The Importance of Understanding Repetitive Dives

Why is it important to differentiate between repetitive dives and non-repetitive dives? During a repetitive dive, a diver is assumed to have residual nitrogen in their body from previous dives, which affects the risk of decompression sickness. Understanding this distinction is crucial for managing the safety of repetitive dives.

What is a Repetitive Dive?

A repetitive dive is a dive made while a person still has theoretical residual nitrogen in their body. This residual nitrogen accumulates with each dive and can increase the risk of decompression sickness if not properly managed.

The Risks of Repetitive Dives

Decompression sickness, also known as the bends, is a serious condition that can occur when nitrogen bubbles form in the body tissues during ascent. The risk of decompression sickness is higher in repetitive dives due to the residual nitrogen present in the diver's body.

Planning and Managing Repetitive Dives

During a repetitive dive, dive tables or dive computers are used to calculate the maximum dive time and ascent rate based on the diver's theoretical residual nitrogen. This helps in preventing decompression sickness and ensuring the safety of the dive.

Precautions for Repetitive Dives

Divers and dive operators must take precautions such as monitoring dive times, surface intervals, and ascent rates to minimize the risk of decompression sickness during repetitive dives. Proper training and adherence to diving protocols are essential for safe repetitive diving practices.
