[Comparison of 14-day rehabilitation and oxygen therapy on exercise tolerance and percutaneous oxygen saturation in patients with advanced COPD]. / Porównanie wplywu 14 dniowej rehabilitacji i tlenoterapii na tolerancje wysilku i wysycenie krwi tetniczej tlenem u chorych na zaawansowana POCHP.

UNLABELLED: Whether rehabilitation may be as beneficial as oxygen therapy (T) in the management of chronic obstructive pulmonary disease (COPD) is still not known. The aim of the was to compare the effects of T or R on exercise tolerance (ET) and percutaneous oxygen saturation (SO2) at rest and at the peak exercise in 21 patients with COPD (FEV1, 1.29 L +/- 0.5) Eleven patients with COPD were treated with oxygen (17 hour per day) for 14 days and 10 patients were rehabilitated. Both groups did not differ in age 63.7 vs 69.3 years, in the baseline values of FEV1, PaCO2 and PaO2 and resting SO2%. Before the study patients R and T had similar resting SO2 values and ET (4.5 +/- 1 vs 3.4 +/- 2 METs, p = NS), but those in the R group revealed higher drop in SO2 at peak exercise test (10.9 vs 3.4%, p = 0.007). RESULTS: We found no significance impact of 14- day R and 14- day T on results of exercise test and exercise pulse oximetry in studied patients. However, rehabilitated patients, as opposite to patients on oxygen therapy had tendency to increase number of Mets and to diminish maximal drop in pulse oximetry during exercise. As a result, when we compared group R i T after study patients of R group differed from T patients with number of METs achieved (4.6 vs 3.0, p = 0.02), whereas maximal drop in SO2 at the peak exercise test in R and T patients equalized (7.9 +/- 7 vs 3.2 +/- 3%, p = NS). We conclude that the results of our short term study may suggest better effects of rehabilitation than oxygen therapy on exercise tolerance and oxygen saturation during exercise in COPD patients and justify further studies.

[The impact of 2-year rehabilitation on exercise tolerance and transcutaneous oxygen saturation during exercise in patients with chronic obstructive pulmonary disease]. / Wplyw 2-letniej rehabilitacji na tolerancje wysilku i wysycenie tlenem krwi tetniczej w czasie wysilku u chorych na przewlekla obturacyjna chorobe pluc.

We compared results of symptom-limited exercise test (ET) and percutaneous oxygen saturation (SaO2) during ET in rehabilitated COPD patients (R) and in control COPD patients (C) before and after 2 years of study. Group of R consisted of 27 patients (FVC 2.15 l, FEV1 1.17 l, mean age 58, range 32-76 years) who underwent comprehensive, in-hospital and domestic R, group C consisted of 19 patients (FVC 1.95 l, FEV1 1.42 l, mean age 68, range 55-83 years). The studied groups did not differ in their FVC and FEV1, but R patients were younger (p = 0.05), had more sustained ET (p = 0.0002) and greater number of METs achieved during ET (p = 0.0008). After study we found increased number of METs during ET from 3.94 to 4.77, p = 0.003, improved 10 grade Borg score in 3' ET from 4.0 to 2.5, p = 0.05 and tendency to decrease maximal drop of SaO2 during ET from 6.8 to 3.1% (NS). Patients in C group failed to improve results of ET: from 2.7 to 2.5 METs (NS), and pulse oximetry: maximal drop in SaO2 during ET from 3.1 to 3.07%, NS) and also 10-grade Borg score in 3'ET (from 2.0 to 2.8, NS). In conclusion, although differences in age and in initial exercise tolerance between studied groups could influence the results of this study, it seems that long term rehabilitation can improve both exercise tolerance and oxygen saturation during exercise in COPD patients.

[Respiratory rehabilitation of patients with chronic obstructive lung diseases in the subjective and objective evaluation]. / Rehabilitacja oddechowa u chorych z przewlekla obturacyjna choroba pluc w ocenie subiektywnej i obiektywnej.

An intensive 14 day respiratory rehabilitation program was carried out in 24 COPD patients of mean age 66.0 +/- 10.0 yrs (FVC 1.56 +/- 0.52 L, FEV1 0.94 +/- 0.4 L/s). A statistically objective improvement was seen measured by the 100 meter tread mill test (p = 0.001) which was not seen in spirometric analysis. Seventeen patients reported a subjective improvement in their clinical state. The authors have demonstrated usefulness of the 100 meter walk test in analysis of rehabilitation processes.
