Answer:
Hyperventilation is a breathing pattern characterized by rapid and deep breaths, often resulting in an increased ventilation rate. This altered breathing pattern can lead to changes in the blood gas levels. Let's analyze the options provided to determine which holds true after a person hyperventilates.
A) High pO2 in blood:
B) Low pO2 in blood:
C) High pCO2 in blood:
D) Low pCO2 in blood:
Conclusion:
Hyperventilation is a breathing pattern characterized by rapid and deep breaths, often resulting in an increased ventilation rate. This altered breathing pattern can lead to changes in the blood gas levels. Let's analyze the options provided to determine which holds true after a person hyperventilates.
A) High pO2 in blood:
When a person hyperventilates, there is an increased intake of oxygen due to the rapid and deep breaths. This leads to an increased oxygen supply to the lungs and subsequently the blood. As a result, the pO2 levels in the blood can increase.
B) Low pO2 in blood:
Hyperventilation is not typically associated with a decrease in pO2 levels. Therefore, this option is not correct.
C) High pCO2 in blood:
Hyperventilation results in the elimination of carbon dioxide (CO2) from the body at a faster rate. The increased respiratory rate and depth lead to the removal of more CO2 from the lungs. Consequently, the pCO2 levels in the blood can decrease.
D) Low pCO2 in blood:
As mentioned above, hyperventilation causes a decrease in pCO2 levels in the blood due to the rapid elimination of CO2. Therefore, this option is correct.
Conclusion:
Based on the analysis, the correct answer is (4) A,C. After a person hyperventilates, there will be high pO2 levels and low pCO2 levels in the blood.
