Impacto de fatores externos sobre a mecânica respiratória avaliada por um modelo fotogramétrico específico: biofotogrametria

Abstract

research, have been successfully used in the analysis of body segment movements in functional or diagnostic activities in other medical specialties, (2,5) principally in orthopedics and neurology. 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. (11) The type of photogrammetry used in study (5,12,13) represents a promising trend, whose operational differentiation from traditional photogrammetry is in the methodological improvement for the analysis of respiratory movement.This communication presents the performance of photogrammetry in the identification of quantitative alterIn pulmonology, although impairment of the respiratory mechanics is not restricted to individuals with respiratory diseases, (1) it can produce results of relevant proportions in such individuals. 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.

Thoracoabdominal mobility evaluation by photogrammetry in newborns after expiratory flow increase technique

“…Unlike the previously mentioned systems, biophotogrammetry stands out as a versatile and easily adaptable mechanism for several areas (10). Its use allows the geometric delimitation of thoracoabdominal compartments from the extension of the thoracic wall and its thoracic and abdominal subcompartments (6,10,11).…”

“…Its use allows the geometric delimitation of thoracoabdominal compartments from the extension of the thoracic wall and its thoracic and abdominal subcompartments (6,10,11). As an ascending technique, it has two ways of evaluation, photogrammetry and videogrammetry, that evaluate kinematics of body movements by a set of photos and video acquisition, respectively, and it may be used in two-dimensional (2D) or three-dimensional (3D) evaluation (12,13).…”

Intra- And Inter-Rater Reliability of a Biophotogrammetric Assessment Protocol for Preterm Infants

“…14,15 Nevertheless, we found no reliability and reproducibility measurements for the existing protocols, which restricts their bedside use. 14,15 Besides, the variables still do not answer all questions that arise in clinical practice and are difficult to measure in daily routine. 14,15 These considerations justify the creation of a new protocol with the performance of a reliability and reproducibility analysis to substantiate its informed and safe use in the preterm infant population.…”

“…It uses markers placed on anatomical reference points to measure different angles and distances. 15 Since this tool has proven to be versatile and easy to adapt to different areas of medicine, 15 it has gained relevance in several age groups, especially for evaluating the thoracic area. 14,15 Nevertheless, we found no reliability and reproducibility measurements for the existing protocols, which restricts their bedside use.…”
