What condition may arise from skip-breathing while SCUBA diving?

Skip-breathing refers to the practice of deliberately omitting breaths or taking fewer breaths while diving, which can lead to a significant buildup of carbon dioxide (CO2) in the body. This buildup occurs because the body is still producing CO2 from metabolism, but not enough is being exhaled since breaths are being skipped. When CO2 levels rise, it can result in hypercapnia, a condition characterized by an excess of carbon dioxide in the bloodstream.

Hypercapnia can lead to various symptoms, including headaches, dizziness, confusion, and in severe cases, can impair cognitive function and create serious risks while diving. Keeping adequate ventilation and regularly exhaling is crucial in managing CO2 levels effectively during a dive. Understanding the importance of proper breathing techniques is essential for maintaining safe diving practices and avoiding complications that can arise from poor oxygen and carbon dioxide exchange.
