Pelagian approach to Instant Cell Validation

Pelagian approach to Instant Cell Validation- A pro active way to really find out if the sensors make sense is to have the diluent FgO2 x ambient pressure pre calculated in 5 m increments on your wrist slate or wet notes. Then go to the nearest depth and exhale half a breath from your nose and inhale slowly. If you inhale very slow for 10 seconds you will get a very accurate reading.

Active Sensor Validation (ASV)

Active Sensor Validation-allow the manual  injection of diluent gas directly on the oxygen sensors at any point during a dive. This  feature served two functions: it purged any condensation that might have accumulated  on the sensors (thereby restoring function to sensors blocked by a film of water on the  sensing membrane) and, more importantly, it exposed the oxygen sensors to a known  fraction of oxygen.

An underwater physiologist with deep roots in the commercial and scientific diving industries, in the late 1980’s he suddenly found himself without a challenge. “They had pretty much learned how to do what they needed to and so weren’t doing much in the way of physiological studies,” says Hamilton.

World Record Rebreather Dive Oct 28th 2004 (Author: Dave Shaw)

If you’re frequent reader, you’d noticed that we review events occurred at the diving community. Because history should be studied and comprehend, for two main reasons: first, “learn from it” and secondly, “to know where we came from”. Without further ado, lets get into this wonderful article lost in time over the net (printed as […]

Then and Now: How learning to dive has changed

Do you want to learn Scuba Diving, read this first: Today’s instructors are teaching in a different academic environment than past years. More than 25 years ago the diving community was led by oils companies, a handful of few small civil communities and Navy. The oil companies invested a lot in researched, in developing technical […]
