[Blood pressure profile in patients with hyper- and hypotension: effect of physiological stresses]
Abstract:
Responses to physiological stresses, relationship between character and severity of these reactions and parameters of 24-hour blood pressure (BP) profile were studied in patients with arterial hyper- and hypotension. Disturbed regulation of BP in hyper-, and hypotension was associated not only with pronounced spontaneous BP variability but also with hyper- and hypotensive responses of BP to natural and modeled orthostatic, psychoemotional, physical and nutritional stresses. Frequency of hypotensive episodes in patients with hypertension was similar to that of hypertensive episodes in patients with hypotension. The use of stress tests facilitated assessment of BP responses to various loads, determination of clinical value of hemodynamic changes and possibilities of correction of detected disturbances.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Factors affecting Blood pressure
Physiological Factors:
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
