Precisão e acurácia da cirtometria em adultos saudáveis

Abstract

Objective: To determine the intrarater and interrater reliability of cirtometry (measurements of the circumference of the chest and abdomen taken during respiratory movements) as well as its correlation with pulmonary volumes measured by respiratory inductive plethysmography. Methods: A total of 40 healthy individuals were evaluated. The mean age was 28 years. The measurements were taken in the supine position at three different time points: at rest, at maximal inspiration, and at maximal expiration. Two trained investigators, each of whom was blinded as to the results obtained by the other, performed the measurements. The Friedman test was used to determine intrarater reliability, and the Wilcoxon test, together with the intraclass correlation coefficient, were used to determine interrater reliability. The correlation between the cirtometry measurements and the plethysmography results was obtained using Spearman's correlation coefficient. The level of significance was set at 0.05 for all tests. Results: Intrarater reliability was satisfactory. Regarding interrater reliability, statistically significant differences (2.8 cm at the most) were found in all sets of measurements. However, through the analysis of the intraclass correlation coefficient, the investigators were found to be responsible only for a small portion of the variability (1.2-5.08%) found among the measurements. When the cirtometry measurements were compared to the volumes measured by respiratory inductive plethysmography, low correlations (range, r = 0.170-0.343) were found. Conclusions: The findings of this study suggest that, although cirtometry is a reliable measurement, it does not accurately measure pulmonary volumes.

Espirometria de incentivo a volume versus a fluxo sobre parâmetros respiratórios em idosos

“…In dorsal decubitus, the tapes were placed in three anatomical reference points -axillary fold, xiphoid appendix and umbilical line, and measurements were taken at rest, after maximal inspiration (TLC) and after maximal expiration (RV), commanded by the researcher. For each point there were three measurements, at three different moments, with one-minute intervals between them 13 . Current volume (CV), respiratory frequency (RF), Minute Volume (MV), Forced Vital Capacity (FVC) and Forced Expiratory Volume in the first second (FEV 1 ) were obtained with the spirometer Respiradyne II (Model 5-7930P Sher Wood Medical Co).…”

Estudo dos volumes pulmonares e da mobilidade toracoabdominal de portadoras de obesidade mórbida, submetidas à cirurgia bariátrica, tratadas com duas diferentes técnicas de fisioterapia

“…Although it was not possible to evaluate the variables in a group without physical therapy intervention, such as a control group, these results can be attributed to the physical therapy intervention because, in most of the literature references, there is a postoperative reduction in the variables [6][7][8]11 . The changes in volume also indicate a relationship with the thoracic and abdominal mobility changes verified by cyrtometry, although it is not an appropriate form of measuring pulmonary volumes 20 . Cyrtometry or thoracoabdominal perimetry, which consists of a group of chest and abdominal circumference measurements, has the purpose of evaluating thoracic expandability and can be carried out in a simple and accessible way 21 .…”

“…Cyrtometry or thoracoabdominal perimetry, which consists of a group of chest and abdominal circumference measurements, has the purpose of evaluating thoracic expandability and can be carried out in a simple and accessible way 21 . This technique is considered a valid measure for analyzing the dimensions and widths of thoracic and abdominal movements 20 . Although seldom referred to in the literature, this measuring technique is widely used in clinical physical therapy practice to evaluate abdominal and thoracic mobility during respiratory movements 22 .…”

Comparação De Dois Protocolos De Espirometria De Incentivo No Pós-Operatório De Cirurgia De Revascularização Do Miocárdio: Estudo Piloto

“…Foram mensurados os perímetros torácicos nos níveis axilar e xifoide e o abdominal no nível da cicatriz umbilical 12 . Os pacientes foram incentivados verbalmente a realizar uma expiração máxima seguida de uma inspiração lenta e profunda, momento em que se verificou o valor da circunferência inspiratória e, na sequência, solicitou-se uma expiração máxima momento em que foi verificado o valor da circunferência expiratória em cada nível de medição 11,13 .…”
