Lung volumes and ventilatory flows: report of Working Party.
In § 3.5.1.6. the authors emphasize the importance of adequate temperature measurement in the spirometer. However, temperature stability is also important. When a patient breathes in a spirometer, heat is dissipated due to various sources, the heat of reaction in the CO2-absorber being the most important. The resulting increase in temperature is counteracted by the heat capacity of the instrume...
متن کاملForced expiratory flows' contribution to lung function interpretation in schoolchildren.
Forced expiratory flow (FEF) at low lung volumes are supposed to be better at detecting lung-function impairment in asthmatic children than a forced volume. The aim of this study was to examine whether FEF results could modify the interpretation of baseline and post-bronchodilator spirometry in asthmatic schoolchildren in whom forced expiratory volumes are within the normal range. Spirometry, w...
متن کاملLung volumes, ventilatory capacity, and transfer factor in healthy British boy and girl twins.
Cotes, J. E., Dabbs, J. M., Hall, A. M., Axford, A. T., and Laurence, K. M. (1973). Thorax, 28, 709-715. Lung volumes, ventilatory capacity, and transfer factor in healthy British boy and girl twins. Normal values are reported for the lung volumes, ventilatory capacity, and transfer factor of 212 healthy British twin children aged 8 to 16 years. The boys and the girls share a common relationshi...
متن کاملAlmost Periodically Forced Circle Flows
We study general dynamical and topological behaviors of minimal sets in skewproduct circle flows in both continuous and discrete settings, with particular attentions paying to almost periodically forced circle flows. When a circle flow is either discrete in time and unforced (i.e., a circle map) or continuous in time but periodically forced, behaviors of minimal sets are completely characterize...
متن کاملForced expiratory flows and volumes in intubated and paralyzed infants and children: normative data up to 5 years of age.
Reference equations that express indexes obtained from forced expiratory maneuvers in relation to height and/or other independent variables are lacking for infants and children with artificial airways. The present study was performed to establish normative data of forced expiration by forced deflation in healthy intubated and paralyzed infants and children and to develop prediction equations in...
