Understanding symptoms of swimming-induced pulmonary oedema through the patient's perspective: a qualitative approach.

OBJECTIVES

Swimming-induced pulmonary oedema (SIPE)d is a potentially fatal condition that can develop in healthy individuals during swimming. Detailed descriptions of episode onset to resolution are lacking but needed to facilitate early recognition and support swimmer safety. We aimed to explore personal accounts of SIPE, focusing on the symptoms.

DESIGN

Qualitative descriptive exploratory study using semi-structured interviews.

METHODS

We subjected interview data from seventeen individuals who have experienced SIPE to thematic analysis. Sample size was guided by the concept of information power.

RESULTS

Eight symptom themes were identified, categorised under respiratory symptoms (noisy breathing, cough, chest tightness and dyspnoea) or non-respiratory symptoms (physical fatigue, altered mental state, difficulty with urination, and lack of cold perception).

CONCLUSIONS

Symptoms varied widely, and early or non-specific symptoms may be perceived as benign by swimmers who are unfamiliar with SIPE or less experienced with marathon swimming. Our findings also identified non-classical symptoms that may support early recognition.
