Rebreather' Helps Navy Divers Beneath the Waves 31 May 2018, by Warren Duffie Jr
Deep breath: New 'rebreather' helps navy divers beneath the waves 31 May 2018, by Warren Duffie Jr. Panama City. The technology is sponsored by the Office of Naval Research Global (ONR Global) TechSolutions program. TechSolutions is ONR Global's rapid- response science and technology program that develops prototype technologies to address problems voiced by Sailors and Marines, usually within 12 months. "This rebreather system is an awesome opportunity to enhance the capabilities of Navy divers and accelerate their deployments," said ONR Command Master Chief Matt Matteson, who heads up TechSolutions. A US Navy diver gives the okay sign following his dive using the Office of Naval Research Global Navy diving missions include underwater rescues, TechSolutions-sponsored MK29 Mixed Gas Rebreather explosive ordnance disposal, ship hull system, which was developed at the Naval Surface maintenance, recovery of sunken equipment, and Warfare Center, Panama City Division. The new system salvage of vessels and aircraft. will conserve helium, which is a valuable natural resource, accelerate the deployment of Navy divers, and increase safety.

Below 150 feet, however, nitrogen becomes toxic—leading to nitrogen narcosis, a drowsy state that can dull mental sharpness severely and jeopardize safe The muscular U.S. Navy diver hoisted a 60-pound return to the surface. life-support regulator onto his back, then donned a 30-pound metal helmet. The solution is to replace nitrogen with helium. However, helium is expensive and hard to obtain Fellow divers connected his diving suit to an because of recent worldwide shortages. -

HARBOR BRANCH FOUNDATION TECHNICAL REPORT No.21 , HISTORY ·One of the first written records of man's ability to work underwater is found in the writings of Herodotus in the 5th Century B.C. He tells of a diver named Scyllis who worked to recover sunken treasure for King Xerxes. There are many other accounts of divers working underwater by holding their breath for two to three minutes but it was not until 1500-1800 A.D. that any significant advancements were made which could be attributed to present day diving technology. During the period after 1500, a device called a diving bell came into the forefront as a practical tool to explore the underwater world. The device was called a bell because it resembled a typical church bell of the times. The first account of such equipment being used was in 1531. Bells did not advance much until the 1680's when an adventurer named William Phipps from Massachusetts supplied air toa bell by lowering inverted, weighted buckets of air to the divers. The famed astronomer, Edmund Halley, also developed a bell and demonstrated his system in 1690. Other inventions by various people were developed but were all like the first diving bells limited by the fact that air could not oe continuously supplied to the divers. It was not until the turn of the 19th Century that a hand oper ated air pump was developed which could deliver a continuous supply of air. -

Scuba Diving History
Scuba diving history Scuba history from a diving bell developed by Guglielmo de Loreno in 1535 up to John Bennett’s dive in the Philippines to amazing 308 meter in 2001 and much more… Humans have been diving since man was required to collect food from the sea. The need for air and protection under water was obvious. Let us find out how mankind conquered the sea in the quest to discover the beauty of the under water world. 1535 – A diving bell was developed by Guglielmo de Loreno. 1650 – Guericke developed the first air pump. 1667 – Robert Boyle observes the decompression sickness or “the bends”. After decompression of a snake he noticed gas bubbles in the eyes of a snake. 1691 – Another diving bell a weighted barrels, connected with an air pipe to the surface, was patented by Edmund Halley. 1715 – John Lethbridge built an underwater cylinder that was supplied via an air pipe from the surface with compressed air. To prevent the water from entering the cylinder, greased leather connections were integrated at the cylinder for the operators arms. 1776 – The first submarine was used for a military attack. 1826 – Charles Anthony and John Deane patented a helmet for fire fighters. This helmet was used for diving too. This first version was not fitted to the diving suit. The helmet was attached to the body of the diver with straps and air was supplied from the surfa 1837 – Augustus Siebe sealed the diving helmet of the Deane brothers’ to a watertight diving suit and became the standard for many dive expeditions. -

This is a unique and comprehensive summary of world wide development in this field. It is probably not realised what a vital part closed circuit breathing apparatus played in World War II. Apart from escapes from damaged and sunken submarines by means of the DSEA, and the special attacks on ships by human torpedoes and X-craft, including the mortal damage to the "Tirpitz", an important part of the invasion forces were the landing craft obstruction clearance units. These were special teams of frogmen in oxygen breathing sets who placed demolition charges on the formidable underwater obstructions along the north coast of France. -

DCS Treatment Updates
Treatment of Decompression Sickness Operational Update – May 2001 Aspirin is NO LONGER USED in the treatment of DCS. Reasons: ASA administration has never been shown to help prevent or treat bubbles DCS may induce microhemorrhages in tissues. ASA slows clotting. Hard to determine if symptom decrease is due to HBO treatment table or ASA This may be a critical treatment decision factor if using TT-5 Hyperbaric Oxygen is the only necessary and sufficient drug for DCS Employment of 100% O2 by tight fitting aviators mask during transportation to HBO chamber For mild to moderate symptoms with no CNS or spinal neurological involvement: Use cycles of 50 min of 100% O2, followed by a 10 min air break, instead of continuous O2 Reasons: Air breaks minimize likelihood of pulmonary and CNS O2 toxicity Rehydrate & feed patient orally during air break May obviate need for IV rehydration Bathroom privileges during air breaks You ever wear a tight fitting oxygen mask for 3 hours straight? Patient can call spouse – “I’ll be home late tonight.” Air breaks are NOT used during SLO2 (Surface Oxygen) treatment protocols For severe symptoms, chokes, shock, CNS, spinal, or worsening Sx despite O2 therapy: Use continuous O2 therapy with IV rehydration (0.9% Saline or Ringers Lactate, NOT D5W) In general, do not pass up an otherwise acceptable monoplace facility (with BIBS) in favor of a multiplace facility for treatment of severe DCS or AGE if the additional travel time to the multiplace exceeds 30 minutes. Less than 30 minutes difference, or mild to moderate symptoms, requires the sending physician to consider risks and benefits of treatment delay versus multiplace advantages. -

KML Education & Research Boating & Snorkeling (Free diving) Agreement **Please review with all members of your group As Principal Investigator (PI)/Group Leader from ____________________________________, students in my care understand that all forms of ocean recreation activities, including but not limited to snorkeling (free diving) and boating (collectively the “Activities”) have inherent risks and dangers associated with them. Persons not in good physical condition, pregnant, with heart conditions, asthma (exercise or cold‐induced), back or neck injuries, open wounds and recent surgeries should not participate in the Activities. _____1. They agree that if they participate with an in‐water snorkeling activity that they can swim and have the skills to snorkel in the open ocean with no assistance. If they cannot swim they agree to remain on the boat/vessel at all times. They also agree that they will not expect the Released Parties to teach them how to swim or snorkel and that prior to the activity they will have the skills necessary to participate without assistance. It is required that the PI or Group Leader possess at least minimal snorkel skills. (Recommended minimal skills supplied upon request) ______2. THEY UNDERSTAND THAT THERE ARE INHERENT RISKS INVOLVED WITH SNORKELING AND BOATING, included but not limited to equipment failure, perils of the sea, harm caused by marine creatures (including bites), acts of fellow participants, entering and exiting the water, boarding or disembarking boats, and activities on the docks and THEY HEREBY ASSUME SUCH RISKS. ______3. They are physically fit to swim and participate in the Activities and understand that they can be physically strenuous activities and that they will be exerting themselves during the Activities.
