**Safe PPO2 Control Deep Life**

Maximum Operating Depth (MOD) is the maximum safe depth at which a given nitrox mixture can be used. MOD depends on the allowed partial pressure of oxygen, which is related to exposure time and the acceptable risk assumed for central nervous system oxygen toxicity.... With super-nitrox - delivering the optimum oxygen-rich mix at every depth throughout the dive and an increasingly super oxygen-rich mix at deco depths, the Inspiration gets you out of the water much much quicker than the open circuit guys.

**How much longer does Nitrox last on average? scuba - reddit**

15/08/2009 · PPO2 depth = PPO2 surface * pressure in bars Now pressure in bars = 1+ (depth in meters/10), so depth = 0 means pressure =1 bar, depth =10m means pressure is 2 bars. This is the same calculation you do in your head if you try to find out the pressure at your given depth or vice versa.... Fitness of persons carrying out the work. Do all divers have a current (within last 12 months) certificate of medical fitness to dive? Does each diver have a copy? Competency. Does each diver, standby diver and dive supervisor hold a current certificate indicating training to a level equal to or exceeding that specified in AS2815 parts 1-4 as appropriate (e.g. an appropriate ADAS diver

10/12/2018 · As for the current diving situation, gas switch cues will be given as soon one is above the configured change depth of a gas and the ppO2 of the gas is not higher than the configured ppO2 max or max deco, dependent if in deco or not. how to take great portrait photos 15/01/2004 · It is generally felt that a PPO2 of 1.4 (roughly the equivalent of breathing air at 187') is the safe working maximum PPO2 you should expose yourself to, and a PPO2 of 1.6 is the safe MAXIMUM PPO2 you should expose yourself to (roughly 218' depth), before oxygen toxicity becomes a concern. At these depths however, nitrogen narcosis is probably the limiting factor.

**High risk diving work compliance checklist**

130 feet is roughly equal to 40 meters of depth where the atmospheric pressure is 5 times that of the surface. The tank that you carry is compressed air not Oxygen as mentioned in the question. It's probably 200 bar x the capacity of tan k of air in there. how to use wifi hotspot without paying go to a specific depth and set the PPO2 to 1.0 or 1.2 or 1.4 and then just stay either stationary at that depth or kick lightly or even work hard.

## How To Work Out Depth Ppo2

The formula can be reversed to work out the maximum depth at which you can safely dive on a particular mix of Nitrox. The maximum depth (D) can be calculated using this formulae: D = 33 x ((1.4 / FO2) - 1) . Where FO2 is the fraction of oxygen in the mix (D is calculated in feet, to change the formula for meters, use 10 instead of 33). So for example, if the diver wanted to use 50% Nitrox

- Bailed out and simultaneous did max rate ascent to 20ft. Ascent so fast it was off scale of dive Ascent so fast it was off scale of dive computer, a Cochran, which locked out afterwards.
- 29/10/2005 · Depth in ATA: This is our depth unit, we will need to convert this to feet to make it useful to us, if we are plugging in a depth in feet, we divide that number by 33 and then add one to it. Feet into ATA (D in feet/33)+1 = D in ATA. If we are pulling depth out of the formula in ATA and converting to feet, we subtract one and multiply by 33. (Depth in ATA – 1) / 33 = Depth in feet. Instead
- 2/08/2017 · The formula is ppO2 = [ ( depth / 33 ) + 1 ] × FO2 If I use the formula and go by the chart that is in the reading i get the correct results. My issue is when I got an insert for my log book the ppO2 values are different, and I can not figure out how the values were obtained.
- Try taking the battery out and leaving it out for at least 5 minutes. This should allow the transmitter to reset, and often solves a loss of communications. This should allow the transmitter to reset, and often solves a loss of communications.
