Many patients with chronic obstructive pulmonary disease (COPD) experience problems during performance of activities of daily living. These problems may lead to reduced physical activity. The purpose of this study was to reveal the influence on the oxygen uptakes in motion methods of hanging on laundry. Eighteen healthy females were recruited for participation in this study. They performed three kinds of movement to hang on laundry. Participants performed the following three actions: (1) hanging some towels on bars with a low stand in a sitting position (Action 1), (2) hanging some towels on bars with a low stand in a standing position (Action 2) and (3) hanging some towels on bars with a high stand in a standing position (Action 3). We measured metabolic and ventilatory requirements during these actions by use of an expires gas analyser. Mutual comparison of the three different types action showed significant differences in the oxygen uptake (VO2), carbon dioxide output (VCO2), minute ventilation (VE), and metabolic equivalents (METs). On the other hands, the differences in respiratory rate (RR) among these three actions were not significant. Action 3 tended to have the most increased values in VO2, VCO2, VE and METs. The Action 1 tended to behave the lowest value. The oxygen uptake and ventilation variables may be influenced by the methods used in hanging laundry.

Cardiopulmonary response to unloaded cycling may be related to higher workloads. This was assessed in male subjects: 18 healthy sedentary subjects (controls), 14 hypoxemic patients with chronic obstructive pulmonary disease (COPD), and 31 overweight individuals (twelve were hypoxemic). They underwent an incremental exercise up to the maximal oxygen uptake (VO2max), preceded by a 2 min unloaded cycling period. Oxygen uptake (VO2), heart rate (HR), minute ventilation (VE), and respiratory frequency (fR) were averaged every 10 s. At the end of unloaded cycling period, HR increase was significantly accentuated in COPD and hypoxemic overweight subjects (resp.,+14±2and+13±1.5 min−1, compared to+7.5±1.5 min−1in normoxemic overweight subjects and+8±1.8 min−1in controls). The fR increase was accentuated in all overweight subjects (hypoxemic:+4.5±0.8; normoxemic:+3.9±0.7 min−1) compared to controls (+2.5±0.8 min−1) and COPDs (+2.0±0.7 min−1). The plateau VE increase during unloaded cycling was positively correlated with VE values measured at the ventilatory threshold and VO2max. Measurement of ventilation during unloaded cycling may serve to predict the ventilatory performance of COPD patients and overweight subjects during an exercise rehabilitation program.

Exacerbations have significant impact on the morbidity and mortality of patients with chronic obstructive pulmonary disease. Most guidelines emphasise prevention of exacerbations by treatment with long-acting bronchodilators and/or anti-inflammatory drugs. Whereas most of this treatment is evidence-based, it is clear that patients differ regarding the nature of exacerbations and are likely to benefit differently from different types of treatment. In this short review, we wish to highlight this, suggest a first step in differentiating pharmacological exacerbation prevention and call for more studies in this area. Finally, we wish to highlight that there are perhaps easier ways of achieving similar success in exacerbation prevention using nonpharmacological tools.

Reduced Physical Activity

Skeletal muscle oxidative enzyme capacity is impaired in patients suffering from emphysema and chronic obstructive pulmonary disease. This effect may result as a consequence of the physiological derangements because of the emphysema condition or, alternatively, as a consequence of the reduced physical activity level in these patients. To explore this issue, citrate synthase (CS) activity was measured in selected hindlimb muscles and the diaphragm of Syrian Golden hamsters 6 mo after intratracheal instillation of either saline (Con, n = 7) or elastase [emphysema (Emp); 25 units/100 g body weight, n = 8]. Activity level was monitored, and no difference between groups was found. Excised lung volume increased with emphysema (Con, 1.5 ± 0.3 g; Emp, 3.0 ± 0.3 g, P < 0.002). Emphysema significantly reduced CS activity in the gastrocnemius (Con, 45.1 ± 2.0; Emp, 39.2 ± 0.8 μmol ⋅ min−1 ⋅ g wet wt−1, P < 0.05) and vastus lateralis (Con, 48.5 ± 1.5; Emp, 44.9 ± 0.8 μmol ⋅ min−1 ⋅ g wet wt−1, P < 0.05) but not in the plantaris (Con, 47.4 ± 3.9; Emp, 48.0 ± 2.1 μmol ⋅ min−1 ⋅ g wet wt−1, P < 0.05) muscle. In contrast, CS activity increased in the costal (Con, 61.1 ± 1.8; Emp, 65.1 ± 1.5 μmol ⋅ min−1 ⋅ g wet wt−1, P < 0.05) and crural (Con, 58.5 ± 2.0; Emp, 65.7 ± 2.2 μmol ⋅ min−1 ⋅ g wet wt−1, P < 0.05) regions of the diaphragm. These data indicate that emphysema per se can induce decrements in the oxidative capacity of certain nonventilatory skeletal muscles that may contribute to exercise limitations in the emphysematous patient.

