Summary: In 23 children with asthma and 18 healthy controls, cold air challenge (CACh) was done twice during the same half day, and in the asthmatics a third time together with a histamine challenge (HCh) 2 wk later. Pulmonary functions were tested before and after each challenge. No overlapping of individual responses to CACh in seven forced expiratory flow tests proved the power of discrimination of this technique in children. The limits of “normal” reactions ranged from minus 9% for larger… CONTINUE READING
