What is US Navy Table 6?

What is the max ppO2 allowed in treatment gas?
Technical divers often use a maximum of 1.6 ATA partial pressure of oxygen (ppO2) for a safe oxygen limit underwater during planned decompression, whereas recreational divers usually prefer a more conservative limit of 1.4 ATA.
What are the symptoms of decompression sickness?
(Decompression Illness; Caisson Disease; The Bends) Symptoms can include fatigue and pain in muscles and joints. In the more severe type, symptoms may be similar to those of stroke or can include numbness, tingling, arm or leg weakness, unsteadiness, vertigo (spinning), difficulty breathing, and chest pain.
What body system does decompression sickness affect?
Type I decompression sickness tends to be mild and affects primarily the joints, skin, and lymphatic vessels. Type II decompression sickness, which may be life-threatening, often affects vital organ systems, including the brain and spinal cord, the respiratory system, and the circulatory system.
How many dives can I do a day?
For recreational divers, a typical limit is 4-5 dives per day as long as you follow dive tables or use a computer to track. For shallower depths, you will need to refer to dive tables to be able to determine how many dives you can safely do in a day and how long those dives can last.

What is decompression illness?
Decompression sickness, also called generalized barotrauma or the bends, refers to injuries caused by a rapid decrease in the pressure that surrounds you, of either air or water. It occurs most commonly in scuba or deep-sea divers, although it also can occur during high-altitude or unpressurized air travel.
Can you take Dramamine while diving?
Take antiemetic medication; some divers find taking Bonine or Dramamine the night before a dive to be more effective than taking it the morning of. Check the medication’s guidelines to see how long it takes to take effect and how long it lasts.

Can you fart while diving?
Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.
How to read dive tables?
Read horizontally to the interval in which the diver’s surface interval lies . Next, read vertically downward to Cthe new repetitive group designation . Continue downward in this same column to the row that represents the depth of the repetitive dive .
What are diving tables?
Often dive tables. a numerical table used by scuba divers to determine time limits of dives, according to depth, as well as possible decompression delays during ascent and requisite surface intervals between dives.
What is the US Navy base?
A naval base, navy base, or military port is a military base, where warships and naval ships are docked when they have no mission at sea or want to restock. Usually ships may also perform some minor repairs.
