Sometimes an individual going through a traumatic experience cannot stop hyperventilating. In such a circumstance, it is recommended that the individual breath into a paper bag or cupped hands as a useful way to avoid an increase in blood pH, which can cause the person to pass out. Explain how this works.
A)Carbon dioxide initially exhaled is reinhaled to help maintain adequate levels of carbonic acid in the blood.
B)It helps to slow their breathing down to prevent excess oxygen from entering the blood.
C)The paper absorbs C to prevent the accumulation of excess C in the blood.
D)The paper bag helps to retain the water vapor leaving the mouth to prevent an increase in the concentration of lactic acid in the body.

Quizplus · Accepted Answer

When a person hyperventilates, they exhale excessive carbon dioxide, which leads to a decrease in carbonic acid levels in the blood. Breathing into a paper bag or cupped hands allows the person to re-inhale some of the carbon dioxide that they exhaled, which helps to maintain adequate levels of carbonic acid in the blood. This prevents an increase in blood pH, which can cause the person to pass out.
