Objective To evaluate the influence of the altitude on the 6-minute walking test in patients with moderate to severe pulmonary disease.Methods Twenty-nine patients performed the 6-minute walk test at a pulmonary rehabilitation clinic in Santo André (above sea level), in São Paulo State, and at the Enseada Beach, in Guarujá (at sea level), also in São Paulo State. Of these 29 patients, 8 did the test both on hard sand and on asphalt to analyze if there were differences in performance during the tests. Data such as heart rate, oxygen saturation, test distance, and Borg scale were compared.Results We found no statistical difference in relation to oxygen saturation at rest before the beginning of the walking test in Santo André 94.67±2.26% and at sea level 95.56±2% (p=0.71). The minimum saturation measured during the test was 87.27±6.54% in Santo André and 89.10±5.41% in Guarujá (p=0.098). There were no differences in the performed distance between the different kinds of terrains; the distance on sand was 387.75±5.02m and on asphalt it was 375.00±6.54m (p=0.654). Regarding oxygen saturation during walking, the pulse oximetry on sand was 95.12±1.80% and on asphalt it was 96.87±1.64% (p=1.05).Conclusion Altitude did not affect the performance of the walking test in patients with moderate to severe pulmonary disease and the results were similar in both cases, on sand and on asphalt.

Objective To evaluate self-esteem and self-image of respiratory diseases patients in a Pulmonary Rehabilitation Program, who participated in socialization and physical fitness activities, and of patients who participated only in physical fitness sessions.Methods A descriptive cross-sectional exploratory study. Out of a total of 60 patients analyzed, all enrolled in the Pulmonary Rehabilitation Program, 42 participated in at least one of the proposed activities, 10 did not participate in any activity and 8 were excluded (7 were discharged and 1 died).Results When the two groups were compared, despite the fact that both demonstrated low self-esteem and self-image, the difference between them was relevant (p<0.05) regarding self-esteem, indicating that those who participated in the proposed socialization activities had better self-esteem than the individuals who only did the physical fitness sessions. Regarding self-image, the difference between the groups was not relevant (p>0.05).Conclusion The Pulmonary Rehabilitation Program patients evaluated presented low self-esteem and self-image; however, those carrying out some socialization activity proposed had better self-esteem as compared to the individuals who did only the physical fitness sessions.

Objetivo: Comparar o desempenho dos pacientes com DPOC no Teste de Caminhada de 6’, com a utilização do concentrador Portátil (pulsado/ contínuo) e Cilindro. Métodos: Trata-se de um estudo piloto observacional, foram recrutados 20 pacientes com DPOC, participantes do Ambulatório de Reabilitação Pulmonar do Centro Universitário FMABC. Os participantes foram submetidos à avaliação, realizaram o Questionário COPD Assessment Test  e o teste de caminhada de seis minutos com uso do cilindro de oxigênio e com concentrador portátil Concentrador De Oxigênio Portátil SimplyGo - Philips Respironics®  em modo contínuo (CPC) e concentrador portátil de modo pulsado (CPP). Foram verificadas a saturação de oxigênio (SpO2) e a frequência cardíaca (FC) por meio de um oxímetro portátil.  Os parâmetros aferidos antes e depois do teste foram os seguintes: (I) Pressão Arterial (PA), (II) FC, (III) SpO2 e (IV) Escala de Borg. Resultados: Quando comparadas as variáveis (SatO2, FC, Borg dispneia e MMII) em todos os momentos dos TC6’ nas diferentes formas de fornecimento, não houve diferença significativa, o que sugere que as fontes de O2 têm equiparidade no uso em pacientes com DPOC. Conclusões: o presente estudo sugere que os diferentes dispositivos de oxigênio CPC, CPP, C utilizados no TC6’, se mostraram equivalentes no desempenho e na performance física dos pacientes com DPOC.
