What is the recommended surface interval between multiple dives during a day that require decompression stops?

The recommended surface interval between multiple dives that require decompression stops is more than 24 hours. This lengthy surface interval is necessary to allow the body ample time to off-gas and eliminate any residual nitrogen that has accumulated in the tissues from the earlier dives.

When divers perform consecutive dives, particularly those that require decompression, the nitrogen absorbed during the dives can create a risk of decompression sickness (DCS) if not managed properly. The more time spent at the surface allows for safer diving practices and reduces the likelihood of nitrogen loading, which can occur during multiple dives in a short period.

This guideline is crucial for maintaining diver safety and ensuring that the body can effectively manage the nitrogen levels without increasing the risk of DCS or related complications.
