What can excessive depth result in during a dive?

Excessive depth during a dive leads to higher air consumption due to the increased pressure acting on the diver's body and the air they breathe. As a diver descends, the surrounding pressure increases, which causes the air in their tank to become denser. This denser air requires more frequent breathing to achieve the same amount of oxygen exchange, thereby increasing the overall air consumption rate.

Diving deeper means that the diver must also work harder to overcome the increased pressure, which can increase their physical exertion and oxygen needs. This higher oxygen demand results in quicker depletion of the air supply, impacting the overall duration of the dive and necessitating additional considerations for planning and safety. Therefore, being aware of air consumption is critical for deep divers, as they need to manage their resources effectively to ensure a safe and enjoyable dive.
