Dive Computers: Understanding Conservatism and Gradient Factors
[youtube v=”fklZdcOdehM”]
In this article, we will explore the concepts of conservatism and gradient factors in dive computers. As a seasoned tech diver instructor and underwater explorer, Jill Heinerth emphasizes the importance of these factors in planning safe and successful dives. Dive computers play a crucial role in helping divers push the bounds of human endurance and explore uncharted territory underwater.
Conservatism Levels: Adjusting Personal Risk Factors
Dive computers offer the diver the opportunity to adjust personal risk factors by selecting different levels of conservatism. These personal risk factors can include age, injuries, illnesses, diving practices, thermal considerations, activity level, sea state, and buoyancy control. By understanding and adjusting conservatism settings, divers can enhance their safety underwater.
Recreational divers have the option to select a more conservative level, which allows them to leave the water sooner due to reduced no decompression limits. On the other hand, technical divers who choose a more conservative setting can stay in the water longer during decompression. These settings are often represented with plus one or plus two for more conservative and minus one or minus two for less conservative. It’s important to consult your computer’s manual to learn how to adjust conservatism factors according to your preferences.
Jill Heinerth highlights the significance of understanding and adjusting conservatism settings, as personal factors should not be overlooked. She simplifies the description of different strategies to make it accessible to divers without a physics degree.
“Personal factors should not be overlooked, and yet few divers know how to adjust those factors in a way that positively impacts their safety.”
Gradient Factors: Modifying Mathematical Models
Gradient factors are another important aspect to consider when using dive computers. One common mathematical model used in dive computers is the Bullman model, which can be modified using gradient factors. However, it’s important to note that not all Bullman algorithms are identical, as manufacturers may modify the math or use different tissue compartments.
In simple terms, gradient factors alter the math in a way that changes the diver’s decompression profile. There are two numbers used to describe a gradient factor, separated by a forward slash. For example, 30/70 or 20/80 are examples of gradient factors. The first number, known as the gradient factor low, determines the depth of the first stop or the deepest stop. The second number, known as the gradient factor high, offers the overall conservatism.
“The first number indicates how close to super saturation you want to be for the controlling tissue compartment before you generate a decompression stop. The second number offers the overall conservatism.”
Jill Heinerth highlights the importance of understanding these numbers as percentages and how they impact the divers’ decompression profile. Lower numbers generate deeper stops, while higher numbers provide additional conservatism. It’s important to find the right balance that ensures safety without unnecessary risks.
Conflicting Information and Research
There is conflicting information when it comes to deep stops and their efficiency in preventing decompression illness. Social media and anecdotal reports have led to much misinformation within the diving community. Recent research indicates that arbitrary deep stops may even increase neurological hits.
Professor David Doolet, in his article “Gradient Factors in a Post-Deep Stop World,” argues that deep stops are not necessarily more efficient and suggests that safer profiles can be achieved through other means.
“Since about 2005, evidence has been accumulating from comparative decompression trials that show deep stops are not more efficient and possibly less efficient than shallow stops.”
He recommends using gradient factors of 70/85 for his own dives, but acknowledges that there is still much to study and learn in this area.
Adaptable Algorithms: Real-Time Feedback
Algorithms such as Cento’s fused RGBM offer real-time feedback and can adapt to a diver’s specific diving behaviors. These algorithms take into consideration factors such as multi-day diving, reverse profiles, rapid ascent, and individual risk factors. Based on these practices, the algorithm generates reduced no-stop times, longer decompression stops, or additional safety stops.
This adaptive algorithm ensures divers are provided with tailored decompression schedules that align with their specific diving circumstances. For recreational divers engaging in simpler dives, the algorithm remains invisible and does not require any modification. However, as divers transition into riskier, deeper, longer, or more frequent dives, the algorithm shifts to a more technical mode.
“Stepped decompression stops made sense when we were using diving tables, but modern algorithms such as Cento fused better represent the slow gradual release of pressure from a continuous ascent.”
Centos unique feature displays the decompression ceiling and the “deco window” to guide the diver during the ascent. Upward arrows indicate on-gassing, while downward arrows prompt the divers to descend back to the sealing zone if the ceiling depth is violated.
Personal Responsibility and Individual Risk Assessment
Jill Heinerth emphasizes the importance of personal responsibility and individual risk assessment in diving. While it may be tempting to try to match diving profiles with others or select algorithms based on someone else’s computer, it is essential to prioritize personal safety and risk factors.
“Regardless of the strategy or algorithm you choose for calculating your decompression, please remind yourself that it should be a reflection of personal risk assessment.”
Each diver’s profile, gases, behaviors, and risk factors are unique, making it impossible to align completely with another diver. Therefore, it is crucial to make choices that protect you from decompression illness in the short term and potential long-term damage.
Conclusion
Understanding conservatism and gradient factors is vital for divers to plan safe and successful dives. Dive computers offer the opportunity to adjust personal risk factors and tailor decompression profiles based on individual preferences. It’s important to consult your computer’s manual, study the different strategies, and ensure that your diving practices align with your personal risk assessment.
Remember, personal responsibility and informed decision-making are key to ensuring a lifetime of safe and enjoyable diving experiences.
