An exploration of patients’ memories and experiences of hyperbaric oxygen therapy in a multiplace chamber

Abstract

AIMS AND OBJECTIVES: To examine patients' memories and experiences of hyperbaric oxygen therapy in a multiplace chamber of a hyperbaric medicine unit in Australia. BACKGROUND: There is minimal literature available documenting patients' feelings and memories of hyperbaric oxygen therapy, particularly in a multiplace chamber. DESIGN: Exploratory. METHODS: A convenience sample of seven non-emergency patients was interviewed separately at the conclusion of their multi-session therapy. A semi-structured approach elicited in-depth information regarding their experiences and memories of the hyperbaric oxygen therapy. Interviews were 30-45 minutes long and audiotaped for transcription and analysis. Field notes were also used to note non-verbal cues and other observations not evident from the audio material. Data collection ceased when data saturation was evident from the interviews. Interview transcripts were examined using a content analysis approach, with textual coding and thematic development. RESULTS: Issues derived from the data included: the uncertainty of the treatment; the noise and cold of the chamber; the discomfort of the mask or hood; and the boredom. Participant responses to the therapy related to previous noxious experiences and the individual's personality. CONCLUSIONS: This information was used to examine ways of reducing any negative feelings and experiences associated with hyperbaric oxygen therapy, thus improving the service provided to patients. RELEVANCE TO CLINICAL PRACTICE: Identification of these stressors and related issues may also enable subsequent development of a risk-stratification instrument to predict patients who do not complete treatment.
