How can I increase my bottom time?

All you have to do is sit/stand up straight and inhale while you slowly count to five. Then exhale while you slowly count to five. Repeat. Practice that throughout your day until your breathing falls into that rhythm automatically.

Are night dives scary?

The thought of descending into dark waters with only the beam of a dive flashlight for light, the eerie calm waters and the very limited visibility that keeps you imagining what creatures lie outside your light beam can be intimidating and daunting.

How does night diving work?

On a night dive, your light source is never more than five or 10 feet away, so the water doesn’t take away any of the light spectrum. Redefine “night.” When the sun is low in the sky, very little light penetrates the surface, making it pretty dark underwater even when there is still a fair amount of light above.

Why do scuba divers need to exhale air when they ascend to the surface of the water?

As the diver ascends, the pressure decreases. According to Boyle’s Law, this causes an increase in the volume of the lungs. The diver needs to exhale to adjust for the change in volume caused by the change in pressure.

Why can’t scuba divers surface quickly?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.

How would you most efficiently provide oxygen to a breathing injured diver?

Providing care to an injured diver with a demand-valve regulator. This is the most efficient way to deliver oxygen, since the demand-valve only delivers oxygen when the diver inhales.

What percentage of oxygen do you use when scuba diving?

Oxygen and scuba diving. As divers, we generally know the wider applications of oxygen. It constitutes 21 percent of air, but we can change the concentration in our tank for nitrox or trimix diving. In cases of suspected DCS, we administer 100 percent oxygen.

Is it harder to breathe head-up or head-up scuba diving?

With a standard scuba kit, diving in a head-up position will make it harder to breathe. This is because the lungs are lower than the mouth, which means they’re experience higher pressure. This reduces the diver’s ability to take a full inspiration or full exhalation.
