Seventy asthmatic patients newly referred to a hospital outpatient clinic have been studied. In one-third of the patients the diagnosis of asthma had not been considered. Eight patients presented with an FEV1 of one litre or less. Acute severe asthma is commonly believed to precede death from asthma, but patients with more chronic symptoms may have equally severe airways obstruction without appearing acutely ill. Failure to diagnose and treat such patients may be contributing to our present inability to reduce the death rate from asthma.
对新转诊至一家医院门诊的70名哮喘患者进行了研究。三分之一的患者此前未被诊断为哮喘。8名患者的第一秒用力呼气量(FEV1)为1升或更低。一般认为急性重症哮喘是哮喘致死的先兆,但有更多慢性症状的患者可能存在同样严重的气道阻塞,却没有急性发病的表现。未能诊断和治疗这类患者可能是导致我们目前无法降低哮喘死亡率的原因之一。
