Recent heightened concern about the costs of medical care has stimulated research and
development in devices and schemes for saving costs while retaining quality of care …

BACKGROUND: Demand oxygen delivery systems (DODS) allot oxygen by interrupting the
oxygen flow during exhalation, when it would mostly be wasted. Because DODS conserve …

Supplemental oxygen is a marvelous “drug,” with several rather unique beneficial
physiologic effects. It produces well-documented long-term benefits when administered to …

BACKGROUND: Portable oxygen concentrators (POCs) deliver oxygen in intermittent
pulses. The challenge of establishing equivalence between continuous flow oxygen and …

Demand oxygen systems have been shown to be effective in treating hypoxemia during
seated rest and during exercise, but the performance of these systems during sleep has not …

The purpose of this study was to compare the efficacy of nasal oxygen delivery by an
inspiratory demand valve, which delivers oxygen only during the inspiratory phase, to …

Multiple benefits of oxygen therapy for hypoxemic patients with chronic lung disease are
well established. Steady flow oxygen therapy is inefficient, wasteful and has a high cost. The …

Oxygen therapy is one of the most frequently ordered therapies for patients with chronic
obstructive pulmonary disease (COPD). In a large percentage of these cases, oxygen …

BACKGROUND: Currently available methods for conserving oxygen include transtracheal
catheters, reservoir cannulae, and demand oxygen delivery systems (DODS). DODS do not …

BACKGROUND: Oxygen titration is recommended to avoid hyperoxemia and hypoxemia.
Automated titration, as well as the S pO 2 target, may have an impact on oxygen utilization …
