errors in blood pressure (bp) measurement are common in the clinical practice. inaccurate measurements of bp may lead to misdiagnosis and inappropriate treatment of hypertension. the preferred method of bp measurement in the clinical setting is a scultation, using the first and the fi fth korotkoff sounds. however, the use of mercury sphygmomanometer is declining. automated oscillometric device...

we investigated the issue of noise pollution in the bidboland gas refineryby noise measurement and surveys. the bidboland gas refinery has several process units.the sound pressure levels were measured at several places, such as units of 200, 300,400, 500, boiler, powerhouse area, cooling towers pumps, and maintenance area, and thecorresponding noise maps were produced by using sound plan softwa...

The measurement of dynamic blood pressure has been of interest to physiologists and physicians since 1732, when Reverend Stephen Hales measured the blood pressure of a horse by using a vertical glass tube . Methodology has advanced impressively since Reverend Hales's day, but with increased technical capability has come greater complexity of instrumentation, so that few physicians today have a ...

PURPOSE To compare both home blood pressure measurement (HBPM) and ambulatory blood pressure monitoring (ABPM) with office blood pressure measurement (OBP); and also to compare the correlation between HBPM and OBP with LVMI (left ventricular mass index). METHODS Protocol 1--68 hypertensive patients (58 +/- 12 years, 37 females): a) self recorded blood pressure at home in the 7 days; b) record...

background: the most reliable indicator of vitamin d status is circulating concentration of 25‑hydroxycalciferol (25(oh) d) routinely determined by enzyme‑immunoassays (eia) methods. this study was performed to compare commonly used competitive protein‑binding assays (cpba)‑based eia with the gold standard, high‑pressure liquid chromatography (hplc). methods: concentrations of 25(oh) d in sera ...
