1. Return to Diving and Hyperbarics Post-COVID-19

   COVID-19 left lasting questions for divers: lung scarring, cardiac inflammation, impaired gas exchange. When is it safe to go back in the water, and under what conditions? This paper reviews the return-to-dive criteria after SARS-CoV-2 infection, covering both recreational and professional diving alongside hyperbaric oxygen therapy considerations.

2. Real-time heart rate variability analysis as a means of hypercapnia detection

   Carbon dioxide builds up silently in a closed-circuit diver, and by the time symptoms arrive it can be too late. This study asked whether the heartbeat itself gives earlier warning. In fifteen subjects breathing progressively higher CO2, the beat-to-beat pattern grew measurably more erratic before any symptoms appeared, and returned to baseline on clean air, a signal in under two minutes. It establishes that the signal exists. It does not establish that a wearable using it would hold up in cold water, under exertion, with a working diver's task loading.

3. Maladies Specific to Technical and Rebreather Divers

   Technical divers and rebreather divers face failure modes that open-circuit recreational divers do not: hypercapnia from scrubber failure, hyperoxia from wrong-gas switches, hypoxia from loop volume loss, and isobaric counter-diffusion from helium transitions. This chapter catalogs those maladies and their field recognition.

4. Ketogenic Diet and Ketogenic Supplementation for Central Nervous System Oxygen Toxicity

   The companion chapter to the 2014 feasibility study. Where that paper tested whether divers could hold ketosis during real dives, this chapter reviews the mechanism: how a ketogenic state may raise the seizure threshold against central nervous system oxygen toxicity, and what the animal and human evidence says so far.

5. Ketogenic diet for high partial pressure oxygen diving

   Breathing oxygen at high pressure can trigger seizures. Ketogenic diets reduce seizures in epilepsy, so could divers tolerate one during real operations? Three experienced rebreather divers in Hawaii held ketosis through normal diving profiles with no seizures, no signs of oxygen toxicity, and no interference with the mission. Three subjects is a feasibility study. It shows the approach is testable. It does not show that it works.

6. Could the U.S. Navy benefit from technical diving techniques?

   An abstract presented at the Undersea and Hyperbaric Medical Society meeting, asking whether the equipment and gas-management practices developed by civilian technical divers could improve Navy diving operations. The question was pointed: Navy diving gear had not changed substantially in decades while the civilian technical community had moved ahead.
