BACKGROUND: The purpose of this study was to compare the ability of 3 portable oxygen
concentrators (POCs) to maintain SpO2≥ 90% during exercise in patients with chronic lung …

Oxygen May Improve Dyspnea and Endurance in Patients with Chronic Obstructive Pulmonary
Disease and only Mild Hypoxemia Page 1 Oxygen May Improve Dyspnea and Endurance in …

This essay summarizes 16 reports, published since 1956, that describe the effects of
hyperoxia on exercise endurance in persons with COPD who have severe airflow …

Objective: To determine whether transtracheal catheter and reservoir nasal cannula
contribute to maintaining adequate oxygen saturation during sleep, and to calculate the …

BACKGROUND: The development of portable liquid oxygen systems, capable of delivering
high flow rate oxygen for long periods, justifies reassessment of the value of supplemental …

A study was carried out to determine whether supplemental oxygen before exercise would
improve maximum exercise performance and relieve exertional dyspnoea in 20 patients with …

Rationale: Clinical testing of oxygen-conserving devices is not mandated before marketing.
Consequently, little is known about individual or comparative therapeutic effectiveness …

Nine patients with severe chronic obstructive lung disease with clinical and
electrocardiographic evidence of cor pulmonale were selected. They had a mean resting …

Examples of six oxygen concentrators (DeVO2, Dom 10, Econo 2, Hudson, Permox, and
Roomate) were evaluated over a 9-28 day period to determine (1) the oxygen yield (% O2) …

The influence of supplemental oxygen on exercise performance was assessed in 17
patients with severe airflow obstruction. Exercise capacity was measured by the six minute …
