Carboxy-Hemoglobin Peak Level Estimator: (18 Oct 00) So the patient comes to you, having been pulled from the burning building 2 hours ago, with a veinous CO-Hgb level of 20. Of course they've been on oxygen by non-rebreather for 90 minutes - - so HOW can you estimate the peak CO-Hgb level at the scene of the fire?? This Excel spreadsheet will let you do just that!!

Oxygen Decompression Tables for Inside Observers: (25 Jan 2K) Dry diving is physiologically different than wet diving, as tissue bed perfusion, among other things, is different when buoyed up in water than when under the differential effects of 1G in the dry chamber. This fact was noted in 1963 when Dr. Bruce Bassett developed the USAF Diving Tables in an attempt to decrease the DCS hit rate in dry dive IOs. The attached tables were derived from Nobendem at depths of 30, 45, 60, 165 FSW with Safety Enhancements of 55 and 65. Repetitive Group Indicators have been calculated which are compatible with the USN table 7-4. (in Acrobat format).

Oxygen Deco Tables for IOs during Fire Suppression Equipment Tests: (25 Jan 2K) Every 6 months, multiplace chamber units should check their water deluge fire extinguisher system. This involves a descent to 165 for 2-3 min at depth, an ascent to 60 FSW where the test is repeated, followed by final ascent and Oxygen decompression. The attached tables specify Nobendem derived Deco Tables based on Time At Depth for each segment, and include the Repet Group for the dive. (in Acrobat format).

Nobendem: (4 Mar 02 update - Fixed glitch in Segment 12 of Long Dive B) An Air-Nitrox decompression profile calculator for use at sea-level and at altitudes up to 20K. Uses a 10 tissue compartment model. Complete documentation and theoretical discussion. Spreadsheet Calculator requires Microsoft Excel 95 or better. (Zipped file - contains nobendem.xls, nobendem.pdf, readme.txt)

Smooth Ride: (30 Sep 98 update) Wound Care Treatment Table Descent and Ascent Profile (45 FSW) based on a constant differential volume change to decrease the likelihood of barotrauma (in Acrobat format). Contains follow-up statistical analysis.

Smooth Ride Profiles for Monoplace Chambers: (30 Apr 99) Treatment Table Descent and Ascent Profiles (to 33, 45, 60, 66 FSW) based on a constant differential volume change. Decreases the likelihood of barotrauma for your patients (in Acrobat format).

Chamber Dive Profile Air Requirements Calculator: Want to know how many cubic feet of air your planned dive profile will use? Does your accumulator have enough air stored to make the dive? Use this Excel Spreadsheet calculator to find out (zipped with PDF TT-6 example)!

SCUBA Dive Air Requirements Calculator (20 Jul 99): Want to know if your SCUBA tanks hold enough air to make that dive? Use this Excel Spreadsheet calculator to find out (zipped with AL-80 {really only holds 74.6 at 3000 PSI} to 120 for 18 PDF example)! Jul 99 adds altitude capability.
