Effects of Supplemental Oxygen Delivered by a Portable Oxygen Concentrator Compared to a Liquid Oxygen Device in COPD

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...

Prospective Study Comparing Different Modalities of Oxygen Delivery During Assessment of Functional Exercise Capacity

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...

Effect of Oxygen in Normoxaemic COPD Patients Who Desaturate During Exercise

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...

Oxygen Portable Concentrator During Exercises in Patients With COPD

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...

Portable Oxygen Concentrator Signal Capture Study

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.

Obesity in COPD: Comorbidities with Practical Consequences?

COPD and obesity often coexist and there is a complex interaction between them. Our aim was to evaluate the prevalence of obesity in a secondary care COPD population. Furthermore, the presence of como...

Complementary regional heterogeneity information from COPD patients obtained using oxygen-enhanced MRI and chest CT.

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)...

Annual decline in arterial blood oxygen predicts development of chronic respiratory failure in COPD with mild hypoxaemia: A 6-year follow-up study.

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...

Clinical Inquiries: Does prophylactic azithromycin reduce the number of COPD exacerbations or hospitalizations?

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...

Impact of adherence to long-term oxygen therapy on patients with COPD and exertional hypoxemia followed for one year.

To determine the impact of adherence to long-term oxygen therapy (LTOT) on quality of life, dyspnea, and exercise capacity in patients with COPD and exertional hypoxemia followed for one year.

Medical and Biotech [MESH] Definitions

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.
