Question

Excessive voluntary hyperventilation can cause ____________ while involuntary hyperventilation can cause ________________? 1) Hypoxia, Hypercapnia 2) Hypercapnia, Hypocapnia 3) Hypocapnia, Hypercapnia 4) Hyperoxia, Hypoxia

Answer 1

Excessive voluntary hyperventilation can cause hypocapnia (abnormally low CO2 levels), while involuntary hyperventilation often results in hypercapnia (abnormally high CO2 levels), which corresponds to option 3) Hypocapnia, Hypercapnia.

Step-by-step explanation:

Excessive voluntary hyperventilation can cause hypocapnia, while involuntary hyperventilation can cause hypercapnia. Therefore, the correct answer is option 3) Hypocapnia, Hypercapnia. Hypocapnia is characterized by abnormally low blood levels of CO2, often due to an increased ventilation rate that exceeds the body's production of CO2. This condition is commonly driven off by hyperventilating, which might occur during anxiety, panic attacks, or voluntary efforts to breathe deeply. On the other hand, hypercapnia is the presence of abnormally high levels of CO2 in the blood, commonly occurring in situations where respiratory functions are impaired, such as with certain diseases or respiratory depression due to drug use. This result is typically seen with involuntary hyperventilation caused by panic attacks, severe pain, asthma attacks, or other medical conditions.
