DANB General Chairside Practice Test – Prep, Practice Questions & Study Guide

Instructing a hyperventilating patient to breathe into cupped hands primarily aims to increase the levels of carbon dioxide in their bloodstream. When a person hyperventilates, they expel a significant amount of carbon dioxide, leading to a state of respiratory alkalosis, which can cause symptoms such as lightheadedness, tingling in the extremities, and anxiety.

By breathing into cupped hands, the patient re-breathes some of the exhaled carbon dioxide, helping to restore balance to the carbon dioxide levels in their blood. This technique serves as a simple and effective method to alleviate the physiological effects of hyperventilation by counteracting the loss of carbon dioxide.
