What would happen to a diver who does not exhale while surfacing from a 30 m dive?

Why does diving 30 m below sea level affect our bodies more than being a building 30 m above sea level?

Diving 30mbelow sea level affects our bodies more than being in a building 30m above sea level because when you’re below sea level the pressure of your lungs expand and can fill with water not being able to breathe.

What happens when you surface too fast?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs.

Why do scuba divers need to exhale air when they ascend to the surface of the water apply Boyle’s Law in discussing your answer?

Its volume expands or contracts with even a few feet of depth change, so Boyle’s Law means it’s important to breathe in and out without trying to save tank air by breath-holding. It’s vital to release compressed air while ascending to prevent lung damage.

Why divers must breathe out as they rise to the surface?

Since Pneumothorax involves injury to lungs, it causes acute pain in the chest which may be accompanied by coughing up blood. Pneumothorax worsens as a diver ascends because the pressure on the damaged lung increases with the ascent.

Why do scuba divers lungs not collapse as they descend?

As divers descend into the ocean, the external pressure on their bodies increases by about 1 atm every 10.06 m. To balance this it is necessary to increase the pressure of the air they breathe from tanks or pumped to them from the surface so that their chests and lungs do not collapse.

How does this law relate to diving?

Scuba Diving Safety Rules Derived From Boyle’s Law

Don’t Hold Your Breath Underwater – According to dive training organizations, a diver should never hold his breath underwater because if he ascends (even a few feet) to an area of lesser water pressure, the air trapped in his lungs will expand according to Boyle’s Law.

What happens if you surface too quickly while diving?

If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening.

What happens if you fart while scuba diving?

Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.

Why does scuba diver need to exhale as he need to ascend in 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 underwater divers are advised not to hold the breath unnecessarily while diving?

If the air is held inside the lungs while diving, this air is compressed due to water pressure and this same air may expand while rising up in the water, creating fatal pressure over the walls of the lungs.

Why beginning scuba divers are taught never to hold their breath while ascending from deep water?

When the diver surfaces- one of the most important rules is to be continuously breathing. Never hold your breath when ascending. This is due to the air in the lungs will start to expand because there is less pressure of the water exerted on the body. Holding your breath can cause catastrophic injury to divers lungs.
