Data Analysis

Directions

Review the patients' data in Table 2. Then, indicate whether the values for Respiratory rate, arterial pH, arterial pCO₂, and arterial HCO₃^– are low, normal, or high. Use the drop-down menus to make your choices. Incorrect choices will prevent further selections.

Decide what type of acid-base balance disorder is the most probable in each patient. Use the drop-down menus to make your choices.

Decide whether the patient is exhbiting respiratory compensation, metabolic compensation, or no compensation.

Your data tables will be transferred to your Laboratory Report.

Equations (f_x)

Determine whether pH is low (acidosis) or high (alkalosis).
Determine whether pH change is caused by abnormal PCO₂ or HCO₃^–. Acidosis could be caused by either a high PCO₂ or a low HCO₃ alkalosis could be caused by either a low PCO₂ or a high HCO₃^–.
If the cause of the abnormal pH is due to a change in PCO₂ then the problem is respiratory; if the cause is a change in HCO₃^– then the problem is metabolic.
Look at the value (PCO₂ or HCO₃^–) that doesn’t cause the abnormal pH. If it is within the normal range then there is not compensation; if it is outside the normal range the compensation is occurring.

Your data will not be saved until the table is completely filled in.
