What are gradient factors?
The Gradient Factor defines the amount of inert gas supersaturation in leading tissue compartment. Thus, GF 0% means that there is no supersaturation occurring and inert gas partial pressure equals ambient pressure in leading compartment (Note: The leading TC is not necessarily the fastest TC!).
What is a conservative gradient factor?
One conservatism construct, gradient factors, stands as a method that is fairly easy to understand, easy to quantify, and relatively free of descriptive bias. Gradient factors, in the simplest sense, allow exposure limits to be adjusted to become a fraction of other limits.
What was the initial problem that dive rite was experiencing?
Like other companies, Dive Rite became frustrated by expensive, wasteful traditional marketing and advertising methods. They needed a lifeboat. Dive Rite brand, its history, and the quality of the gear because Dive Rite had stopped telling its story AND was unable to effectively represent its products.”
What are gradient factors in diving?
Developed by Erik Baker, gradient factors allow divers to adjust exposure limits to become fractions of another limit. Gradient factors are commonly used with the Bühlmann algorithm, a well-researched set of decompression procedures for which the underlying source code was openly released to the community.
What is the primary cause of decompression sickness?
Decompression sickness (DCS) occurs when dissolved gasses (usually nitrogen or helium, used in mixed gas diving) exit solution and form bubbles inside the body on depressurization.
Who owns Dive Rite?
After being with the company from the start, in 1997 Lamar bought Dive Rite from his friend and co-founder Mark Leonard.
What causes decompression sickness?
What is residual nitrogen?
Residual Nitrogen Time (RNT) This is the amount of time you must consider as already having been spent at a given depth for a planned repetitive dive. This time is based on the residual nitrogen remaining in your body from a previous dive or dives.
What does BC stand for in scuba diving?
BCD (Buoyancy Compensating Device) or Buoyancy Compensator (BC)
What is the gradient factor of Buhlmann m-value?
First, the gradient factor formula tells us that at a GF=1.0, you are at Buhlmann’s M-value. Therefore, staying at or below GF=1.0 seems important. Second, it tells us that when our tissue compartment pressure just reaches ambient pressure, then the GF=0.0.
What are gradient factors and how do they work?
More sickness occurs at and above the pressures represented by M-values and less sickness occurs when divers never reach Buhlmann’s M-values. Gradient factors (GFs) were invented to let the diver choose how fast, and how close, their TCs get to Buhlmann’s M-values. Gradient factors are calculated as follows: What does this formula tell us?
What is Buhlmann’s m-value?
Buhlmann answered that question by coming up with an “M-value”. Basically, an M-value is a maximum pressure value (different for each depth and tissue compartment) that tells you, if you exceed that value, Buhlmann thinks you’re crazy and believes you’re about to get bent.
What is the gradient factor of the leading tissue compartment?
The Gradient Factor defines the amount of inert gas supersaturation in leading tissue compartment. Thus, GF 0% means that there is no supersaturation occurring and inert gas partial pressure equals ambient pressure in leading compartment ( Note: The leading TC is not necessarily the fastest TC! ).
