Question

Dive suits for undersea exploration have which type of device attached to help the diver breathe

Answer 1

Scuba divers wear dive suits with scuba tanks filled with compressed air for breathing underwater. They monitor their air supply with gauges on the tank and need to ascend slowly to avoid decompression sickness.

Step-by-step explanation:

Dive suits for undersea exploration typically have a device known as a scuba tank attached to help the diver breathe. Scuba stands for Self-Contained Underwater Breathing Apparatus, and it holds a supply of compressed air that the diver uses while underwater. The tank's pressure typically ranges from 200 to 300 atmospheres, allowing the diver to carry a sufficient amount of air to breathe for a duration depending on the dive depth and the diver's air consumption rate. Scuba divers are trained to monitor their air supply using gauges attached to the tank, which indicate both the quantity of air remaining and the pressure of the gas.

Scuba divers must manage their dive time and ascent carefully to avoid decompression sickness (DCS). To prevent DCS, divers should ascend slowly or perform decompression stops as needed. If a diver does get DCS, treatment often involves hyperbaric oxygen therapy in a recompression chamber.

Answer 2

The device attached to the diving suits is called a diving regulator. This device allows you to breathe under water, however it doesn't breathe for you.

A diving regulator reduces pressurized gas to ambient pressure and delivers it to the diver. The gas used in the diving regulator may be a variety of specially blended gasses or it can just be air.
