The exercise of shallow respiration or skip respiratory in an make an effort to conserve respiratory gas need to be avoided as it is actually inefficient and tends to induce a carbon dioxide buildup, which may lead to headaches plus a reduced ability to Get better from a respiration gasoline source emergency. The respiration equipment will generally enhance useless space by a small but major amount, and cracking stress and stream resistance in the need valve will lead to a Web work of breathing boost, that can lessen the diver's potential for other work.
