Final answer:
During CPR, the blood gas values can become messed up due to respiratory acidosis and metabolic acidosis. These imbalances can be identified through lab tests for pH, CO2 partial pressure (pCO2), and HCO3 levels.
Step-by-step explanation:
During CPR, the blood gas values can become messed up due to various factors. One common cause is respiratory acidosis, which occurs when there is excess carbon dioxide (CO2) in the blood. Another factor is metabolic acidosis, which happens when there is lower-than-normal amounts of bicarbonate in the blood. These imbalances can be identified through lab tests for pH, CO2 partial pressure (pCO2), and HCO3 levels.
