A "cannot-ventilate, cannot-intubate" situation is critical. In difficult airway management, transtracheal jet ventilation (TTJV) has been recommended as an invasive procedure, but specialized equipment is required. However, the influence of upper airway resistance (UAR) during TTJV has not been clarified. The aim of this study was to compare TTJV using a manual jet ventilator (MJV) and the oxy...

venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...

This paper proposes a technique for measurement of liquid flow using venturi and ultrasonic flow meter(UFM) to have following objectives a) to design a multi-sensor data fusion (MSDF) architecture for using both the sensors, b) improve sensitivity and linearity of venturi and ultrasonic flow meter and c) detect and diagnosis of faults in sensor if any. Fuzzy logic algorithm is used to fuse outp...

Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as an important pathogen. Successful detection starts with the selection of an appropriate specimen collection device. The Copan ESwab, a new swab, was compared with a commonly used Copan Venturi swab for the recovery of MRSA. In vitro assessment was performed according to the Clinical and Laboratory Standards Institute (CLSI) M40-A...

The necessity for dissolved oxygen in water is crucial the survival and growth of aquatic organisms, particularly tilapia. Seventy-five percent tilapia will die if there insufficient water. This work seeks to develop a venturi bubble-generating technique combat scarcity A floating pump with capacity 12 m<sup>3</sup>/hour was selected as medium distributing generating vacuum pressure...
