When do AGE symptoms usually occur after an incident?

When considering the onset of symptoms for arterial gas embolism (AGE), it is well-established that the symptoms typically manifest within a short time frame following an incident, particularly when diving practices are involved. Immediate symptoms can occur as quickly as 15 minutes after the incident, making this time frame critical.

The nature of AGE, which involves bubbles forming in the bloodstream due to rapid ascent or other diving-related issues, means that the body often reacts swiftly as it encounters these gas bubbles. This quick reaction is essential for divers and medical personnel to understand, as it underscores the urgency of recognizing and addressing symptoms immediately after a diving event.

While there can be variations in cases, such as occasional delayed reactions, the standard expectation is that symptoms will occur relatively quickly. The later onset of symptoms (up to six hours or even delayed up to 24 hours) is less common and can mislead divers into underestimating the urgency of their situation if symptoms are not present immediately after a deep dive, potentially leading to dangerous consequences.

In diving first aid training, recognizing the rapid onset of AGE symptoms is crucial for effective response and treatment strategies, which can significantly improve outcomes in affected individuals.
