REPORT DATE: APR 2005
PAGINATION: 137 PAGES
REPORT NUMBER: NEDU-TR-05-04
MONITOR ACRONYM: XB
MONITOR SERIES: NAVSEA
DESCRIPTORS: *SEA RESCUE EQUIPMENT, OXYGEN, RESPIRATION, SUBMARINES, DECOMPRESSION, DIVER EQUIPMENT
IDENTIFIERS: SRDRS(SUBMARINE RESCUE AND DIVING RECOMPRESSION SYSTEM), HOTP(HYPERBARIC OXYGEN TREATMENT PACK) LIMITATIONCODE: 01 00 00
ABSTRACT: The objective of the present study was to develop and man-test oxygen-accelerated decompression schedules for repetitive sub-saturation air exposures by SRDRS PRM Operators and SDC Tenders in pressurized DISSUB rescue scenarios. A secondary objective was to evaluate the performance of the MBS 2000 Hyperbaric Oxygen Treatment Pack (HOTP) (Dive Systems International),2 a lightweight closed-circuit breathing apparatus planned to support oxygen breathing requirements of decompression schedules in actual DISSUB rescue scenarios. This study was undertaken under Naval Sea Systems Command Task Assignment 01-1 & as the final phase of development of oxygen-accelerated decompression procedures for personnel involved in DISSUB rescue scenarios.

TITLE: Evaluation of the KMS 48 Replacement Full Face Mask with the Emergency Breathing System for Use with MK 16 MOD 1 Underwater Breathing Apparatus
DESCRIPTIVE NOTE: Technical rept. Jan 2001-Dec 2002
PERSONAL AUTHORS: Hedricks, C. S. Stanek, S. J.
REPORT DATE: DEC 2002
PAGINATION: 20 PAGES
REPORT NUMBER: NEDU-TR-02-17
MONITOR ACRONYM: XB
MONITOR SERIES: NAVSEA
DESCRIPTORS: *BREATHING APPARATUS, *BREATHING MASKS, EMERGENCIES, HUMAN FACTORS ENGINEERING, RESPIRATION, DIVING
IDENTIFIERS: UBA(UNDERWATER BREATHING APPARATUS), EBS(EMERGENCY BREATHING SYSTEM), FFM(FULL FACE MASK) LIMITATIONCODE: 01 00 00
ABSTRACT: Navy Experimental Diving Unit (NEDU) was tasked by references (1) and (2) to test and evaluate the MK 16 MOD 1 underwater breathing apparatus (UBA) for use as an emergency breathing system (EBS) in conjunction with the KMS 48 full face mask (FFM). Testing was designed to assess the abilities of the KMS 48 FFM and the MK 16 MOD 1 to perform as an EBS during unmanned and manned open water dives to the maximum operational working depths for each breathing medium: 190 feet of seawater (fsw) [58.2 meters of seawater (msw)] with nitrox (N2O2), and 300 fsw (91.9 msw) with heliox (HeO2).

FIELDS GROUPS: PROTECTIVE EQUIPMENT
CORPORATE AUTHOR: NAVY EXPERIMENTAL DIVING UNIT PANAMA CITY FL
TITLE: Evaluation of the Joint Service General Purpose Mask, XM50
DESCRIPTIVE NOTE: Technical rept. Jun-Jul 2004
PERSONAL AUTHORS: Hyde, Dale Garigan, Meave Johnson, Dennis
REPORT DATE: JUL 2005
PAGINATION: 74 PAGES
REPORT NUMBER: NEDU-TR-05-10
MONITOR ACRONYM: XA
MONITOR SERIES: ECBC
DESCRIPTORS: *PROTECTIVE MASKS, BIOLOGICAL AGENTS, STRESS(PHYSIOLOGY), AMMONIA, PERSPIRATION, FOG, CHEMICAL AGENTS, ACCUMULATION
IDENTIFIERS: JSGPM(JOINT SERVICE GENERAL PURPOSE MASK), XM50 LIMITATIONCODE: 01 00 00
ABSTRACT: The Joint Service General Purpose Mask (JSGPM) is the next generation chemical protective mask intended to replace the MCU-2 and M-40 series masks. Developmental testing and user assessment of the XM5O, a variant of the JSGPM, indicated that the XM5O lacked sufficient fogging mitigation1 and sweat reduction capabilities. Lens fogging and sweat accumulation in the mask degrade user confidence, impose a physiological burden upon the user, and can seriously degrade operational effectiveness. These performance shortcomings resulted in joint service concern,2 and design changes to the mask were made. In 2003, a field evaluation3 indicated that the sweat reduction issues had been resolved, but the evaluation was limited and did not challenge the XM5O's ability to mitigate fogging.

TITLE: Carbon Dioxide Washout of an Emergency Breathing System Mask Modified for Use in the Advanced Seal Delivery System (ASDS) Trainer
DESCRIPTIVE NOTE: Technical rept.
PERSONAL AUTHORS: Carlson, N. A. Warkander, D.
REPORT DATE: AUG 2005
PAGINATION: 17 PAGES
REPORT NUMBER: NEDU-TR-05-13
MONITOR ACRONYM: XB
MONITOR SERIES: NAVSPECWARCO
DESCRIPTORS: *BREATHING MASKS, SLOTS, CARBON DIOXIDE, RESPIRATION, HOSES, EXHALATION, BREATHING APPARATUS, INHALATION
IDENTIFIERS: ASDS(ADVANCED SEAL DELIVERY SYSTEM), EBS(EMERGENCY BREATHING SYSTEM) LIMITATIONCODE: 01 00 00
ABSTRACT: A modified emergency Breathing System full face mask was evaluated for use in the Advanced SEAL Delivery System trainer. The mask contained an oral-nasal cup and two spiral-wound plastic hoses on its inhalation and exhalation openings. Each hose was six feet long with an inside diameter of 1.25 inches and had six rectangular slots cut through the hose wall. The slots were approximately eight inches from one end of each hose. Testing was conducted in an unpressurized hyperbaric chamber that was well ventilated with air. Carbon dioxide (CO2) washout volume - averaged inspired CO2 - was calculated at a respiratory minute ventilation of 22.5 liters per minute (1.min(exp -1). The mask was ventilated with a mechanical breathing simulator. One hundred per cent CO2 was injected at 0.9 1.min(exp -2) into the breathing loop. Mean CO2 washout was determined for two configurations: normal, with both hoses positioned so that the slotted ends are near the mask; and reversed exhaust, with inhalation hose positioned with its slots near the mask and exhalation hose positioned with the slots away from the mask. By our normalizing for the actual end-tidal CO2 level, the volume-averaged CO2 in the normal configuration was 0.71% and 0.75% with the exhaust reversed. Carbon dioxide washout of the modified emergency breathing system mask with exhaust hose in either configuration is acceptable for use in the ASDS trainer.