Abstract Introduction. In recent times, patient outcome measurement has developed from being narrowly focussed upon levels of symptomatology and service use, to being a broader assessment of the impact of illness and treatment on the individual. Thus, it can be said that quality of life has become as significant as life expectance. This has brought about a transition in the assessment of treatment. Quality of life (QOL) is a multidimensional concept that usually includes subjective evaluations of both positive and negative aspects of life as it is being led. With regard to healthcare, a cross-sectional comparison of palliative care needs is crucial in understanding differences in the patients' quality of life. Hence, an analysis of programme implementation within different types of healthcare institutions is significant in evaluating current medical care standards. Our study analyzed the satisfaction level and quality of life of patients with Chronic Obstructive Pulmonary Disease (COPD), and after myocardial infarction (MI). Different types of healthcare institutions were evaluated. Aim. To evaluate patients' satisfaction and quality of life in selected healthcare institutions in southern-eastern Poland. Material and methods. The quality of life of patients with Chronic Obstructive Pulmonary Disease (COPD) was analyzed through the medical documentation obtained from different types of healthcare institutions. Among these are the pulmonary outpatient department in Moczary, as well as a GP Practice and a Nursing Home in this location. The quality of life of patients after myocardial infraction was analyzed through a survey study conducted at “Polonia” hospital spa in Rymanów Zdrój (the cardiology department). Results and conclusions. The post-myocardial infarction incident patients had began to care more about their health condition and the quality of life they led. Moreover, their satisfaction level from received treatment and medical care indicated that the cardiological services implemented in southern-eastern Poland has proceeded in a good direction. Of note, these patients were systematically under specialist control. In contrast, among patients with COPD, only those under everyday care in the Nursing Home in Moczary received a similar systematic treatment, thus, COPD patients in Moczary lead a poor quality of life. This indicates a need to re-evaluate the current programmes and services provided by health care institutions in this region.

Background Acute respiratory failure may develop in patients with chronic obstructive pulmonary disease because of intrinsic positive end-expiratory pressure (PEEPi) and increased resistive and elastic loads. Proportional assist ventilation is an experimental mode of partial ventilatory support in which the ventilator generates flow to unload the resistive burden (flow assistance: FA) and volume to unload the elastic burden (volume assistance: VA) proportionally to inspiratory muscle effort, and PEEPi can be counterbalanced by application of external PEEP. The authors assessed effects of proportional assist ventilation and optimal ventilatory settings in patients with chronic obstructive pulmonary disease and acute respiratory failure. Methods Inspiratory muscles and diaphragmatic efforts were evaluated by measurements of esophageal, gastric, and transdiaphragmatic pressures. Minute ventilation and breathing patterns were evaluated by measuring airway pressure and flow. Measurements were performed during spontaneous breathing, continuous positive airway pressure, FA, FA+PEEP, VA, VA+PEEP, FA+VA, and FA+VA+PEEP. Results FA+PEEP provided the greatest improvement in minute ventilation (89 +/- 3%) and dyspnea (62 +/- 2%). The largest reduction in pressure time product per breath of the respiratory muscles and diaphragm (44 +/- 3% and 33 +/- 2%, respectively) also was observed during FA+PEEP condition. When VA was added to this setting, a reduction in respiratory rate (50 +/- 3%), an increase in inspiratory time (102 +/- 6%), and a further reduction in pressure time product per minute (65 +/- 2% and 64% for the respiratory muscles and diaphragm, respectively) was observed. However, values of pressure time product per liter of minute ventilation during FA+VA+PEEP did not differ with those observed during FA+PEEP condition. Worsening of patient-ventilator interaction and breathing asynchrony occurred when VA was implemented. Conclusions Application of PEEP to counterbalance PEEPi and FA to unload the resistive burden provided the optimal conditions in such patients. Ventilator over-assistance and patient-ventilator asynchrony was observed when VA was added to this setting. The clinical use of proportional assist ventilation should be based on continuous measurements of respiratory mechanics.
