临床上可见女性月经期间易患呼吸道疾病,文献报告有月经性哮喘、月经性自发性气胸、月经性周期性咯血。为探讨月经周期和肺通气功能的关系,我们用广州医疗器械研究所研制的GD型微型最高呼气流速(PEF)仪测定200名健康女性月经期前、月经期、月经期后PEF的改变,了解女性月经周期肺通气功能的变化,并进一步探索预防治疗方法。 Clinically, women are susceptible to respiratory diseases during menstruation, the literature reports of menstrual asthma, menstrual spontaneous pneumothorax, menstrual periodic hemoptysis. To investigate the relationship between menstrual cycle and pulmonary ventilation, we measured the change of PEF after menstrual period, menstrual period and menstrual period in 200 healthy women using the GD-type micro-maximum expiratory flow (PEF) instrument developed by Guangzhou Institute of Medical Devices, To understand the female menstrual cycle, pulmonary ventilation function changes, and to further explore the prevention and treatment methods.
