What do divers need to consider when calculating their no stop limits?

Their previous dive history
The type of dive gear used
The dive's water conditions
The total number of divers present

The correct answer is: Their previous dive history

When calculating no stop limits, divers need to consider their previous dive history. This is essential because residual nitrogen from past dives can affect how much time a diver can safely spend at a certain depth without requiring a decompression stop on subsequent dives. The body's nitrogen levels build up during diving, particularly in deeper and longer dives, so understanding a diver's recent exposure to pressure and time spent underwater allows for safer planning of future dives, ensuring divers do not exceed their no stop limits and risk decompression sickness. Considering the previous dive history is crucial in creating a safe dive profile that accounts for potential nitrogen loading in the body. This careful consideration helps divers to manage their overall exposure to pressure changes effectively, reducing the risk of diving-related injuries.
