The role of pulse oximeter in anxiety and exacerbations in COPD patients: A prospective observational study

Pulse oximeter use was not associated with anxiety or symptom severity among the patients with COPD receiving LTOT. However, non-use of pulse oximeter was independently associated with increased non-exacerbation-related hospital admissions. These findings suggest that pulse oximeter may support patient self-management and reduce unnecessary healthcare utilization, without contributing to anxiety.
