对93例哮喘患者320例次进行了喘息和最大呼气流速(PEFR)检查。出现喘息(患者报告或检查时发现)与PEFR显著降低有关。呼气性喘息通常伴有吸气性喘息；这种双相喘息与PEFR低于单纯呼气性喘息有关。喘息的响度和高音与更严重的梗阻有关。大多数呼气喘息持续整个呼气。呼气或吸气时的呼气或吸气时的呼气或吸气时的虽然喘息的特征与呼吸道阻塞的严重程度有一般关系，但客观地测量呼气流速对于评估每个患者的病情是必要的。
Ninety-three asthmatic patients were examined on 320 occasions for wheezing and peak expiratory flow rate (PEFR). The presence of a wheeze (either reported by the patient or found on examination) was associated with a significantly lower PEFR. Expiratory wheezing was usually accompanied by inspiratory wheezing; this biphasic wheezing was associated with a lower PEFR than only expiratory wheezing. Loudness and the high pitch of wheezing were associated with more severe obstruction. Most expiratory wheezing lasted throughout the entire expiration. Expiratory or inspiratory wheezing of high pitch, moderate to severe intensity, and spanning the entire phase of the breath was associated with a lower PEFR than wheezing without these characteristics. Although characterization of wheezing has a general relationship to the severity of airway obstruction, an objective measurement of expiratory flow rate is necessary for the evaluation of each patient's condition.
