The aim of this study is to investigate the effects of supplemental oxygen on blood oxygenation at rest in Patients with severe to very severe COPD comparing the portable oxygen concentrat...
Objectives: The objective of this study is to determine if any differences exist between the varying modes of portable oxygen delivery systems including liquid oxygen, a portable concentr...
In COPD patients with desaturation during exercise, several studies have shown an acute beneficial effect of supplemental oxygen. Therefore, both the British Thoracic Society and the Ameri...
The purpose of this study is to compare differences in oxygen delivery between portable oxygen concentrators (POCs) and liquid oxygen (LOs) portable units, pose a question if POCs are equa...
The main purpose of this study is to learn how patients breathe on portable oxygen concentrators (POCs), and to get feedback from patients using POCs.
The heterogeneous distribution of emphysema is a key feature of chronic obstructive pulmonary disease (COPD) patients that typically is evaluated using high-resolution chest computed tomography (HRCT)...
Chronic respiratory failure (CRF) with hypoxaemia is an important pathophysiology in patients with chronic obstructive pulmonary disease (COPD), and existing mild hypoxaemia may be a sign of future CR...
Yes for exacerbations, no for hospitalizations. Prophylactic azithro-mycin reduces the number of exacerbations by about 25%. It also extends the time between exacerbations by approximately 90 days for...
Depression is a frequent comorbidity in COPD. COPD symptoms such as dyspnea may play an important role in the causal relationship between COPD and depression. We investigated the interrelations among ...
Little is known about how to achieve enduring improvements in physical activity (PA), sedentary behaviour (SB) and sleep for people with chronic obstructive pulmonary disease (COPD). This study aimed ...
The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)
Stable oxygen atoms that have the same atomic number as the element oxygen, but differ in atomic weight. O-17 and 18 are stable oxygen isotopes.
Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
Unstable isotopes of oxygen that decay or disintegrate emitting radiation. O atoms with atomic weights 13, 14, 15, 19, and 20 are radioactive oxygen isotopes.
A disease of chronic diffuse irreversible airflow obstruction. Subcategories of COPD include CHRONIC BRONCHITIS and PULMONARY EMPHYSEMA.
