Novel Radon Sub-Slab Suctioning System
A new principle for radon protection is currently presented which makes use of a system of horizontal pressurised air ducts located within the lower part of the rigid insulation layer of the ground-floor slab. The function of this system is based on the principles of pressure reduction within the zone below the ground-floor construction. For this purpose a new system of prefabricated lightweigh...
متن کاملModeling of the Sub-slab Depressurization (ssd) Radon Mitigation Systems for Large Structures
There are several Active Soil Depressurization (ASD) computer based models that have been specifically designed and calibrated for residential structure ASD system applications and mitigation practices. Large structures encountered in large buildings are significantly different than residential structures and consequently different treatments are required. Considerations for substantially large...
متن کاملA novel visual sputum suctioning system is useful for endotracheal suctioning in a dog model.
OBJECTIVE This study is to test the effectiveness of fiber-optic-guided endotracheal suction catheter (visual sputum suctioning system or VSSS) in dog models. METHODS Dog sputum models were established by administering dimethoate emulsifiable. Twenty-seven intubated dogs were equally randomized into three groups of conventional suctioning (CS) group, VSSS with no supplemental oxygen (VSSS) gr...
متن کاملSub - Slab Depressurization Demonstration in Polk County
Six slab-on-grade houses in Polk County, Florida, with indoor radon levels between 19 and 80 pCi/1 were mitigated using sub-slab depressurization systems. With the compacted, moist soil fill under the slabs, sufficient sub-slab communications were difficult to establish. Increasing the suction pit size and using more powerful fans improved the strength of the pressure fields within 3 to 8 m of ...
متن کاملTracheal tube biofilm removal through a novel closed-suctioning system: an experimental study.
BACKGROUND Tracheal tube biofilm develops during mechanical ventilation. We compared a novel closed-suctioning system vs standard closed-suctioning system in the prevention of tracheal tube biofilm. METHODS Eighteen pigs, on mechanical ventilation for 76 h, with P. aeruginosa pneumonia were randomized to be tracheally suctioned via the KIMVENT* closed-suctioning system (control group) or a no...
