WebbFor every 10 mmHg decrease in pCO2, the pH will increase by 0.08. So if your pH is too low (too acidic), you should decrease your CO2 (an acid) levels and vice versa. Remember, you change your pCO2 by changing the respiratory rate (because tidal volume is usually set and never touched again).

WebbThe tidal volume decreased by only a small amount and the respiratory rate decreased as well. The body was requiring more oxygen to keep up with physical demands placed on the body by exercise, thus the subject was breathing more frequently, inhaling oxygen and releasing more CO2. Webb28 sep. 2024 · Volume of gas that reaches the alveoli each minute VA = (VT - VD) x RR VD is greater than anatomic dead space in diseases with a V/Q mismatch (e.g., pulmonary embolism). If alveolar ventilation increases (i.e., hyperventilation ), more CO2 is exhaled and the PaCO 2 decreases.
