Changes in lung ultrasound presentation induced by breath-hold diving in a simulated depth competition at Taiwan

Key Points

• The aim is to investigate lung ultrasound changes and respiratory symptoms in breath-hold divers during a simulated depth competition.
• Conducted lung ultrasound assessments post-dive
• Monitored participants for acute respiratory symptoms
• Measured diving depth and correlated it with B-line scores
• 28% of divers experienced acute respiratory symptoms post-dive
• 8% showed signs of interstitial pulmonary edema (IPO)
• 40% had positive lung ultrasound findings despite being mostly asymptomatic
• Significant correlation between maximum diving depth and increased B-line scores
