An alternate renewable energy source, through a piezoelectric vibration harvester with bluff splitter body, could lead to higher efficiency in harvesting, vortex-induced at near-resonance condition 20 m/s high wind speed. However, is not as popular solar energy, the main source Malaysia, due relatively low speed available country. The INVELOX machine, introduced 2014, was one of most recent sys...
BACKGROUND Aim of the study was to compare the short-term effects of oxygen therapy via a high-flow nasal cannula (HFNC) on functional and subjective respiratory parameters in patients with acute hypoxic respiratory failure in comparison to non-invasive ventilation (NIV) and standard treatment via a Venturi mask.
