Two guidelines met the quality threshold of > 60% in at least five domains, qualifying as 'high' AAO-HNS and National Institute for Health and Care Excellence. Average ICC across all six domains was 0.87, suggesting near total agreement between reviewers. Ménière's disease remains a challenging entity to diagnose and treat; few existing clinical guidelines meet the standards of quality established by the AGREE II appraisal instrument.

The COVID-19 pandemic has caused a global mechanical ventilator shortage for treatment of severe acute respiratory failure. Development of novel breathing devices has been proposed as a low cost, rapid solution when full-featured ventilators are unavailable. Here we report the design, bench testing and preclinical results for an 'Automated Bag Breathing Unit' (ABBU). Output parameters were validated with mechanical test lungs followed by animal model testing. The ABBU design uses a programmable motor-driven wheel assembled for adult resuscitation bag-valve compression. ABBU can control tidal volume (200-800ml), respiratory rate (10-40bpm), inspiratory time (0.5-1.5s), assist pressure sensing (-1 to -20cm H O), manual PEEP valve (0-20cm H O). All set values are displayed on an LCD screen. Bench testing with lung simulators (Michigan 1600, SmartLung 2000) yielded consistent tidal volume delivery at compliances of 20, 40 and 70 (mL/cm H O). The delivered fraction of inspired oxygen (FiO ) decreased with y failure. ABBU provides oxygenation and ventilation across a range of parameter settings that may potentially provide a low-cost solution to ventilator shortages. A clinical
