How can the bends be prevented?
Don't dive too deep. Don't exceed no-decompression limits for the depth you dive to. (limits are available in any of the dive calculating tables) Ascend at a slow pace.
The minimum surface interval required to avoid stage decompression after a dive to 88ft for 18min followed by a dive to 78ft for 23min is?
2 hours 29minutes
What is The minimum surface interval required to avoid stage decompression after a dive to 88 ft for 18 minutes followed by a dive to 78 ft for 23 minutes is?
1 hour and 45 minutes
What is the minimum surface interval for a dive that is 70 feet for 29 minutes followed by a dive that is 50 feet for 39 minutes?
There is no minimum interval. A dive directly from 70 fsw for 29 minuts can immediately be followed to a dive to 50 fsw for 39 mins, and would be classed as a "Combined Dive" To calculate decompression from this Combined Dive, is by taking the depest depth, (70 fsw), and total time (68 mins), and decompress on an appropriate table. Using the USN repetitive dive times, this varies on the residual nitrogen remaining in solution.
What according to the Recreational Dive Planner is the no decompression limit for 18 metres or 60 ft?
NoD limit for 18m (or 60ft) is 60 minutes. Anything past 60 minutes you will owe decompression. Thats if you have enough air to be at that depth for that long.
Who gets decompression sickness?
Scuba divers who surface too quickly after a deep dive are prone to decompression sickness.
How much time does a scuba diver spend under water?
It depends on how deep the diver goes, and what air blend the diver is breathing. There are dive tables that state how long a diver can stay at a certain depth before requiring decompression. The basic recreational diver typically breathes either air or Nitrox. There are separate dives tables for air and Nitrox.
How long can a diver dive in 1 day?
It depends on many variables, such as the time the diver stays at a particular depth, the temperature, level of diver exertion, diver's physiology, etc, etc. Dive tables or a dive computer is used to calculate how long it is safe for the diver to stay submerged. The primary limitation on dive duration/depth during a day is how much Nitrogen the diver has absorbed into his or her tissues. Exceeding the safe limits can cause decompression illness. These limits are only rough guidelines however, as some people are at higher/lower risk for decompression illness based on their physiology, level of heath and fitness, and other factors.
What is the no-decompression limit for 60 feet or 18 meters?
The no-decompression limit for 60 feet (18 meters) is 55 minutes. This means that a diver can stay at this depth for up to 55 minutes without needing to perform a decompression stop on the way back to the surface.
What scuba depth is safe without a stop in case of emergency?
The recreational scuba dive depth limit is 130 feet. Keep in mind that skipping safety stops and avoiding decompression commitments is a function of depth AND time as well as each person's physiology individually. If you stay at almost any reasonable depth long enough you can push yourself into a decompression commitment. Normal divers on a single cylinder usually would run out of air before they build up enough of a nitrogen load but it is possible.
What is the first aid procedure for decompression illness?
1. Discontinue Dive 2.Seek Medical Attention 3. Consult a dive physician.
How deep do you have to go to get the bends?
The bends, or decompression sickness, can occur when ascending too quickly from a deep dive. It is more likely to occur in depths greater than 30 meters (100 feet). However, the exact depth at which it could happen varies depending on factors such as time spent at depth and rate of ascent.
