Diving oxygen consumption posture

There are really a few words about diving gas. First of all, don't use an incomplete cylinder. Many people will pick up the equipment because they have dropped it, and eventually something will happen. In order to ensure safety, it is natural to check everything before diving.

The gesture of running out of air slides on the chest, indicating that there is a serious problem in diving-running out of air. If you find that you have no air, you should do this immediately, ask your potential partner for spare air, and then enjoy the air or rise urgently.

A gesture of "cutting your throat". Underwater, this gesture means telling the potential partner that he can't breathe oxygen, and the situation is urgent.

The first reaction of diving is to take out the spare breathing head and put it in my mouth or plug it with your own spare breathing head.

The common causes of air exhaustion crisis are 1 and diving too deep.

With the depth getting deeper and deeper, the gas consumption rate also increases sharply. You may need more gas to decompress and stay. A barrel of ordinary aluminum bottle 80 is not used for decompression diving. Running out of air will put you in a dangerous emergency. If you really encounter this kind of emergency, you should try to increase the diving time at a shallow depth that is easy to reach the water surface.

2. Stop for too long

Sooner or later, you will use phosgene source. Plan ahead how much remaining pressure you have to pay back and prepare to rise. During diving, always take the initiative to check the residual pressure and return on time. Don't force it.

3. Too hard

Countercurrent or lack of neutral buoyancy control will affect gas consumption. The deep activity may increase the gas consumption rate by 20 times. If you are not used to diving under strong current, you'd better receive special training before you leave, and don't rush into the water.

4. Didn't pay attention to the residual pressure table

Always check the residual pressure and communicate with your potential partner, so that both parties know how much gas is left in each other's body.

5. Ignore the influence of anxiety

Anxiety consumes more gas than strenuous exercise. Try to keep breathing normally. If you feel anxious, pay close attention to your residual stress, which may drop faster than usual.
