Forced expiratory indices in normal Libyan men.
Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio in the first second (FEV1% VC), forced expiratory flow between 200 and 1200 ml (FEF200-1200), and forced mid expiratory flow between 25% and 75% of FVC (FMF) were measured in 275 Libyan men ranging from 20 to 60 years. All values were lower with increasing age and, apart from FEV1% VC, were posit...
متن کاملForced expiratory indices in normal Libyan children aged 6-19 years.
Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured in 796 Libyan children (386 boys and 410 girls) with ages ranging from 6 to 19 years. Values in girls were significantly less than those in boys after allowance had been made for age and height. FVC and FEV1 correlated best with standing height but were also correlated with body weight. These results may...
متن کاملPeak expiratory flow rates in Libyan adolescents.
Peak expiratory flow rates of 578 Libyan boys and 527 Libyan girls aged 12 to 21 years were determined. The prediction formulae that best describe the data are as follows: Boys: PEFR = 160 X Stature 1.87 Girls: PEFR = 130 X Stature2.44 Statistically significant correlations were found between peak expiratory flow rate (PEFR) and standing height, sitting height, body mass index, body surface are...
متن کاملForced expiratory volume in 1 second and cognitive aging in men.
OBJECTIVES To evaluate forced expiratory volume in 1 second (FEV(1) , a measure of overall lung function), long-term average FEV(1) , and rate of decline in FEV(1) in relation to cognition and cognitive decline in older men. DESIGN Prospective observational study. SETTING Community-based population. PARTICIPANTS Eight hundred sixty-four older men from the Normative Aging Study. MEASUREM...
متن کاملPerformance of forced expiratory manoeuvre in children.
The negative expiratory pressure (NEP) method has been previously used to assess the performance of forced vital capacity (FVC) manoeuvre in normal adults. The aim of the present study is to assess whether flow limitation is achieved during FVC manoeuvres in children aged 6-14 yrs. NEP (-10 cmH2O) was successfully applied in 177 normal children, the portion of FVC over which expiratory flow did...
