RICIERI, Denise da Vinha and ROSARIO FILHO, Nelson Augusto. Assessing the impact that external factors have on respiratory mechanics assessed using a specific photogrammetric model. J. bras. pneumol. [online]. 2008, vol.34, n.9, pp. 702-706. ISSN 1806-3713. http://dx.doi.org/10.1590/S1806-37132008000900011.
This is a report on a methodological adaptation of the photogrammetric technique, which is used in other medical specialties, for use in analyzing respiratory movements. Photogrammetry and a model of photogrammetry designated biofotogrametria para análise da mecânica respiratória (BAMER, photogrammetric analysis of respiratory mechanics) were tested under previously described pathophysiological conditions: post-exercise dynamic hyperinflation using positive end-expiratory pressure. The BAMER model identified an increase in the thoraco-abdominal area following exercise using positive end-expiratory pressure. These results are comparable to those obtained with more robust systems of respiratory kinematics. The use of photogrammetry has value in many areas, since it produces quantitative data, being particularly relevant in pediatrics, in which monitoring resources are scarce.
