It is again important that the blood pressure is lowered slowly. The initial goal in hypertensive emergencies is to reduce the pressure by no more than 25% the mean arterial pressure. Excessive reduction in blood pressure can precipitate coronary, cerebral, or kidney ischemia and, possibly, infarction. [citation needed]
Sometimes it can be an acute problem, such as in a hypertensive emergency when blood pressure is more than 180/120 mmHg. [49] Levels of arterial pressure put mechanical stress on the arterial walls. Higher pressures increase heart workload and progression of unhealthy tissue growth that develops within the walls of arteries.
A stone from the Master Pit had been dated to over 200,000 BP. This date could have been the result of contamination from other elements in the soil, so currently there is an effort to date verified lithics through thermoluminescence dating. While the results are still pending, the styles suggest 20,000 to 30,000 BP.
The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. [5] [6] This usage differs from the recommendation by van der Plicht & Hogg, [7] followed by the Quaternary Science Reviews, [8] [9] both of which requested that publications should use the unit "a" (for "annum", Latin for "year") and reserve the term "BP" for radiocarbon estimations.

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 ...
The stock now trades at a more than 55 times forward price-to-earnings (P/E) ratio. However, questions surrounding Costco's valuation have been a pretty common theme during the past few years, and ...
The oldest archaeological records ever discovered in the municipality of São Paulo were collected at the Morumbi site, [6] presenting an estimated dating of 5 500 years BP. [7] Found by chance in 1964, more than 200 000 stone tools were identified at the Morumbi site over four stages of excavation, which would reinforce the hypothesis that it ...
