In pulmonology, such systems provide biomechanical, (6) morphometric (7) and kinematic evidence, (8)(9)(10)(11) involved in respiratory diseases or not, and can be applied in different scenarios while maintaining quality and reproducibility.

To study the kinetic aspects of respiratory pathology, one must have knowledge of respiratory mechanics and kinematics in order to identify and quantify imbalances of the respiratory muscles, as well as seeking out new technologies, (2) as observed in other medical specialties. Equipment for objective monitoring (1,3) is scarce, and those developed in laboratories are occasionally incompatible with the Brazilian public health care system scenario.In this panorama, movement analysis systems using imaging, whose adaptation (4) as a noninvasive monitoring technique has gained ground in state-of-the-art Assessing the impact that external factors have on respiratory mechanics assessed using a specific photogrammetric model* Impacto de fatores externos sobre a mecânica respiratória avaliada por um modelo fotogramétrico específico: biofotogrametria
Denise da Vinha Ricieri 1 , Nelson Augusto Rosário Filho 2 AbstractThis 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.Keywords: Biomechanics; Photogrammetry; Respiratory mechanics; Thoracic wall.
