Microbubble generation and transmission of medtronic's affinity hardshell venous reservoir and collapsible venous reservoir bag: an in-vitro comparison.
Microemboli are implicated in neurological injury; therefore, the extracorporeal circuit (ECC) should not generate microbubbles or transmit introduced air. The venous reservoir is the first component in the ECC designed to remove introduced air. The purpose of this study was to investigate the relative safety of two kinds of adult venous reservoirs--the closed soft-shell venous reservoir (SSVR ...
متن کاملAn In Vitro Comparison of Micro Air Passage in the Venous Reservoir Bag
_____________ _ The increasing use of membrane oxygenators and collapsable venous reservoir bags (VRB) imposes a concern not associated with bubble oxygenators: Venous line air. Since no defoamer is present, a VRB must rely on flow characteristics or a barrier to remove air from the venous return. The purpose of this study is to determine the air removal efficiency of seven commercially availab...
متن کاملThe efficacy of an oxygen mask with reservoir bag in patients with respiratory failure.
BACKGROUND Oxygen masks with reservoir bags (OMR) are widely used for oxygen therapy in patients with severe respiratory failure. The purpose of the present study was to determine whether OMRs are effectively used in clinical practice. METHODS AND RESULTS In the first phase of the study on the patients with severe respiratory failure, no apparent respiratory motions of the reservoir bag were ...
متن کاملThe Total Luminous Efficiency of Luminous Bacteria
Methods are described for measuring the light emitted by an emulsion of luminous bacteria of given thickness, and calculating the light emitted by a single bacterium, measuring 1.1 x 2.2 micra, provided there is no absorption of light in the emulsion. At the same time, the oxygen consumed by a single bacterium was measured by recording the time for the bacteria to use up .9 of the oxygen dissol...
متن کاملLuminous Phenomena of Earthquakes: Observations and Theories
Over the past few years, different theories (piezoelectric, positive holes, friction-vaporization, exo-electron emission, tribo- or fracture electrification) have been presented for the interpretation of earthquake lights. Although these theories can interpret earthquake luminous, each suffer from particular problems. There are also ambiguities and questions about the location of the light, the...
