OBJECTIVES The decision to proceed to simple underwater seal drainage or to apply active suction to the underwater seal following pulmonary operation is a controversial one. For the sake of selecting the alternative to reduce postoperative air leakage, we performed a meta-analysis of randomised controlled trials (RCTs) to determine the benefit of suction or non-suction following lung surgery on...

Most aquatic vertebrates use suction to capture food, relying on rapid expansion of the mouth cavity to accelerate water and food into the mouth. In ray-finned fishes, mouth expansion is both fast and forceful, and therefore requires considerable power. However, the cranial muscles of these fishes are relatively small and may not be able to produce enough power for suction expansion. The axial ...

BACKGROUND The purpose of this study is to evaluate the use of Tono-Pen XL in measuring IOP during the application of a suction ring in rabbit eyes with manometrically controlled IOP. METHODS Tono-Pen XL was calibrated against direct manometry in 10 rabbit eyes. A suction ring was then applied in 4 rabbit eyes and the IOP was determined manometrically during suction ring application at 350 mm...

Keywords: Flow around a circular cylinder Vortex-induced vibration Flow control Steady suction Mitigation of vortex-induced vibration a b s t r a c t In the present study, a flow control method is employed to mitigate vortex-induced vibration (VIV) of a circular cylinder by using a suction flow method. The VIV of a circular cylinder was first reproduced in a wind tunnel by using a spring–mass s...

background: endotracheal suctioning (ets) is one of the most common supportive measures in intensive care units (icu). ets may be associated with complications including hypoxia and tachycardia. closed system suctioning (css) decreases the rate of cardiorespiratory complication mainly due to continuation of ventilatory support and oxygenation during procedure. css has questionable efficacy, the...

Research on suction-feeding performance has mostly focused on measuring individual underlying components such as suction pressure, flow velocity, ram or the effects of suction-induced forces on prey movement during feeding. Although this body of work has advanced our understanding of aquatic feeding, no consensus has yet emerged on how to combine all of these variables to predict prey-capture p...
