Methods: We recruited patients with chronic obstructive pulmonary disease (COPD) or
interstitial pneumonia receiving long-term oxygen therapy. Interventions were performed on …

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 …

This issue of RESPIRATORY CARE contains 2 papers of interest that deal with long-term
oxygen therapy (LTOT). In the first, Martí et al investigated the efficacy of 2 oxygen …

1.2 Objectives In this clinical trial, we will use a PULSOX Me 300 pulse oximeter with a built-
in memory function to compare SpO 2, pulse rate, walking distance, recovery time, exercise …

PURPOSE: Oxygen therapy for hypoxemic COPD patients improves survival, quality of life,
and supports exercise training. Patients periodically desaturate throughout the day, as they …

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

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 Supplemental oxygen is a recommended therapy option in stable hypoxemic
COPD patients. Often, supplemental oxygen is provided by continuous flow (CF). However …

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 …

Background and Methods Constant-minute-volume and constant-bolus devices serve as two
different means of portable oxygen conservation. A prospective randomised crossover study …
