Asthma is a chronic lung disease characterized by inflammation and narrowing of the airways, while aspiration is the inhalation of foreign material into the lungs. Asphyxia is a condition where there is a lack of oxygen and excess of carbon dioxide in the body. None of these conditions specifically refer to imperfect dilation of the lungs.
