The Colorado Asthma Ski Day, an annual cross-country and alpine skiing event, encourages children with asthma to participate fully in outdoor winter sports. Since cold air and exercise can trigger bronchospasm, we examined the peak expiratory flow rates of 80 children who attended Asthma Ski Day 1992 or Asthma Ski Day 1993 to establish a safety profile for this event. Peak expiratory flow rates were measured prior to skiing, at lunchtime, and at the end of the day's activities. We asked the children to pretreat with their regular medications, as prescribed by their physicians, to use their bronchodilator inhalers p.r.n., and to report to our medical station if an episode of acute asthma occurred. The average age of the participants was 9.5 years, and the average baseline daytime peak flow rate was 100.03% of predicted. The average percent change in peak flow rates during the day was an increase of 5.00%. Our results demonstrate that with medical supervision, peak expiratory flow rate monitoring, and properly administered medications, peak flow rates can be stabilized and even improve during cold-weather exercise to an extent that safety concerns need not restrict children with asthma from engaging in exercise or cold-weather sports. The Colorado Asthma Ski Day can serve as a model event for other organizations that want to promote outdoor activities for children with asthma.
科罗拉多哮喘滑雪日是一项年度越野和高山滑雪活动，鼓励哮喘患儿充分参与户外冬季运动。由于冷空气和运动可能引发支气管痉挛，我们对参加1992年或1993年哮喘滑雪日的80名儿童的呼气峰值流速进行了检测，以确定该活动的安全状况。在滑雪前、午餐时间以及当天活动结束时测量呼气峰值流速。我们要求孩子们按照医生的处方使用常规药物进行预处理，必要时使用支气管扩张剂吸入器，并且如果发生急性哮喘发作要向我们的医疗站报告。参与者的平均年龄为9.5岁，平均基线日间峰值流速为预测值的100.03%。白天峰值流速的平均变化百分比为增加5.00%。我们的结果表明，在医疗监督、峰值流速监测以及正确用药的情况下，峰值流速可以保持稳定，甚至在寒冷天气运动期间有所提高，以至于安全问题无需限制哮喘患儿参与运动或寒冷天气运动。科罗拉多哮喘滑雪日可以为其他希望促进哮喘患儿户外活动的组织提供一个示范活动。
