background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...

introduction blood pressure (bp) is one of the important vital signs that need to be monitored for personal healthcare. arterial blood pressure is estimated from pulse transit time (ptt). this study uses two pulse sensors to get ptt. the aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. materials and m...

conclusions our study could not show any correlation between sleep quality and ambulatory bp monitoring parameters in children with abnormal bp. objectives the aim of this study was to investigate the correlation between sleep quality parameters and blood pressure (bp) changes in children. patients and methods eighty six patients aged 5-15 years old with the history of urinary tract infection w...

Background: The virtual rise of blood pressure resulted from stress, that is observed in subjects that are tested in medical centers, can be oftenly corrected by holter. This phenomenon causes such persons not to response to the common anti blood pressure treatments (2). Materials and methods: This descriptive study was conducted 2006-2007 at the heart clinic of Shohadaye–Ashayer hospital in Kh...

abstract  introduction: hypertension is a very common cardiovascular disease with extensive effects on body organs. this study was conducted to compare the extent of target organ damage in hypertensive patients with and without significant nocturnal fall in blood pressure (dippers and non-dippers, respectively). methods: one-hundred patients with recently diagnosed hypertension underwent 24-hou...

Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...
