WebJul 12, 2024 · Revisions: 24. The acid-base balance is vital for normal bodily functions. Disruption of this equilibrium can lead to severe complications such as arrhythmias and seizures. Therefore, this balance is tightly regulated. In this article, we will look at the buffering system, responses of the respiratory system and relevant clinical conditions. WebUnder normal physiologic conditions, an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis. The higher the minute ventilation, the more exchange and loss of PCO2 will occur inversely. What happens to blood pH during respiratory alkalosis?
