An asthmatic patient managed with albuterol (rescue inhaler) had their last asthma exacerbation 10 months ago and reports good overall control. What is the most appropriate ASA Physical Status classification?

A patient with a chronic but generally well-controlled systemic condition (here, asthma without a recent exacerbation, managed adequately with a rescue inhaler) fits ASA II — mild systemic disease without significant functional limitation. ASA I would be inappropriate since asthma is a genuine systemic disease (ruling out a 'completely healthy' classification), while ASA III/IV would apply to poorly controlled disease with frequent exacerbations or more severe functional impact.
