Arterial blood gas data were correlated with clinical variables including patients' perception of dyspnea and spirometry in 79 episodes of acute asthma attacks. Among several variables that showed univariate significance with severity, only subjective degree of dyspnea rated on a modified Borg scale (MBS) remained predictive to discriminate the presence or absence of hypoxia/hypercapnia in multivariate analyses. MBS alone could predict the arterial blood gas status with accuracy of approximately 75%. Therefore, patients' sensation of dyspnea seemed to be an important factor in the evaluation of acute asthma in an emergency room.
在79次急性哮喘发作中，对动脉血气数据与包括患者呼吸困难感知和肺活量测定在内的临床变量进行了相关性分析。在几个与严重程度具有单变量显著性的变量中，在多变量分析中，只有采用改良博格量表（MBS）评定的主观呼吸困难程度仍然能够预测是否存在低氧血症/高碳酸血症。仅MBS就能以约75%的准确率预测动脉血气状态。因此，患者的呼吸困难感觉似乎是急诊室评估急性哮喘的一个重要因素。
