Ambulatory pulse oximetry monitoring in Japanese COPD outpatients not receiving oxygen therapy.

ABSTRACT:

Background

It remains unknown whether desaturation profiles during daily living are associated with prognosis in patients with chronic obstructive pulmonary disease (COPD). Point measurements of resting oxygen saturation by pulse oximetry (SpO2) and partial pressure of arterial oxygen (PaO2) are not sufficient for assessment of desaturation during activities of daily living. A small number of studies continuously monitored oxygen saturation throughout the day during activities of daily living in stable COPD patients. This study aims to analyse the frequency of desaturation in COPD outpatients, and investigate whether the desaturation profile predicts the risk of exacerbation.

Methods

We studied stable COPD outpatients not receiving supplemental oxygen therapy. Baseline asses
