作者根据对慢性哮喘病人每天数次进行高峰呼气流率的观察,认为可分为下列类型: 1.脆性哮喘对所有常规治疗无效,一会儿哮鸣音全部消失,一会儿哮喘大发,常和情绪有关。24小时内气道阻塞情况不一,可自正常至严重阻塞,而且毫无规律,流率降低时吸入小剂量支气管扩张剂如O.2毫克索必它即能使其增加,但持续使用甚至和氨茶硷合用并不能防止或减轻哮喘发作,因此患者须经常使用支气管扩张气雾剂。 2.晨间发作型哮喘晨间高峰呼气流率最低,白天则稳定而且可以正常。因此下午检查时常误认为并无哮喘。夜间记录显示清晨2时左右流率最低。有的自午夜起逐渐降低,有的则突然降低,此类型可解释为何哮喘的死亡在晨间1时至8时最易发生。有些严
The authors, based on observations of peak-to-peak expiratory flow rates in patients with chronic asthma several times per day, concluded that they could be divided into the following categories: 1. Fragile asthma was ineffective for all routine treatments and wheeze disappeared for a while, with a brief episode of asthma, related. 24-hour airway obstruction varies, from normal to severe obstruction, and there is no law, the flow rate decreases when inhaled small doses of bronchodilators such as O.2 milligrams cable it will increase it, but continued to use or even In combination with ammonia theophylline does not prevent or reduce the onset of asthma, so patients should frequently use bronchodilators. Morning onset asthma Morning peak expiratory flow rate is the lowest during the day is stable and can be normal. Therefore, the afternoon check is often mistaken for asthma. Nighttime records showed the lowest flow rate around 2 am Some decreased gradually from midnight, while others decreased suddenly. This type of explanation may explain why the death of asthma is most likely to occur at 1 am to 8 am in the morning. Strict
