A patient has an arterial pH of 7.58. What effect will this have on oxygen transport?: A. impaired blood oxygen unloading at the tissues 7. Alkalosis shifts the oxyhemoglobin curve to the left, which increases the affinity of hemoglobin for oxygen. Although this shift increases the arterial Hb saturation and CaO2 (and enhances blood O2 uptake at the lung), it impairs O2 unloading at the tissues.: True 8. A patient has a pH of 7.58 and a PaCO2 of 50 torr. Based on these data, what is the primary acid-base disturbance?: D. metabolic alkalosis 9. To determine the primary acid-base disturbance, first determine whether the pH is low (< 7.35 = academia) or high (> 7.45 = alkalemia). After judging the pH, you then assess the PaCO2. If the pH is low, the primary disturbance must be either respiratory acidosis (PaCO2 > 45 torr) or metabolic acidosis (PaCO2 £ 45 torr). With a high pH, the primary disturbance must be either respiratory alkalosis (PaCO2 < 35 torr) or metabolic alkalosis (PaCO2 ³ 35 torr).: True 10.
