Walking with Non-Invasive Ventilation Does Not Prevent Exercise-Induced Hypoxaemia in Stable Hypercapnic COPD Patients.
Non-invasive positive pressure ventilation (NPPV) in addition to supplemental oxygen improves arterial oxygenation, walking distance and dyspnea when applied during exercise in stable hypercapnic COPD patients. The aim of the current study was to investigate whether NPPV without supplemental oxygen is capable of preventing severe exercise-induced hypoxemia in these patients when applied during walking. ⋯ The use of NPPV during walking without the application of supplemental oxygen does not prevent exercise-induced hypoxemia in patients with stable hypercapnic COPD.

Effects of Whole Body Vibration in Patients With COPD.
Whole body vibration training (WBVT) improves muscle force in healthy subjects. Resistance training (RT) is an important component of a pulmonary program. ⋯ WBVT after 15 min aerobic training enhances 6MWD, Wmax and QoL in COPD patients; however only 30% of patients reached the MCID for 6MWD.

There is little evidence that the guideline-recommended oxygen saturation of 92% is the best cut-off point for detecting hypoxemia in COPD exacerbations. ⋯ Our results support current recommendations for ordering blood gasometry based on pulse oximetry oxygen saturation cut-offs for hypoxemia. We also provide easy to use formulae to calculate pO2 from oxygen saturation measured by pulse oximetry.

There is a paucity of population-based data on COPD prevalence and its determinants in Bangladesh. ⋯ COPD is a highly prevalent and grossly underdiagnosed public health problem in Bangladeshi adults aged 40 years or older. Illiteracy, smoking and biomass fuel burning are modifiable determinants of COPD.

Chronic Obstructive Pulmonary Disease exacerbations are associated with worsening of airway inflammation, the nature of which may be neutrophilic, eosinophilic, or both. ⋯ This non-intervention study suggests that the cellular nature of bronchitis is largely unpredictable and needs to be examined at each COPD exacerbation This has important implications in choosing the appropriate therapy. Future intervention studies would provide further evidence.
