Automatic oxygen titration versus constant oxygen flow rates during walking in COPD: a randomised controlled, double-blind, crossover trial.

ABSTRACT:

Rationale

In patients with COPD, oxygen (O₂)-supplementation via a constant flow oxygen system (CFOS) can result in insufficient oxygen saturation (SpO₂ <90%) during exercise. An automatically titrating O₂-system (ATOS) has been shown to be beneficial compared with an untitrated CFOS, however, it is unknown if ATOS is superior to CFOS, titrated during exercise as stipulated by guidelines. The aim was to investigate the effects of ATOS compared with titrated CFOS on walking capacity in people with hypoxaemic COPD.

Methods

Fifty participants completed this prospective randomised controlled, double-blind, crossover trial. Participants performed two endurance shuttle walk tests (ESWTs) with: (1) exercise titrated CFOS (ESWT_CFOS) and (2
