NCT06984120 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 609

Last updated 2026-02-18

No results posted yet for this study

Summary

Previous studies suggest that increased extravascular lung water might be found in open water swimmers without respiratory symptoms. This study aims to investigate a large number of asymptomatic individuals after an open-water swimming race to assess the prevalence of increased extravascular lung water in asymptomatic open-water swimmers.

Conditions

  • Pulmonary Edema - Acute
  • Extravascular Lung Water

Interventions

DIAGNOSTIC_TEST

Lung ultrasound

Four chest regions for both lungs are scanned by lung ultrasound; a positive region defined by the presence of three or more B-line artifacts. Bilateral or unilateral presence of two or more positive regions define positive interstitial syndrome.

DIAGNOSTIC_TEST

Peripheral oxygen saturation

Peripheral oxygen saturation measured by non-invasive pulse oxymetry

DIAGNOSTIC_TEST

Lung auscultation

Clinical auscultation of lungs

DIAGNOSTIC_TEST

Body temperature

Body temperature measured by ear thermometer.
