MEDICAL PHYSIOLOGY

Detailed explanation-1: -Respiratory acidosis typically occurs due to failure of ventilation and accumulation of carbon dioxide. The primary disturbance is an elevated arterial partial pressure of carbon dioxide (pCO2) and a decreased ratio of arterial bicarbonate to arterial pCO2, which results in a decrease in the pH of the blood.

Detailed explanation-2: -Chemoreceptors, Breathing, and pH Both events have acid–base consequences. Hyperventilation eliminates CO2 faster than it is being produced and, as a result, pH increases; hypoventilation eliminates CO2 more slowly than it is being produced and, as a result, pH decreases.

Detailed explanation-3: -As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing (respiratory compensation). Breathing faster and deeper increases the amount of carbon dioxide exhaled, which raises the blood pH back toward normal.

Detailed explanation-4: -The blood carries carbon dioxide to the lungs, where it is exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases (acidity increases).

Detailed explanation-5: -When you breathe faster, the lower carbon dioxide level in your blood can lead to respiratory alkalosis. Respiratory alkalosis is usually caused by over-breathing (called hyperventilation) that occurs when you breathe very deeply or rapidly.
