Question: 1 / 625

What causes bubbles to form in a scuba diver with inadequate decompression?

Increased water temperature

Reducing barometric pressure

Bubbles form in a scuba diver with inadequate decompression primarily due to reducing barometric pressure. When a diver ascends too quickly from the depths, the pressure surrounding them decreases rapidly. At higher pressures, nitrogen dissolved in the body tissues is at a stable level. As the diver ascends and the pressure drops, the nitrogen that was dissolved in the tissues becomes less soluble and begins to come out of solution, forming bubbles. This process is a critical component of decompression sickness, commonly known as "the bends."

Understanding the role of pressure is crucial in preventing decompression sickness. It is important to adhere to safety protocols, which include making gradual ascents and allowing for decompression stops as necessary to manage the nitrogen levels in the body and avoid bubble formation.
