Rebreathing (simply by placing a paper back over the head of the person who experiencing a panic attack) stimulates
a. Hypoventilation and respiratory acidosis
b. Hyperventilation and respiratory acidosis
c. Hypoventilation and respiratory alkalosis
d. Hyperventilation and respiratory alkalosis
Ans:-b) Hyperventilation and respiratory acidosis
concept:- CO2 is responsible for stimulation of respiratory drive.
when we rebreath in a paper bag , then amount of CO2 in inhaled air increases which inc the PCO2 in blood.
this CO2 cross blood brain barrier and stimulate the respiratory center to cause hyperventilation.
And as level level of CO2 increases it lead to resp acidosis.
