Abstract Background This study seeks to compare the ability of repeatable invasive and noninvasive lung function methods to assess allergen-specific and cholinergic airway responsiveness AR in intact spontaneously breathing BALB c mice. Methods Using noninvasive head-out body plethysmography and the decrease in tidal midexpiratory flow EF50 we determined early AR EAR to inhaled Aspergillus fumigatus antigens in conscious mice. .
