Ergonomic Design and Evaluation of a Pilot Oxygen Mask
The present study developed a virtual fit assessment (VFA) method to design an oxygen mask which fits Korean Air Force (KAF) pilots. The VFA method used 3D face scan data of 336 KAF pilots to find the most proper shape of an oxygen mask for KAF pilots. The oxygen mask design revised in the study showed a 27% design improvement effect on average in terms of fit evaluated by the VFA method. Addit...
متن کاملErgonomic Evaluation of Manufacturing System Designs
Using high-level, 3-D computer graphics simulation and other engineering analysis tools, this research investigates the ergonomic advantages of one manufacturing system design over another. The designs compared are lean manufacturing (manufacturing cells) and the functional (job shop) design. Simulation models based on an actual manufacturing cell and its workers are used to generate correspond...
متن کاملAn ergonomic evaluation of excavating operations: a pilot study.
Previous studies indicate that oper ators of heavy construction equipment are aff icted by musculoskeletal injuries of the arms, shoulders, neck, and lower back. These injuries appear to be due to excessive periods of sitting (static posture), work intensity, whole-body vi bration, high resistance levers, repetitive motions, and awkward postures.2 5) Al though numerous studies have shown an ...
متن کاملThe clinical evaluation of the Respi-check mask: a new oxygen mask incorporating a breathing indicator.
UNLABELLED Study objective-To investigate the correlation between the Respi-check sensor and simultaneous chest auscultation in determining the respiratory rates in adults. METHODS Random visits to a local accident and emergency (A&E) department were made and all patients wearing oxygen masks were recruited into the study. The new sensor was attached to the outside of the mask. One researcher...
متن کاملComparison of the OxyMask and Venturi mask in the delivery of supplemental oxygen: pilot study in oxygen-dependent patients.
BACKGROUND The OxyMask (Southmedic Inc, Canada) is a new face mask for oxygen delivery that uses a small 'diffuser' to concentrate and direct oxygen toward the mouth and nose. The authors hypothesized that this unique design would enable the OxyMask to deliver oxygen more efficiently than a Venturi mask (Hudson RCI, USA) in patients with chronic hypoxemia. METHODS Oxygen-dependent patients wi...
