呼气峰流速(peak expiratory flow, PEF)是指用力呼气的最高流量,能够反应气道的通畅性,是通气功能的常用检查之一,广泛应用于哮喘病人的自我监测。PEF与 FEV1有很好的相关性,尽管PEF的重复性低于FEV1,但PEF较FEV1更易获得。 经过广泛阅读既有研究文献,并进行初步预实验筛选后,本研究选取呼气峰流速作为实验对象,观察其...
In this regard, there are some recent initiatives to try to improve lung function evaluation in primary care medicine with different devices beyond formal spirometry such as the Piko-6,24 the COPD-6,25 micro- spirometry26 and the peak-flow meter.27 Additionally, several questionnaires have also...
Peak Expiratory Flow MMEF: Maximal Mid-Expiratory Flow HDL-C: High-density lipoprotein cholesterol LDL-C: Low-density lipoprotein cholesterol TG: Triglycerides WBCs: White blood cells PLTs: Platelets HGB: Hemoglobin GLU: Blood glucose Cr: Serum creatinine Alb: Serum albumin ALT: ...
This threshold was selected to account for when the extraction software may have missed a peak, thus resulting in one replicate having low to no signal and therefore causing a larger CV across replicates. The data was then filtered for compounds that were found in at least 80 percent of ...
Of these symptoms, dyspnoea (measured by peak VO2).8 is partly relieved in 50%, but low mood is relieved in only 8% These are not measures easily obtained in family or general of cases and not treated in 82%.3 Murray has identified the practice, although they are useful if they are...

However, in a study of adults and adolescents with asthma, BFC pMDI and BFC Turbuhaler significantly (P , 0.001 for both) improved AM peak expi- ratory flow (PEF; the primary efficacy variable) compared with budesonide pMDI.34 In a 52-week long-term safety study of patients with ...
IRV. After this point, further increases in\( \dot{\mathrm{V}} \)E are accomplished by acceleratingFb. Data plotted are mean values at steady-state rest, isotime (i.e., 2 min, 4 min), the VT//\( \dot{\mathrm{V}} \)E inflection point and peak exercise. (Modified from: [29...
(h) Bar chart showing averaged value of iron intensity in healthy donors and COPD (GOLD IV) patients’ lung tissue. The error bars show 95% confidence level for each peak in 3 tissue sections per group with 5 random areas per tissue. ***p<0.001, using student’s t-test. Full size ...
11. While teaching a patient with asthma the appropriate use of a peak flow meter, the nurse instructs the patient to a. take and record peak flow readings when having asthma symptoms or an attack. b. increase the doses of long-term control medications for peak flows in the red zone. ...
