Figure 2. ( A ) Henderson-Hasselbalch equation for buffer systems; pH is a function of the pKa of applied weak acid (HA) and the logarithmic ratio of conjugate base (A − ) to weak acid concentration. ( B ) Henderson-Hasselbalch equation for the carbonic acid conjugate base buffer system; pH = 7.4 ... More

Figure 7. The dysfunctional organ as indicated by the abnormal buffer component is denoted by a circular “X” in parts B – E , along with an adjacent arrow indicating directionality of deviation from normal ABG values. ( A ) pH = 7.4 (normal), PCO 2 /[HCO 3 − ] is a straight line (20:1 ratio). ( ... More

Figure 8. Abnormal pH is crossed out to emphasize before-and-after results of pH of compensation. The dysfunctional organ, as indicated by an abnormal ABG buffer component value, is denoted by a circular “X” in parts B – E because they cannot contribute to the compensatory response. An adjacent ... More
