PRIMARY outcome

Timeframe: 0 to 60 minutes

Population: Healthy volunteers, median age 32 years. The population is 24 individuals they are randomized to which bronchodilator they received first. Half were randomized to Albuterol and half to levalbuterol but each subject received both medication. It is a matter of which they received first. There was a four hour wash out period between the first and second medication.

Oxygen consumption will be measured following for up to 60 minutes beta agonist aerosol
