“…All the measured lung function indices declined with age, as expected, as the functional efficiency of the lung deteriorates with age 18 . The present study with relatively low cumulative silica exposure has shown no significant effect, as obtained in multiple regression analysis, of increasing total cumulative exposure to respirable dust in the mine on the mean FEV 1 (% predicted), mean FEV 1 /FVC ratio and mean FVC (%predicted), but there is a significant increasing effect of total cumulative respirable dust exposure and the combined effect of smoking and total cumulative respirable dust exposure on mean FEF 25-75% (% predicted) (p=0.011 and p=0.009 respectively), while a significant increase in mean FVC was observed with smoking (p=0.020).…”

SUMMARYBackground: This is the first study in Ghana in the Obuasi gold mines where the silica content of the respirable dust is 10%, less than in previously studied gold mines, with only 23% of the miners having ever smoked. Objectives: The study was to assess the prevalence of respiratory impairment in the Ghanaian gold miner and to quantify the effects of the respirable dust on pulmonary function Design: A cross sectional epidemiological study Method: The study was carried out using MRC respiratory symptoms questionnaire, spirometry, and personal respirable dust measurements. Results: A total of 1236 miners were studied. The mean age was 39.7 ±5.8 (SD) years with a mean of 12.6 ± 6.7 (SD) years underground service and a mean total cumulative exposure to dust of 10.34 ±5.61 (SD) mg.m

“…This increase however was only empirical as there was no statistical difference between the phases of the menstrual cycle studied (figure 4). Anthropometric parameters such as age, sex, weight and height have also been documented to affect pulmonary function (Alakija et al,1990;Cotes et al,1966;Jain et al,1983) The difference in body mass indices of both groups studied (figure 5) was not statistically significant (p>0.05). Consequently, the progesterone dominance in the luteal phase is accountable for the relative enrichment in pulmonary function in this phase compared to the menstrual phase.…”

This study assessed the peak expiratory flow rate and pulse pressure during the luteal and menstruation phases of the menstrual cycle. The peak expiratory flow rate and pulse pressure were measured using the Wright's Peak Flow Meter and Mercury Sphygmomanometer respectively. The peak expiratory flow rate and pulse pressure in the luteal phase were 420.80±12.27 and 42.72±2.52 respectively. While the peak expiratory flow rate and pulse pressure in the menstruation phase were 378.40±11.85 and 35.36±1.95 respectively. The peak expiratory flow rate and the pulse pressure in the luteal phase were significantly higher (p<0.05) than the values during menstruation. The finding may be as a result of the relative increase in progesterone and estrogen levels in the luteal phase. The study thus shows an improved respiratory function and vasodilation during the luteal phase of the menstrual cycle © JASEM http://dx.doi.org/10.4314/jasem.v19i4.8

“…FEV1.0 is also defined as the maximum volume which can be expired in the first second of forced expiration after maximal inspiration (Committee on Pulmonary Physiology, A. C. C. P., 1963). However, it is not clearly defined whether the mean or the maximum value of the repeated measurements should be taken as the actual ventilatory capacity for assessment (COTES et al ., 1966;DEKROON et al, 1964;DENSEN et al, 1966 ;FERRIS et al, 1965;GILSON and HUGH-JONES, 1949 ;JOUASSET, 1960;MILLS, 1949).…”

Summary The reproducibility of ventilatory parameters of routine spirometry was statistically evaluated on three different groups of male adults, composed of 6 well-trained doctors, 30 healthy medical students, and 12 cooperative chest patients.The normal frequency distribution for VC, FEV1.0, and FEV1 .0% was established with 600 spirometric measurements on the 6 doctors, in which these spirometric values were represented as percent deviation of the mean calculated on each subject. The variations of VC, FEVI .0, and FEV 1.0 % were consistently smaller than those of MMF (FEF25-75%) and MVV.Confidence intervals of 95 % for the mean of VC, FEV1.0, FEV1.0%, MMF, and MVV were presented on each of the groups. Most 95 confidence intervals on the groups of doctors and students seemed to be smaller than those on the group of patients. Statistical analysis of the difference in 95 % confidence interval was described.The authors recommended the representation of spirometric parameters by a mean estimated from at least three successful spirometries.Routine spirometry is a widely used procedure which provides us information for the assessment of overall ventilatory capacity. Appreciable variations of the data obtained by a subject are often noticed on repeated spirometry, even though the tests are conducted satisfactorily. Since the numbers of tests to be repeated on a subject are limited in routine practice, effective approach is essential in estimating the magnitude of variation of the data in terms of the numbers of repeated tests . Precise information on qualitative and quantitative variations of the data obtained by a subject on the repeated tests must be made available for assessment of ventilatory capacity. In the present experimental observations, the reproducibility of spirometric parameters is statistically evaluated on the groups of healthy
