The mean flow rate for prescribed oxygen was 1.10 L\/min at rest and 2.96 L\/min under exertion. Median duration of use was 17.5 months. Built\u2010in battery type, environmentally friendly system and voice guidance system received the most attention according to four\u2010grade evaluations of each function. Significant differences were seen in design features in patients less than 72 years old (<jats:italic>P<\/jats:italic>\u2009=\u2009.03), in voice guidance system in patients who only used the equipment during exertion (<jats:italic>P<\/jats:italic>\u2009=\u2009.01), and in brand imaging in those using the equipment under exertion at a flow \u22653 L\/min (<jats:italic>P<\/jats:italic>\u2009=\u2009.04).
