"If the ascent rate is too fast, the pressure drops rapidly, and the dissolved nitrogen will form bubbles in the body, like opening a bottle of soda, blocking blood vessels, causing severe pain, or even death."
He wasn't scared by these terrible consequences; instead, he developed a strong interest in the working principles of the "dive watch."
Immediately, he went online to look up the technical documentation of the Shearwater Teric watch he purchased, which uses the "Bühlmann ZHL-16C gradient factor algorithm."
On the screen, complex mathematical formulas and body tissue models turned into a vivid dynamic landscape in his eyes.
He understood how the electronic watch calculates the nitrogen saturation of 16 different "tissue compartments" in his body in real-time based on depth and time.
And it planned for him a safe no-decompression stop time and ascent rate, solving the "physical" level of danger.
