Explanation This is an abnormal phenomenon where the rate of breathing increases with the depth for a period longer than normal. Breathing too fast and deeply results in the depletion of carbon dioxide gas from the blood and lungs, which causes chemical changes in the gaseous composition of oxygen and carbon dioxide in the blood. Controlled hyperventilation is a phenomenon that helps divers to increase the time to remain underwater...

Chapter 20, Problem 6RQ

Summary Introduction

To review:

Whether the following statement, “Hyper-ventilation prior to a breath-hold dive can be dangerous,” is true or false.

Introduction:

Hyperventilation refers to excessive breathing. The major symptoms of hyperventilation include dizziness, suffocation, anxiety, numbness in fingers and toes, fatigue, and pain in chest. It may lead to blurred vision and a feeling of unconsciousness. The situation of hyperventilation is combated by taking deep breaths and relaxing.
