Eric P. Kindwall, MD
As promised, this month we are diving into the published works of Dr. Eric P. Kindwall, widely referred to as the "Father of Hyperbaric Medicine." This week we are looking at the physics of diving and hyperbaric pressures. We invite you to take advantage of these free goodies...

Eric P. Kindwall, MD
Many refer to Dr. Kindwall at the "Father of Hyperbaric Medicine," and his contributions to hyperbaric medicine are legendary. Dr. Kindwall was born on January 17, 1934 and passed away on January 18, 2012. For this reason, we find it fitting to highlight his contributions to the field of hyperbaric medicine during the month of January. Dr. Kindwall

Clinic Marketing
Do you worry about not having a big enough patient load at your wound care and hyperbaric medicine clinic? Do you struggle with marketing due to low budget and not enough resources? You are not alone. We all know that maintaining a steady patient load is critical to keeping your wound care and hyperbaric clinic doors open and your staff (and yourse
Video #2 (Preventing Diver Fatalities Series): Preventing Dive Site Entrance and Boat Related Injuries

Scuba Diving Safety
Last week we released the first video in a new series on preventing diver fatalities. The second video in the series is now available! In the second video, we discuss two types of common surface related injuries to divers - those that occur during the entrance to a dive site, and boat related injuries. In this video you will learn: The most common

Scuba Diving Safety
This month we are discussing how to prevent diver fatalities. As part of that discussion, we are launching a free three-part video series. In the first video, we define diving medical fitness and answer common questions such as: Are diving physicals really necessary?Can they prevent diving accidents?Why is diving fitness necessary in recreational d

Increased Air Pressure and Improved Health

Better Healing with More Oxygen
A startling vindication of Cunningham’s assertion that a modest increase in pressure improves health has come from a study in Israel of patients with advanced lung disease, published in the journal Chest in 1996.17 The patients who were all receiving supplemental oxygen in Jerusalem were taken down to the Dead Sea to see if they would benefit from

Hypoxia vs. Carbon Dioxide in the Want of Oxygen

Better Healing with More Oxygen
If a gas not containing any oxygen is breathed, consciousness is rapidly lost with no increase whatever in the rate of breathing. Haldane had witnessed the effects first-hand down in the coal mines of South Wales: “Thus it is a common experience with miners going into an atmosphere of nearly pure fire damp [methane, CH4], or climbing up so that the
Drysuits 101

NOAA Diving Manual 5th Edition
Drysuits provide the greatest form of passive thermal protection for the diver. They are designed as one piece suits with a waterproof zipper for entering and exiting and have attached boots and seals at the diver’s wrists and neck to provide a dry internal environment. The suits are normally designed so a wide variety of insulating undergarments m
Basic Underwater Navigation
Basic Underwater Navigation
Jaclyn Mackey
NOAA Diving Manual 5th Edition
Basic underwater navigation by means of simple observation or use of a compass and depth gauge remains a fundamental and essential skill for all divers. For most short excursions, these are the only instruments needed. Even when using advanced navigation instruments, basic navigation skills provide an important backup. Much navigation can be accomp
