Respiratory Acidosis and Alkalosis | Physiology

Welcome back to yet another video on sqadia.com! So, by now you probably know how to figure out the different types of acid-base disorders, which we talked about in detail in our previous video on the acid-base approach, which were: 🟡 Metabolic Acidosis 🟡 Metabolic Alkalosis 🟡 Respiratory Acidosis 🟡 Respiratory Alkalosis We have discussed Metabolic acidosis and Metabolic Alkalosis. Our topic for today’s video is “Respiratory Acidosis and Alkalosis”. We’ll be discussing the causes of Respiratory Acidosis and Alkalosis. Now, Respiratory acidosis and alkalosis are by far the simplest disorders to grasp, mainly owing to the short number of causes. So, first, we’ll start with respiratory alkalosis. ▬ 📌 Respiratory Alkalosis Causes Respiratory alkalosis is when the pCO2 decreases, and the pH is more than 7.45. The Acid-base equilibrium equation states: CO2 + H2O ↔ H⁺ + HCO3¯ So, whenever there is a low CO2 level, the equation will go left to correct the low CO2. As a result, the H+ ions decrease, creating a high pH. Causes of Respiratory alkalosis include: 🟠 Hyperventilation 🟠 Aspirin overdose ▬ 📌 Respiratory Acidosis Causes Moving on now to Respiratory Acidosis. This is when the pH is low and the pCO2 is high. So, using the equilibrium equation, if the CO2 gets high, the equation moves right, in order to compensate and this causes the H+ to increase, resulting in an acidotic state. Causes of Respiratory acidosis include: 🟢 Hypoventilation 🟢 Narcotic Use 🟢 Muscle weakness So, that was an overview.
