/wiki/Essential_hypertension

    Blood pressure is classified as normal blood pressure, prehypertension, hypertension (stages I and II), and isolated systolic hypertension, which is a common occurrence among the elderly. These readings are based on the average of seated blood pressure readings that were properly measured during 2 or more office visits.
