目的探讨简易气道反应性测定仪可靠性及应用价值。方法用广州产TAR-1型简易气道反应性测定仪、以乙酰甲胆碱为诱导剂对疑诊为职业性哮喘的10例病人进行了气道反应性测定,并与日本Chest Tck-6100H型气道反应性测定仪(Astograph法)测定结果进行比较。结果二种仪器测定的结果具有很好的一致性。结论说明TAR-1型简易气道反应性测定仪完全可以代替其他大型仪器用于职业性哮喘的诊断和流行病学调查。
Objective To study the reliability and application value of simple airway reactivity meter. Methods Airway reactivity was measured in 10 patients diagnosed as occupational asthma by using TAR-1-type simple airway reactivity meter in Guangzhou and methacholine as an inducer, and compared with Chest Tck-6100H Type airway reactivity analyzer (Astograph method) measured results were compared. Results The results of the two instruments were in good agreement. Conclusion TAR-1-type simple airway reactivity tester can replace other large instruments for the diagnosis and epidemiological investigation of occupational asthma.
