What are Recompression chambers used for?
|
Treatment of decompression sickness and AGE
Surface decompression Pressure tests |
|
|
What is Navy Recompressions Chamber Support level I?
|
USN certified chamber close enough to dive site to support a SUR-D with a surface interval of 5 minutes
|
|
|
What is Navy Recompressions Chamber Support level II?
|
USN certified chamber accessible within one hour
|
|
|
What is Navy Recompressions Chamber Support level III?
|
USN certified chamber accessible within six hours
|
|
|
During extreme circumstances when a chamber cannot be reached within six hours who can authorize the use of the nearest approved recompression chamber?
|
The CO
|
|
|
When can a non-Navy chamber accessible within one hour be used?
|
With approval in writing by the CNO
|
|
|
When can a non-Navy chamber accessible within six hours be used?
|
With approval in writing by the CO
|
|
|
When can a Navy Recompressions Chamber level I support be modified?
|
Based on space constraints at the site, the CO may authorize extension of the surface interval to a maximum of 7 minutes in accordance with Paragraphs 9-12.6 and 14-4.14.

|
What is an EEHS?
|
Emergency Evacuation Hyperbaric Stretcher
|
|
|
What is the EEHS used for?
|
The EEHS is a portable single lock allowing a patient to be administered oxygen at 60 feet while in transport to a recompression chamber.
|
|
|
What are the differences between the TRCS Mod 0, 1, and 2?
|
TRCS Mod 0 consists of two pressure chambers (the TRC and the TL). The two chambers are capable of being connected by means of a freely rotating NATO female flange coupling.
TRCS Mod 1 consists of just the TRC. TRCS Mod 2 is the TRCS Mod 0 which has had the 5000 psi upgrade ECP installed allowing it to be used with an Air Supply Rack Assembly (ASRA). |
|
|
What is the minimum air requirment for category D chamber primary air supply system?
|
Sufficient air to press the IL once and the OL twice to 165'.
(For TRCS, sufficient air to power CO2 scrubbers must be included) |
|
|
What is the minimum air requirment for category D chamber secondary air supply system?
|
Sufficient air to press the IL & OL once to 165' and enough air for 1 tender and 2 patients (when not on O2 ) to breathe air BIBS during 1 TT6A with
max extensions. |
|
|
Do not allow oxygen supply tanks to be depleted below what psig?
|
Do not allow oxygen supply tanks to be depleted below 100 psig.
|
|
|
T/F The actuating lever of the chamber gag valves shall be lock-wired in the closed position at all times, during both normal operations and when the chamber is secured.
|
False. The gag valves must be closed only in the event of relief valve failure during chamber operation. Valves are to be lock-wired in the open position with light wire that can be easily broken when required.
|
|
|
What is he basic rules for ventilation when air is being breathed?
|
When air is breathed, 2 acfm for each diver at rest and 4 acfm for each diver not at rest (i.e., a tender actively taking care of a patient).
|
|
|
What is he basic rules for ventilation when O2 is being breathed?
|
When O2 is breathed from the BIBS, 12.5 acfm for a diver at rest and 25 acfm for a diver who is not at rest.
|
|
|
When can you use air ventalation rates while breathing O2?
|
If a BIBS dump system or a closed circuit BIBS is used for O2 breathing, the ventilation rate for air breathing may be used.
|
|
|
When can ventalation rates be ajusted by the chamber Sup?
|
If portable or installed O2 and CO2 monitoring systems are
available, ventilation may be adjusted to maintain the O2 level below 25% and the CO2 level below 1.5% surface equivalent (sev). |
|
|
When should a USN chamber be pressure tested?
|
Every USN chamber shall be pressure tested when initially installed, at 2-year intervals, and after a major overhaul or repair.
|
|
|
What is the depth and length of stay for aU.S. Navy diver candidate pressure test?
|
Stay at 60 fsw for at least 10 minutes.
