No. of bitstreams: 1 Cristiane Helga Yamane de Oliveira.pdf: 734503 bytes, checksum: b1eff73874a975c200780b9676f447b3 (MD5) Previous issue date: 2016-12-13 / Introduction: Different modalities exercise lead to different magnitudes of pulse oxygen desaturation (DeSpO2) in lung diseases. Objective: To compare the exercise-induced DeSpO2 between incremental cardiopulmonary exercise test on a treadmill (TECPI-E) and the incremental shuttle walk test (ISWT) and between sub-maximum cardiopulmonary exercise test (TECPS-E) and endurance SWT (ESWT) in patients with bronchiectasis (BCT). Material and methods: 72 patients with BCT (28 men, 48 ± 15 years, FEV1:54 ± 23% of predicted) and not oxygen dependent were assessed. The order of the TECPI-E and SWTI was randomized, but not the TECPS-E and ESWT because they require that incremental tests be performed first. Treadmill and hallway tests were performed on two different visits. A reduction  4 was considered DeSpO2. Results: There was no difference in DeSpO2 between TECPI-E (-7.7% ± 6.3%) and ISWT (-6.3% ± 5.8%) and between TECPS-E (-6,8% ± 5,8%) and ESWT (-7.2% ± 6.3%). In the incremental and endurance tests, there was an agreement to DeSpO2 or not DeSpO2 in 56 and 55 patients, respectively. There was a statistically significant difference in heart rate (percentage of the maximum predicted) between TECPI-E (87.0% ± 9.0%) and ISWT (78.9% ± 11.4%) and between TECPS-E (84.5% ± 9.9%) and ESWT (79.3% ± 11.8%). However, when comparing patients who reached 85% of predicted maximum heart rate or not, there was no difference in the magnitude of DeSpO2. Conclusion: In patients with BCT, our results show that field-based tests may replace the laboratory-based tests when the clinic question is the evaluation of exercise-induced DeSpO2. / Introdução: Diferentes modalidades de exercício físico determinam diferentes magnitudes de dessaturação de pulso de oxigênio (DeSpO2) em pneumopatias. Objetivo: Comparar a DeSpO2 induzida pelo exercício entre teste de exercício cardiopulmonar (TECP) incremental em esteira (TECPI-E) e o shuttle walk test (SWT) incremental (SWTI) e entre TECP submáximo em esteira (TECPS-E) e SWT endurance (SWTE) em pacientes com bronquiectasia (BCQ). Material e métodos: Foram avaliados 72 pacientes com BCQ (28 homens, 48  15 anos, VEF1: 54 ± 23 % previsto), não dependentes de oxigênio. A ordem de realização do TECPI-E e SWTI foi randomizada, mas não o TECPS-E e SWTE, pois esses necessitam dos testes anteriores. Os testes em esteira e em corredor foram realizados em duas visitas diferentes. Uma redução  4 foi considerada DeSpO2. Resultados: Não houve diferença na DeSpO2 entre TECPI-E (-7,7% ± 6,3%) e SWTI (-6,3% ± 5,8%) e entre TECPS-E (-6,8% ± 5,8%) e SWTE (-7,2% ± 6,3%). Nos testes incrementais e de endurance, houve concordância de DeSpO2 ou não DeSpO2 em 56 e 55 pacientes, respectivamente. Houve diferença significante na frequência cardíaca (FC, % da máxima prevista) entre TECPI-E (87,0% ± 9,0%) e SWTI (78,9% ± 11,4%) e entre TECPS-E (84,5% ± 9,9% previsto) e SWTE (79,3% ± 11,8% previsto). No entanto, ao comparar os pacientes que atingiram ou não 85% da FC máxima prevista, não houve diferença na magnitude de DeSpO2. Conclusão: Nossos resultados demonstram que, em pacientes com BCQ, os testes de campo podem substituir os testes de laboratório quando a questão clínica é a avaliação da DeSpO2 induzida pelo exercício.
