Patients
Forty-four patients with severe airflow obstruction (FEV1 <50 percent of predicted) were admitted to a pulmonary rehabilitation center for physical training and participated in the study. All patients were in stable clinical condition and were not suffering from a lower respiratory tract infection.
Methods
Body height was measured standing barefoot and was determined to the nearest 0.5 cm. Body weight was measured with a beam scale without shoes in light clothing to the nearest 0.1 kg (SECA). Body
Results
A description of the study group is given in Table 2. The weight-stable and weight-losing groups with a resting PaO2 of 7.3 kPa or more were significantly different in age and pulmonary function. Even more compromised values for IVC, FEV1, and Pimax were found in the hypoxemic patients. Mean values of baseline SaO2, meal SaO2, and after-meal SaO2 of meal 1 for the three groups are graphically displayed in Figure 1. Baseline SaO2 was significantly lower in the hypoxemic relative to the
Discussion
Nutritional management of COPD is difficult and controversial. Several factors have been suggested in the literature that may interfere with dietary intake in COPD, such as gastrointestinal disorders, psychosocial factors, and meal-related oxygen desaturation.2 In this study, we addressed the immediate effect of eating on SaO2. Furthermore, we were interested in the effect of the carbohydrate content of a meal on PaCO2 because it has been suggested to patients with COPD to shift from

2016, Respiratory MedicineCitation Excerpt :High doses of dietary supplements can lead to side effects such as bloating or gas and diarrhoea [44]. Patients with COPD may run a risk of desaturation and arterial hypoxia in connection with meals, which can hamper nutritional treatment [61,62]. Low compliance: Compliance with nutritional supplement prescriptions is poor in outpatient care [31,43].
