ABSTRACT
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. .
Objetivo Avaliar a influência da altitude no teste de caminhada de 6 minutos em pacientes com doença pulmonar moderada a grave. Métodos Vinte e nove pacientes realizaram o teste de caminhada de 6 minutos em um ambulatório de reabilitação pulmonar, na cidade de Santo André (acima do nível do mar), em São Paulo, e na praia da Enseada no Guarujá (ao nível do mar), também em São Paulo. Destes, oito pacientes realizaram tanto na areia batida como no asfalto, para avaliar a existência de alguma alteração no desempenho durante o teste. Dados como frequência cardíaca, saturação de oxigênio, distância do teste e escala de Borg foram comparados. Resultados Não encontramos diferença estatística em relação à saturação de oxigênio em repouso antes do início do teste de caminhada em Santo André 94,67±2,26% e ao nível do mar 95,56±2% (p=0,71). A saturação mínima obtida durante os testes foi de 87,27±6,54%, em Santo André, e de 89,10±5,41%, no Guarujá (p=0,098). Não houve diferença na distância percorrida e nos diferentes tipos de piso; a distância na areia foi de 387,75±5,02m e 375,00±40,88m no asfalto (p=0,654). Quanto à saturação durante a caminhada, a oximetria de pulso na areia foi de 95,12±1,80% e no asfalto foi de 96,87±1,64% (p=1,05), ou seja, o teste foi reprodutível em ambos os solos. Conclusão A altitude não influenciou o desempenho do teste de caminhada realizado por pacientes com doença pulmonar moderada a grave, sendo reprodutível tanto acima quanto ao nível do mar, mesmo ...

Objective:To observe the role of Zhike Qingfei Oral Liquid in treatment of the airway inflammation of chronic obstructive pulmonary diseases(COPD).Methods:50 cases with COPD at stable stage were divided into a treatment group and a control group,25 cases in each.Patients in both groups were treated with conventional therapy,including oxygen therapy,cardiactonic diuresis and relieving cough and asthma,etc.Zhike Qingfei Oral Liquid was added to the patients,of the treatment group,20ml each time,3 times each day,for 6 weeks.Clinical scores,pulmonary function,cell count and classification,interleukin-8(IL-8)and tumor necrosis Factor-?(TNF-?)in the sputum before and after treatment were investigated.Results:In the treatment group.the clinical score,FEV_1 and FEV_1/FVC(%)improved significantly(P
