Fourteen asthmatic children, aged 7.9 to 18.0 years (mean, 11.3 years), recorded peak expiratory flow rates three times a day at home for four weeks in an attempt to improve perception of their airway obstruction. Pulmonary function tests were performed and a subjective severity score was recorded before and after this period. The accuracy of the parents' perceptions of their child's airway obstruction was also assessed. These children were unable to accurately predict their degree of airway obstruction, and no improvement in prediction was seen following the learning period. Parents' perceptions of the child's airway obstruction were also inaccurate. Recording of peak expiratory flow rate at home did not improve the child's perception of his asthma. Rational management of troublesome asthma requires the use of an inexpensive peak flowmeter to provide continual objective measurements of lung function.
14名年龄在7.9至18.0岁（平均11.3岁）的哮喘儿童在家中每天记录三次呼气峰值流速，持续四周，以提高他们对气道阻塞的感知。在此期间前后进行了肺功能测试并记录了主观严重程度评分。还评估了父母对其孩子气道阻塞感知的准确性。这些儿童无法准确预测其气道阻塞程度，在学习期后预测也未见改善。父母对孩子气道阻塞的感知同样不准确。在家中记录呼气峰值流速并未改善孩子对其哮喘的感知。对难治性哮喘的合理管理需要使用廉价的峰值流量计来持续客观地测量肺功能。
