Peak expiratory flow rate as a surrogate for forced expiratory volume in 1 second in COPD severity classification in Thailand
BACKGROUND There are limited studies directly comparing correlation and agreement between peak expiratory flow rate (PEFR) and forced expiratory volume in 1 second (FEV1) for severity classification of COPD. However, clarifying the role of PEFR as a surrogate of COPD severity classification instead of FEV1 is essential in situations and areas where spirometry is not routinely available. PURPO...
متن کاملPeak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
متن کاملPeak flow rate in relation to forced expiratory volume in hemp workers.
v Zuskin, E., and Vali, F. (1971). Brit. J. industr. Med., 28, 159-163. Peak flow rate in relation to forced expiratory volume in hemp workers. Measurements of the forced expiratory volume in one second (FEV1.0) and the peak expiratory flow rate (PEF) were made in 99 non-smoking female hemp workers before and after the shift. A significant mean reduction of both FEV1.o and PEF (P < 0-01) over t...
متن کاملChanges in forced expiratory volume in 1 second over time in COPD.
BACKGROUND A key feature of chronic obstructive pulmonary disease (COPD) is an accelerated rate of decline in forced expiratory volume in 1 second (FEV(1)), but data on the variability and determinants of this change in patients who have established disease are scarce. METHODS We analyzed the changes in FEV(1) after administration of a bronchodilator over a 3-year period in 2163 patients. A r...
متن کاملNormal values of forced vital capacity (FVC), forced expiratory volume (FEV 1-0), and peak flow rate (PFR) in children.
In children, the respiratory tract is probably more often affected by disease than any other system of the body. In spite of this, quantitative methods of evaluation are seldom used outside special respiratory units. No clinician would manage a patient with potential renal failure without laboratory aids, even if it were only an estimation of the blood urea, but he would seldom give children wi...
