How Accidents Happen In The Hyperbaric Environment

Hyperbaric Facility Safety

For some accidents there is a "smoking gun". However, most accidents are caused by a combination of factors, each of which contributes in some manner. Often these factors accumulate over some period of time preceeding the accident. This chapter addresses the factors that foster conditions under which accidents are more likely to happen and discusses some of the steps to be taken to avoid them. Also included is a case history illustrating several of the factors.

An Unexpected Odyssey

We had entered a dense fog bank! I had a rather helpless feeling, as a boy of 18, guiding 2,300 tons of steel into the unknown at ten knots, with no way of notifying anyone. Fortunately after a few minutes, which seemed like an eternity, the mate returned to the bridge. Flipping on the radar on the port side of the wheelhouse, he remarked, "Looks like we've got a bit of thick weather." He stepped out on the bridge wing and blew his police whistle to alert Kalle Holm, my watch partner. Kalle immediately stuck his head over the top of the bridge ladder and was ordered to the bow to stand lookout. 

When the radar had warmed up, the mate said, "Looks like we've got another ship out there. Give her five degrees starboard."

I heard the ship's bell strike three times . . . It was the other ship's bow lookout and we were directly in his path! I saw a huge bow as high as our wheelhouse loom out of the fog!"

The above is just one of the hair-raising experiences described by Dr. Kindwall as he writes of his time in the merchant marines, and via Yale and Harvard, running a safe-house for the CIA, submarine school, patrol on an early Polaris nuclear submarine, and work with "sandhogs" in compressed air tunnel construction.

What can be used to disinfect acrylic chambers?

What-can-be-used-to-disinfect-acrylic-chambers

In many hospitals that treat hyperbaric patients, the task at hand is getting the infection control policy makers to understand that many of the hospital-based disinfectants cannot safely be used on the acrylics of both multiplace and monoplace chambers. The most-asked question is, “What can now be used to disinfect acrylic chambers?” With the increasing concern over nosocomial infections and the possible effect they have on patient outcomes, keeping the hyperbaric chamber infection free is a major concern for all. On page 274 of Hyperbaric Facility Safety: A Practical Guide, 2nd Edition you can find the most current list of disinfectants that can used on the acrylic portion on both multiplace and monoplace chambers, and the products that have been identified acceptable for use on acrylic hyperbaric chambers for infection control.

Gas Gangrene: Antiobiotics vs. HBO2

Although the incidence of clostridial myonecrosis infections has dropped precipitously in recent decades, it always remins a threat in injuries where contamination and severe tissue disruption have occurred. The decreased incidence of clostridial myonecrosis is attributed to the increased diligence of clinicians in preventing clostridial organisms from proliferating. This has been realized through the immediate initiation of antibiotics in open injuries, the use of prophylactic antibiotics in surveries, and the appreciation of the value of meticulous debridements in injuries where amssive contamination (e.g., farm-related), severe trauma to tissues (e.g., combat-related), and tissue death from hypoxia have occurred.
