Patients with congestive heart failure or COPD may share an increased response in minute ventilation (V̇E) to carbon dioxide output (V̇CO2 ) during exercise. The goal of this study was to ascertain whether the V̇E/V̇CO2 slope and V̇E/V̇CO2 intercept can discriminate between subjects with congestive heart failure and those with COPD at equal peak oxygen uptake (V̇O2 ). ⋯ The ventilatory response to V̇CO2 during exercise was significantly different between subjects with congestive heart failure and those with COPD in terms of the V̇E/V̇CO2 slope with moderate-to-severe reduction in exercise capacity and in terms of the V̇E/V̇CO2 intercept regardless of exercise capacity.

Observational Study
Endurance time is the most responsive exercise measurement in idiopathic pulmonary fibrosis.
Although pulmonary rehabilitation (PR) has been reported to improve exercise capacity in patients with idiopathic pulmonary fibrosis, it is unknown which exercise measurement is the most responsive for evaluation of PR efficacy. The purpose of this study was to compare the responsiveness of 5 exercise measurements by evaluating the efficacy of PR in subjects with idiopathic pulmonary fibrosis. ⋯ ET is the most responsive exercise measurement for evaluating PR efficacy in patients with idiopathic pulmonary fibrosis.

Inhaled medications are the mainstay of treatment for maintenance of lung health in patients with cystic fibrosis (CF). Compressor/nebulizer units are used an average of 100-120 min/d by patients with CF. Each compressor/nebulizer has unique flow/pressure characteristics that affect particle size distribution and drug output rate. Few data are available regarding longitudinal performance of compressor/nebulizers. We hypothesized that their use over a 24-wk period under conditions similar to those of patients with CF would affect their performance. ⋯ Long-term use of compressor/nebulizers in a regimen similar to that of patients with CF affected their performance. Pari Vios was the most affected brand, with declines in MP and P/NEB and 2 units that stopped working. Measurement of MF and MF/NEB could help identify compressors that are likely to fail.

The aim of the present study was to assess how volume-oriented incentive spirometry applied to patients after a stroke modifies the total and compartmental chest wall volume variations, including both the right and left hemithoraces, compared with controls. ⋯ Incentive spirometry promotes increased expansion in all compartments of the chest wall and reduces asymmetric expansion between the right and left parts of the pulmonary rib cage; therefore, it should be considered as a tool for rehabilitation.

The primary aim of the disease management program (DMP) for patients with COPD is to improve health outcomes and thereby to reduce overall costs. Six years after its introduction in Germany, no consensus has yet been reached as to whether the DMP has been effective in reaching these goals. The objective of the study was an evaluation of the DMP for COPD in Bavaria using routinely collected subject medical records. ⋯ Summarizing all results leads to the suggestion that the German DMP for COPD has been effective in enhancing the quality of care in regard to an improved adherence to guidelines, pharmacotherapy, exacerbations, and self-management education. However, the DMP was not able to prevent an increase in emergency hospital admissions for the stable population in the cohort.
