## 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! ).
