SECONDARY outcome

Timeframe: 30 minutes

Population: Safety population

Improvement in FEV1 was defined as an increase of at least 12% compared with baseline (pre-first stimulation). The 30 minute measure was taken immediately after the second stimulation. (FEV1 measured as a percentage of normal, where greater that 80% is normal and less than 40% is severe degree of obstruction.)

SECONDARY outcome

Timeframe: 30 minutes

Population: Safety population

Improvement in dyspnea was defined as at least 1.5 point decrease on a 10 point Visual Analogue Scale (VAS) compared with baseline (pre-first stimulation). Where 0 = no dyspnea and 10 = very severe dyspnea. The 30 minute measure was taken immediately after the second stimulation.
