Treatment effect of furosemide (blackbars) and saline (shaded bars) in the seven subjects who provided high quality data for aerosol furosemide treatment. Bars indicate the change in Breathing Discomfort at benchmark PETCO2 following 80 mg furosemide aerosol or an equal volume of saline. Crosshatched bars indicate mean ±SE. AF68, AF71, AF73, AF85, & AF94 contributed no data that survived stringent quality control.
