Before a diver dives will he will take a deep breath or hyperventilate?

Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.


Why do scuba divers need math?

How do divers get their air?

Divers typically get their air from a tank filled with compressed air, which they carry on their backs. This tank is connected to a regulator that controls the flow of air, allowing divers to breathe comfortably underwater. In some cases, divers may use alternative gas mixtures, such as nitrox or trimix, to extend their dive time or enhance safety. Surface-supplied diving systems are another option, providing air through a hose from a support vessel.

How can the increase in the level of nitrogen be avoided by deep sea divers?

By breathing nitrox (gases where the %O2 is higher as compared to air) or mixed gases (e.g. adding in helium) so that the partial pressure of nitrogen is reduced.
