BACKGROUND: In this study, we conducted a questionnaire survey to clarify and improve problems related to oxygen concentrators.
METHODS: Using a questionnaire survey of 30 patients receiving long-term oxygen therapy for chronic respiratory failure, we investigated the necessity of using a remote controller, portability, fire prevention system, built-in battery type and so on. Patients were divided into two groups according to age, sex, underlying conditions and amount of oxygen prescribed, then analyzed accordingly.
RESULTS: Mean age was 72.3 ± 8.09 years. 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-in battery type, environmentally friendly system and voice guidance system received the most attention according to four-grade evaluations of each function. Significant differences were seen in design features in patients less than 72 years old (P = .03), in voice guidance system in patients who only used the equipment during exertion (P = .01), and in brand imaging in those using the equipment under exertion at a flow ≥3 L/min (P = .04). In questionnaire results for the three most desired features, built-in battery type was of primary concern, followed by portability and use of a remote control.
CONCLUSIONS: Overall, built-in battery type, portability, use of a remote control and an environmentally friendly system were desired features for oxygen concentrators. Desired features could vary according to age and the amount of oxygen prescribed.
