Missing Russian Diver Found Dead In Phuket

Recommended Posts

No, I am not.

Since you are in the industry, can you answer the questions I asked in a previous post?

Can someone rent scuba "EQUIPMENT" without producing a certificate on Phuket?

Can someone buy scuba "EQUIPMENT" without producing a certificate on Phuket?

Definition of SCUBA - "Self-Contained Underwater Breathing Apparatus" - not just a wetsuit, flippers and speargun.

I also freedive often for abalone. I was taught that one should not do more than two dives in quick succession. Always spend a few minutes at surface in between. Sounds like from the article that he was doing many in quick succession? (snipped)

Let me try to explain the reason for this.

First understand two things :-

  1. The urge to breath is caused by the build up of carbon dioxide in the body, not the lack of oxygen.
  2. You brain needs oxygen levels in between certain parameters to function . The level of oxygen is described as the partial pressure of oxygen (PPO2). At the surface the PPO2 in the air the diver breathes is 0.21 (21% expressed as a decimal). The PPO2 increases as you dive down. At ten metres underwater the ambient pressure is double and so pressure of the air in the divers lungs also doubles and the (PPO2) would be 0.42.

At the surface a freediver commonly hyperventilates before diving. Most people believe this elevates oxygen levels in the body but what it actually does is lower carbon dioxide levels so extending the time before the breathing reflex is triggered. As they dive and swim the body metabolizes oxygen and converts it to carbon dioxide, obviously the longer they are down the more oxygen is metabolized and the more the PPO2 also drops. Now at depth and under pressure PPO2 is kept within limits but as you ascend the ambient pressure drops sharply and with it the PPO2. If the PPO2 drops below 0.16 you run the risk of blacking out abruptly, shallow water blackout. If the diver is not positively buoyant he will sink back into the water.

Now if the diver makes several dives in quick succession the PPO2 levels in the blood don’t have time to return to normal and the risk of a blackout is greatly increased.

What you said is correct except hyperventilating increases the chance of shallow water blackout as divers tend to stay down longer due to the lack of breathing reflex ( less CO2 in the blood).

I believe it will be the case of "falang went scuba diving and drowned" just because many Thais (I think cops and investigators can as well be included) have no idea what scuba is, for them diving (any) = scuba diving, these words just come together...

Exactly what I have been trying to say, and the FIRST thing an insurance company will ask the next of kin is, 1) was he certified and/or 2) was he with a qualified dive instructor. All because Thai Policeman puts in his report "farang go scuba diving and drown" when in fact, he was free diving. This is why I hope they investigate this incident properly.

“It appears from his scuba suit and equipment that he was an experienced diver. We know that he had dived in the area before,” said Pol Lt Col Pachai Mattayan of Karon Police.

“It looks as though he dived deep, because some of the fish he brought back up to the boat before he disappeared live at least 10 metres below the surface.”

"scuba suit and EQUIPMENT" - since when are flippers and a speargun classified as "scuba equipment."

This is what lead me to believe he was scuba diving, however, due to the little information we have, and the photos, I have conceded he may have been free diving at the time, and hope this is the case for insurance purposes for his family.

In relation to mentioning insurance, I bought it up, because I hope Thai Police do not just write this off as "drowning whilst scuba diving" because then the insurance may refuse to pay.

I'm very disappointed to see you have learned nothing from our earlier discussion. This also refers to your next posts.

So, can someone hire scuba equipment without producing their certification on Phuket? Also, can someone buy scuba equipment without producing their certification on Phuket?

My point is there is not such thing as a scuba suit! I pointed that out pages ago. It called a wetsuit! Yet you keep referring to it in the poorly worded article as if though SCUBA tanks were used. Think whatever you want!

If you have a quick read through my posts you will see I have called it a "wetsuit." It was the Police statement of "scuba suit and equipment" that made me think he was scuba diving. I don't classify "scuba equipment" as flippers and a speargun, but hey, that's the BIB for you, along with some ordinary journalism.

Anyway, do you know of any good Indian tailors in Patong that can make me a "scuba suit" in the colour I want? :) :) :) :)
