The speed at which air is drawn into a fume hood is of great importance for the safe and effective operation of a fume hood. A speed that is too high or too low can compromise the performance of the fume hood, leaving those near the hood in danger. So why does this airspeed matter? What is so significant about the face velocity measurement of a fume hood? What is a Fume Hood Face? If we are going ...
Exhaled air dispersion distances during noninvasive ventilation via different Respironics face masks
Abstract Background: As part of our influenza pandemic preparedness, we studied the exhaled air dispersion distances and directions through two different face masks (Respironics; Murrysville, ...
