Q

When does decompression stop time commence?

A

For in-water D, on air, the time at the first D stop begins when the diver arrives at the stop and ends when the diver leaves. For all subsequent D stops, the time begins when the diver as left the previous stop and ends when the diver has left the next stop.

Q

When is a diver eligible for Surface-D?

A

Upon completing the 40fsw decompression stop. If a 40fsw stop is not required, the diver may ascend without stopping.

Q

For delays greater than 1 minute, and deeper than 50fsw.

A

Round up the delay time, add it to bottom time. Recompile the table and schedule. If no change, continue on as planned. If a change in schedule is required and the new schedule calls for a decompression stop deeper than the diver’s current depth perform any missed stops at the divers current depth.

Q

For SurDO2 dives done at altitude, are chamber stops adjusted for altitude?

A

No, this benefits the diver.

20
Q

What is the cabin pressure of most commercial flights?

A

8000ft.

21
Q

What surface interval is required before taking a commercial flight it the dive site is 8000ft or higher?

A

None.

22
Q

Hypoxia occurs if O2 falls below ____ ata on surface.

A

.16 (16%)

23
Q

What is the most prevalent of all abnormal gas problems in diving?

A

CO2 Toxicity (Hypercapnia)

24
Q

What are the symptoms of CNSO2 Toxicity?

A 
VENTID C
Vision blurred/tunneled
Ears- ringing or roaring
Nausea
Twitching/Tingling (usually the earliest onset symptom)
Irritability
Dizziness
-
Convulsions- most severe, may be sudden onset.
25
Q

What are the symptoms of Pulmonary O2 Toxicity?

A

CBD
Coughing
Burning
Dysnpea (shortness of breath)

26
Q

Hypothermia can occur when the core body temperature of the body drops below ___.

A

98 degrees.

27
Q

A neoprene wetsuit is required when diving water temperatures below ___ degrees.
VVDS is required when diving in water below ___ degrees.

A

40

28
Q

What are the 4 types of POIS commonly seen in diver related injuries?

A

Pneumothorax (Simple/Tension)
Mediastinal Emphysema
Subcutaneous Emphysema
Arterial Gas Embolism (This is the most serious)

29
Q

DCS Type 1

What is the most common symptom?

A

Joint pain is the most common symptom. Dull Ache is the key word.
Pain in the joint is present at rest but will not usually be made worse with movement.

30
Q

DCS Type II
Any ______ symptom that appears after 10 minutes on surface.
Any back or trunk pain that cannot clearly be related to physical injury that ________ or ____ an extremity. Must be assumed to be DCS Type II and treated.

A

Neurological symptoms

Radiates or encircles (girdle) and extremity.

31
Q

Breathing 100% O2 under pressure can be toxic at partial pressures of ___ to ___ ata

A

1.3 to 1.6

32
Q

BOYLE’S LAW

A

States that at a constant temperature, the absolute pressure and the volume of gas are inversely proportional.

33
Q

Charles/Gay-Lussac’s Law

A

States that at a constant pressure, the volume of a gas is directly proportional to the change in the absolute temperature.

34
Q

Dalton’s Law- The Law of Partial Pressure.

A

States that the total pressure exerted by a mixture of gases is equal to the sum of the pressures of each of the different gases making up the mixture, with each gas acting as if it alone was present and occupied the same volume.

35
Q

Henry’s Law: The Law of Absorption

A

The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of the gas.

Because a large percentage of the body is made up of water, Henry’s law simply states that as a diver descends deeper, more gas will dissolve in the body tissues. On ascent, the dissolved gas must be released.

36
Q

What is the minimum first aid equipment required on a dive side?

A

Communication equipment capable of reaching help
A fully stocked first aid kit
AED
Portable O2 with sufficient capacity to reach either the chamber or evacuation site

Means of immobilization (stretcher, backboard)
A means of extraction.

38
Q

What is classified as a as a Level II Recompression chamber?

A

A US Navy certified recompression chamber accessible within ONE HOUR of the casualty.

39
Q

What is classified as a Level 3 Recompression chamber?

A

A US Navy certified recompression chamber accessible within 6 hours of the casualty.

40
Q

Can a non-US Navy chamber be used to support operations?

A

Yes, if authorized in writing by the first flag officer in the chain of command. It must include a NAVSEA hazard analysis.

41
Q

If the Air Decompression Table does not list a repeat group designator for a dive, no repet dives deeper than 20fsw are permitted following this dive. The diver must have a ____ surface interval before diving deeper than 20fsw

A
