What does the Tic-Tac-Toe method involve?
Press to flip
Placing pH, CO2, and HCO3 values in acid, normal, or alkalotic columns to find tic-tac-toe for the primary condition.
What signifies fully compensated respiratory alkalosis in the Rome Method?
Normal pH (7.35-7.45), Low CO2 (< 35), Low HCO3 (< 22)
What does the 'Rome' in the Rome Method stand for?
Respiratory Opposite, Metabolic Equal
What interpretation would you give to pH = 7.27, CO2 = 33, HCO3 = 17 using the Tic-Tac-Toe method?
Metabolic Acidosis (Partially Compensated)
What does a pH of 7.30, CO2 of 40, and HCO3 of 18 indicate?
Metabolic Acidosis (Uncompensated)
What does pH = 7.28, CO2 = 50, HCO3 = 24 indicate?
Respiratory Acidosis (Uncompensated)
Describe full compensation in the context of ABG analysis.
Full compensation occurs when pH is within normal range, but both CO2 and HCO3 are abnormal, indicating the body has fully compensated for the imbalance.
What does a case with pH = 7.37, CO2 = 32, HCO3 = 17 represent in the Rome Method?
Metabolic Acidosis (Fully Compensated)
What is the interpretation of pH = 7.51, CO2 = 47, HCO3 = 32 using the Tic-Tac-Toe method?
Metabolic Alkalosis (Partially Compensated)
Which values indicate uncompensated metabolic acidosis?
Low pH (< 7.35), Low HCO3 (< 22), Normal CO2 (35-45)
In the Rome Method, what does 'Equal' signify?
For metabolic imbalances, both pH and HCO3 move in the same direction (both high or both low).
How do you determine whether a problem is respiratory or metabolic?
By assessing CO2 for respiratory and HCO3 for metabolic imbalances and comparing with pH.
How do you recognize partial compensation in an ABG problem?
When pH is abnormal and both CO2 and HCO3 are also abnormal but not yet normalizing the pH.
What do you consider normal ranges for pH, CO2, and HCO3?
pH: 7.35-7.45, CO2: 35-45, HCO3: 22-26
Give an example of fully compensated metabolic acidosis.
pH = 7.37, CO2 = 33, HCO3 = 17
What pH, CO2, and HCO3 values correspond to uncompensated respiratory acidosis?
pH < 7.35 (Acidotic), CO2 > 45 (Acidotic), HCO3 normal
How do you identify respiratory acidosis using the Rome Method?
High CO2 and Low pH
