Physiologically acceptable limits of inspiratory impediment for air purifying respirators (APRs) were sought. Measurements on 30 subjects included pressure in, and flow through, an APR, and respiratory and cardiovascular variables. Exercise with and without APR included ladder climbing, load lift an...
