您要查找的是不是：
- forced expiratory flow rate volume interval 在肺活量某容量段用力呼气的流速
- forced expiratory flow rate 用力呼气流速
- Forced expiratory volume at 1st s (FEV1.0), forced volume capacity (FVC), FEV1.0/ FVC and peak expiratory flow (PEF) were measured preoperatively and then daily after surgery. 术前及术后每日测定用力肺活量 (FVC) ,第一秒用力呼气量 (FEV1 0 ) ,第一秒用力呼气量占用力肺活量的百分率 (FEV1 0 FVC)及呼气流量峰值(PEF)。
- Acute iloprost inhalation reduced forced expiratory volume in 1 s and mid-volume forced expiratory flow by 5% and 10%, respectively, consistent with acute bronchoconstriction. 急性伊洛前列素吸入分别降低1秒用力呼气量和呼气中段流速5%25和10%25，与急性支气管收缩一致。
- Peak expiratory flow rate(PEFR) after treatment for 12 months was higher than that after treatment for 6 months and before treament. 最大呼气峰速值(PEFR)在治疗12个月后较治疗6个月及治疗前明显增加。
- Objective:To observe the applied value of peak expiratory flow rate(PEFR) simple testing(test PEFR at 8 Am and 8 Pm daily) in the moderate to severe asthma. 目的:观察呼气峰流速简易测定法在中重度哮喘治疗中的应用价值。
- As compared with the control group, the improvement of the average peak expiratory flow (PEF) in the morning, the forced expiratory volume in 1 second (FEV1) and no-symptom days significantly increased in the test group (P <0.05). 试验组患者平均晨间最大呼气流量(PEF)的改善和一秒钟用力呼气量(FEV1)及无症状天数的增加较对照组明显(P<0.;05)。
- After treatment, the forced expiratory volume in 1 second was increased in the treatment group (P<0.05), and the peak expiratory flow was accelerated in the control group (P<0.05). 治疗组治疗后1秒钟用力呼气容积增大(P<0.;05)，对照组治疗后呼气峰流速加快(P<0
- forced expiratory flow during middle half of FVC 用力呼气中段流量
- determination of maximal expiratory flow rate 最大呼气流率测定
- BACKGROUND: In some subjects with suspected asthma who have normal spirometry, administration of bronchodilators (BD) improves expiratory flow rates. 背景： 对于肺活量正常的可疑哮喘患者，给予支气管扩张剂（BD）能改善呼气流速。
- Peak expiratory flow rate through the nose; PEFRn 经鼻最大呼气流速
- Normal peak expiratory flow rate 正常呼气流量率峰值
- forced expiratory flow between 25 and 75% of forced vital capacity 25-75%25间强迫肺活量时用力呼气量
- Expiratory flow rate measurement 呼气流量率测量
- Decreased peak expiratory flow rate 呼气流量率峰值减少
- Increased peak expiratory flow rate 呼气流量率峰值增加
- maximal expiratory flow rate, MEFR 最大呼气流速
- peak expiratory flow rate through the nose 经鼻最大呼气流速, 经鼻峰值呼气流速
- forced expiratory flow after 25% of vital capacity has been expelled 排出25%25肺活量后用力呼气量
