Adherence to ambulatory oxygen in this series of patients is quite low but at the higher end of data reported previously. Patients with MMRC 4 dyspnoea scale had a lower use of ambulatory oxygen despite reporting better adherence to LTOT. We could not identify any other predictive factors of adherence to ambulatory oxygen.
