representation of just how close you are to the no decompression limit with a
yellow Caution (C.Z.) Zone that allows you to make a decision regarding safety
stop duration or necessity. The Tissue Loading Bar Graph™ has been granted
U.S. Patent No. 4,882,687.
The Tissue Loading Bar Graph™ also assists you with managing decompres-
sion (explained later) by filling a large red 'ceiling stop required' segment.
Oxygen Accumulation (O2) Bar Graph
NOTE: Displays associated with oxygen and the O2 bar graph
will only appear if FO2 has been set at a value other than 'Air'.
The Oxygen Accumulation (O2) Bar Graph (Fig. 5) represents oxygen loading,
your relative oxygen tolerance dosage (OTU), showing the maximum of either
per dive accumulated oxygen, or 24 hour period accumulated oxygen. As your
exposure (accumulation of oxygen) increases during the dive, segments will
add to the bar graph starting in the lower right portion of the screen. As oxy-
gen loading decreases, the bar graph will begin to recede, indicating that addi-
tional exposure (accumulation) is allowed for that dive, and 24 hour period.
The O2 bar graph also assists you with managing high partial pressure of oxy-
gen (PO2) by flashing the large red Danger zone segment as a warning when
the level of PO2 exceeds the maximum allowed limit of 1.60 ATA.
