On the PCC flow sheet, SpO2 is represented by a triangle.

On the PCC flow sheet, SpO2 is represented by a triangle.

• A. True
• B. False
• C. Not used
• D. Unknown

Answer: (B)

SpO2 is the percentage of hemoglobin carrying oxygen, and on the PCC flow sheet it is recorded as a numeric percent value (for example, SpO2 94%) at the time of observation. Using a triangle as the symbol would not convey the actual measurement, so it isn’t how SpO2 is represented. The flow sheet relies on the exact percentage to track trends and guide treatment, such as increasing oxygen or reassessing ventilation if desaturation occurs. Therefore, the statement is false because SpO2 is not shown as a triangle.
