Preventing Hypoxia in Scuba Diving


Hypoxia is a medical condition wherein your body is deprived of oxygen, which could lead to serious tissue damages

Here are simple ways to prevent hypoxia during your dive

Even the most experienced divers could encounter hypoxia if they do not take proper precautions. Divers usually experience hypoxia during altitude dives, since the air pressure decreases gradually as you go deeper underwater, thus, providing less oxygen.

Symptoms of hypoxia include:

  • fatigue
  • shortness of breath
  • light-headedness
  • exhaustion

If these symptoms are experienced underwater, it is best to be escorted by your dive buddy as you resurface SLOWLY. It is ideal to resurface slowly by stopping and familiarizing yourself with the water level at least every 3 feet. You may also equalize your ears as you stop at each level to prevent ear problems as well.

In order to prevent hypoxia, you should make sure to rest before you dive. Resting would provide your body an ample supply of oxygen for such activities. Try also not to strain yourselves when hauling your dive equipment. And once you get into the water, make sure that you catch your breath before descending underwater. Resurfacing slowly would prevent your body from shock caused by the sudden change in pressure, hence, preventing hypoxia and decompression sickness from occurring. If you live at a high altitude area, then it is best that you try to familiarize your body with the sudden change in air pressure by staying in lower places for a while before scuba diving in the ocean. Proper training is very essential in scuba diving and it is also best to be trained by certified dive centers.
