Why is it important to monitor depth, time, and breathing gas constantly during deep diving?

Monitoring depth, time, and breathing gas continuously during deep diving is essential for ensuring safety and compliance with dive tables. By keeping a close watch on these parameters, divers can effectively manage their exposure to pressure and prevent conditions such as decompression sickness, which can occur if they ascend too quickly or spend too much time at depths beyond their no-decompression limits. Dive tables provide critical information on safe ascent rates based on the depth and duration of the dive, allowing divers to plan their dives accordingly and manage their decompression stops if required.

Additionally, continuous monitoring helps to ensure that divers do not run low on breathing gas, ensuring that they have a sufficient supply to safely complete their ascent. Failure to track these parameters could lead to significant risks associated with deep diving, emphasizing their importance in safe diving practices.
