24 Hour ambulatory blood pressure monitoring (ABPM) was performed to provide data on the normal daily blood pressure of healthy schoolchildren and on patients with hypertension. The subjects studied were 123 healthy schoolchildren with a mean (SD) age of 12.5 (1.6) years (range 9.5-14.5 years), 24 children with borderline or mild hypertension, 17 with renal hypertension and normal renal functio...

BACKGROUND Cyclic redistribution of air within the cuff during respiratory pressure changes creates a self-sealing mechanism which allows tracheal sealing, despite tracheal airway pressure being above baseline cuff inflation pressure. The aim of the present study was to investigate the effect of continuous automated cuff pressure regulation on tracheal sealing during cyclic respiratory pressure...

With abundance of water on the earth the fresh water sources are limited. So a need arises to precisely measure this resource in many industrial and commercial places wirelessly. Many measurement techniques for liquid such as float, pressure gauge, ultrasonic and radar are available. Floats and pressure gauge suffer from cumulative error which increases with time whereas ultrasonic and radar gi...

Vertical flow systems (VFS) are a type of passive treatment unit process in which acid mine drainage (AMD) flows vertically through layers of organic matter and limestone. Located in the coal belt of eastern Oklahoma, the Red Oak VFS was constructed to address AMD exiting an abandoned underground coal mine. The passive treatment system consists of five cells, alternating between surface flow (c...

Research conducted by Muhaji, Bedjo Santoso, Putrono on the comparison of effectiveness two levels suction pressure oxygen saturation in endotracheal tube patients. The findings show that there is a significant effect negative saturation. So use value must be ensured it appropriate so as not to injure patient. accuracy and can calibrating pump with calibrator, namely Digital Pressure Meter. Fro...
