Background and Objectives: Suction is a necessary and common method which aids in the release of secretion from the respiratory system for the patients who have undergone mechanical ventilation. One of the most common complications of suction is hypoxemia which causes dysrhythmia and death. The purpose of this study was to determine the effects of open and closed-endotracheal suction on cardiov...

BACKGROUND An earlier randomized, controlled trial showed that weekly or as-needed (as opposed to daily) changes of in-line suction catheters were associated with substantial cost savings, without a higher rate of ventilator-associated pneumonia (VAP). To examine the impact of decreasing the frequency of in-line suction catheter changes in our medical intensive care unit, we conducted an observ...

in this study, the effect of suction and the parameters such as suction amplitude, suction coefficient and suction jet length on naca0012 was evaluated. the turbulence employed model was the rsm model. suction jet is located in 10% of the chord length. the range of suction jet entrance velocity was selected from 0.1 to 0.5 of freestream velocity. the maximum increase in lift to drag ratio was s...

Permeability and air flow rate in the bed during iron ore sintering is crucial to control sinter quality productivity, due its influence on flame front speed. In present work, permeability of an blend was analysed utilising simultaneously measured pressure temperature at multiple points bed. Three different zones were categorized, i.e., humidified (green) bed, region maximum resistance (high-te...

In this paper, the transient refrigerant gas flow in a two-cylinder rolling piston type rotary compressor is simulated using STAR-CD, a general computational fluid dynamics (CFD) software. Three models with different suction piping systems are calculated respectively, one is two suction pipes were connected from accumulator to each cylinder separately (separate suction piping system), the other...

a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...

The compression efficiency of a rolling piston type rotary compressor for room airconditioners was analyzed, Suction passage loss is one of the detracting factors in compression efficiency and we studied its main cause, i.e. the pressure pulsation generated in the suction line, and clarified the relation between suction line specification and suction passage loss. A method of evaluating the suc...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...

Despite having almost identical origins and similar perfusion pressures, the flow-velocity waveforms in the left and right coronary arteries are strikingly different. We hypothesized that pressure differences originating from the distal (microcirculatory) bed would account for the differences in the flow-velocity waveform. We used wave intensity analysis to separate and quantify proximal- and d...
