| Abstract: | Studied the influence of actual and false peak flow (PEF) informationon dyspnea (breathlessness) in two experiments, each with 30children with and 30 without asthma (717 years). Dyspnea,PEF, and lung function were measured before and after standardizedphysical exercise. Dyspnea was measured with a visual analogscale. PEF was measured with a peak flow meter and used formanipulation of dyspnea. The first experiment showed that therelationship between dyspnea and lung function was not strongerwhen children had knowledge of PEF values. The second experimentrevealed that asthmatic children who received false feedbackof 30% below the actual PEF reported significantly more dyspnea.Implications for the management of asthma are discussed. |
