Summary

What Researchers Did

Researchers described a case of a 54-year-old fisherman with suspected decompression sickness and used transthoracic echocardiography (TTE) to detect microbubbles and monitor his response to hyperbaric oxygen therapy (HBOT).

What They Found

The 54-year-old patient presented with dyspnea and confusion after a rapid ascent from a 50m dive, and transthoracic echocardiography (TTE) surprisingly revealed spontaneous echo contrast (microbubbles) in his right cardiac chambers. Following the first hyperbaric oxygen therapy (HBOT) session, the patient showed rapid clinical improvement, and the TTE findings of microbubbles completely resolved.

Canadian Relevance
