Question
Why does a hyperventilating individual breathe in a bag?Question 1Select one:a.This can increase PaO2 back to normal.b.This can increase PaCO2 back to normal.c.This can decrease PaO2 back to normal.d.This can decrease PaCO2 back to normal.
Solution
The answer is b. This can increase PaCO2 back to the normal.
When an individual hyperventilates, they breathe out too much carbon dioxide (CO2), which decreases the level of PaCO2 in the blood. This can lead to symptoms such as dizziness, light-headedness, weakness, shortness of breath, a rapid heartbeat, and feelings of anxiety.
Breathing into a bag helps to increase the levels of CO2 that the person inhales, which can help to bring the PaCO2 levels back to normal. This is because the bag traps the exhaled CO2, so when the person breathes in from the bag, they are inhaling a higher concentration of CO2 than they would be from the air. This can help to correct the imbalance of gases in the blood and relieve the symptoms of hyperventilation.
