Background Oxygen-conserving devices have been the foundation of highly portable
oxygen systems that enable hypoxemic chronic lung disease patients to live active lives …

BACKGROUND: Ambulatory oxygen is an important component of long-term oxygen
therapy. Pulse-dose technology conserves oxygen and thus increases the operation time of …

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

Objectives: The aim of this study was to assess the performance of four demand oxygen
delivery systems (DODS) in improving oxygenation and effort tolerance, at rest and during …

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

BACKGROUND Oxygen conserving devices may lead to substantial increases in the
duration of oxygen provided. A study was undertaken to compare the performance of a …

BACKGROUND: Because standard home oxygen (O2) systems deliver O2 at fixed rates,
these systems are not designed to ensure optimal oxygen delivery based on physiologic …

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

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 …

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 …
