| 1. | Mmfr forced expiratory flow during middle half of the fvc
最大呼气中期流速 |
| 2. | Fev1 forced expiratory volume in the first second
第1秒用力呼气量 |
| 3. | In addition , red tide exposure was associated with significant reductions in fe1 , midexpiratory phase of forced expiratory flow , and peak expiratory flow
另外，暴露于红潮会引起fe1 ? ?强迫呼气流量中值和呼气气流峰值减少。 |
| 4. | The researchers used forced expiratory volume in 1 second ( fev1 ) and forced vital capacity ( fvc ) as a percentage of predicted value ( fvcpp ) as indicators of lung function
研究者用用力第一秒呼气量( fev1 )和用力肺活量( fvc )和其预期值的百分比( fvcpp )作为肺功能衡量指标。 |
| 5. | Other outcomes included the forced expiratory volume in one second ( fev1 ) before and after bronchodilator treatment , the frequency of exacerbations , the degree of asthma control , the number of symptom - free days , and the quality of life
其他转归包括支气管扩张剂治疗前后的一秒钟用力呼气容积( fev1 ) 、急性加重频率、哮喘控制程度、无症状天数和生活质量。 |
| 6. | The authors compared longitudinal measurements of forced expiratory flows by the raised volume rapid thoracic compression technique in the first and the second years of life for 26 healthy infants born prematurely vs 24 infants born at full term
作者比较了26个健康的早产儿和24个足月的婴儿的纵向测量力呼气流量，分别在他们一岁和两岁的时候，通过快速胸加压法产生的体积来进行测定。 |
| 7. | The preterm group continued to have decreased forced expiratory flows and normal forced vital capacities in the first and second years of life compared with the full - term group , even though their increases in lung function with growth were similar to those of full - term infants
尽管早产组的婴儿随着生长，肺功能的增强与足月组的婴儿相似，但在第一和第二周岁的时候，早产组和足月组的婴儿相比用力呼气流量和正常的肺活量持续减少。 |
| 8. | Several subclassifications have been proposed : simple chronic bronchitis describes a condition characterized by mucoid sputum production ; chronic mucopurulent bronchitis is characterized by persistent or recurrent purulence of sputum in the absence of localized suppurative diseases such as bronchiectasis ; chronic bronchitis with obstruction deserves a separate classification characterized by presence of airway obstruction as assessed by the used of the forced expiratory vital capacity maneuver ; and chronic asthmatic bronchitis
它可以分为以下几种类型：单纯性慢性支气管炎，其特征为咳粘液性痰；慢性粘液脓性支气管炎，其特征是反复的或持续的咳脓痰，但肺部并无化脓性病变，如支气管扩张；慢性支气管炎伴阻塞，其特征为用力呼气肺活量测定时有气道阻塞的表现；慢性哮喘性支气管炎，其特征是患者有长期的咳嗽及咯痰史，后来肺部出现哮鸣者，因此与哮喘伴慢性气管阻塞的病人不同。 |
