What is the typical onset time for Type 1 decompression sickness after resurfacing?

Type 1 decompression sickness, also known as mild decompression sickness, typically presents with symptoms after a period of exposure to changes in pressure, such as those experienced when resurfacing from depths while diving. The onset of symptoms is usually observed within a specific time frame, which is commonly understood to be within 6 hours following the return to surface pressure.

This time frame is crucial for recognition and management of the condition, as it allows for timely intervention which can help reduce complications and promote recovery. Symptoms can include joint pain, rashes, and fatigue, reflecting the breakdown of nitrogen bubbles in the tissues as pressure changes occur.

Understanding this timeline helps medical professionals and athletes alike recognize and respond to early signs of decompression sickness, ensuring prompt treatment and care.
