BOBO the DAN Talk was great!
It shows the truth about diving. The things which i really wanted to know.
The time moved so fast the 4 hours talk was like just a few minutes.
About the jellyfish was very alarming. To know that the box jellyfish families and irukanji has arrived to thailand ,
pulau payar and langkawi is really disturbing. Especially for the malaysian divers who loved to dive
without wetsuits and also swimmers at the beaches.
The box jellyfish stings are not the same like the common jellyfish found in our waters.
They are deadly and leathal.
John did show picture slide taken 2010 but that time malaysia held some tournaments in langkawi
and these findings would mess up the tourim economy
One picture of a small box jellyfish was taken under the jetty of rebak marina.
Other than that THE Decompression Illness. DCS and more.
Many divers just wont accept that they had DCS type I .
Type I DCS is characterised by
Mild pains that begin to resolve within 10 minutes of onset (niggles)
"Skin bends" that cause itching or burning sensations of the skin; or
skin rash, which generally is a mottled rash causing marbling of the skin or a violet coloured rash which is most often seen on the chest and shoulders. On rare occasions, skin has an orange peel appearance.
It is important that this is not confused with other causes of a rash whilst diving. A suit squeeze will generally have a different pattern and look more like bruising, whilst a neoprene contact dermatitis will be in areas where a suit rubs, such as the neck or cuffs.
Lymphatic involvement is uncommon and usually is signaled by painless pitting oedema which is a swelling of the lower limbs that a thumb when pressed in will leave an impression. The mildest cases involve the skin or the lymphatics. Some authorities consider anorexia and excessive fatigue after a dive as manifestations of Type I DCS.
Pain (the bends) occurs in the majority (70-85%) of patients with DCS. Pain is the most common symptom of DCS and is often described as a dull, deep, throbbing, toothache-type pain, usually in a joint or tendon area but also in tissue. The shoulder is the most commonly affected joint in most divers after a shallower than 40 metre dive, whereas the knees are affected more in deep divers. The pain is initially mild and slowly becomes more intense. Because of this, many divers attribute early DCS symptoms to overexertion or a pulled muscle.
Upper limbs are affected about 3 times as often as lower limbs. The pain of Type I DCS may mask neurological signs that are hallmarks of the more serious Type II DCS
What is DCS type I, II, III go to Dive and Medicine threads. There are a lot of posting about it
