Perplexityに聞いてみた。
The association between patent foramen ovale (PFO) and decompression sickness (DCI) has been studied and documented. Here is what the search results reveal:
The presence of a PFO contributes to the passage of venous gas bubbles into the arterial circulation, increasing the risk of complications related to DCI1.
Studies have shown an association between PFO and certain types of neurological and cutaneous decompression sickness34.
Epidemiological studies have demonstrated an association between PFO and certain types of neurological and cutaneous decompression illness4.
The risk of suffering major DCI events is five times higher in divers with PFO compared to those without PFO2.
Recurrent decompression illness can occur even after the closure of a PFO, indicating that the risk may persist6.
In summary, having a PFO increases the risk of developing decompression sickness in divers. The presence of a PFO allows venous gas bubbles to pass into the arterial circulation, leading to an increased risk of complications related to DCI. The risk of suffering major DCI events is higher in divers with PFO compared to those without PFO. It is important for divers with PFO to be aware of this association and take appropriate precautions.
