Background: Long-term oxygen therapy, including ambulatory oxygen, has been widely used for patients with COPD having chronic respiratory failure. However, factors important for selecting suitable carriers of ambulatory oxygen, such as a cylinder cart or backpack, remain unclear for patients with moderate-to-severe COPD. Methods: Twelve patients with moderate-to-severe COPD (mean age, 69.6 ± 7.3 years) performed a six-minute walk test (6MWT) with a cylinder cart and backpack in random order. The parameters of 6MWT with each carrier, pulmonary function test results, and a questionnaire about the preference of each carrier after 6MWTs were analyzed. Results: The Δ distance (distance walked with a backpack - that waked with a cylinder cart) positively correlated with FEV1 (r=0.678, P=0.02) and lung diffusing capacity for carbon monoxide (DLCO) (r=0.606, P=0.048).
