VAS in COPD

Q: What does VAS stands for in Rome criteria for COPD exacerbation?

Answer: Visual Analog Scale (VAS)

The Rome criteria for COPD is designed to simplify the classification of respiratory symptoms during exacerbations into mild, moderate, or severe. It consists of the following parameters:

1. Visual Analog Scale (VAS) at a scale of 0 to 10

2. Respiratory Rate (RR)

3. Heart Rate (HR)

4. Oxygen Saturation (SaO₂): Resting levels on room air or baseline oxygen

5. C-Reactive Protein (CRP) as a blood marker for systemic inflammation (mg/L)

Evaluation of arterial Blood Gases (ABG) has also been included if available.

Initially, it was designed to be used only in outpatient settings, but experts now believe it can also be used in inpatient settings. A couple of examples of the utility of this score are prescribing glucocorticoids for a moderate exacerbation of COPD or admission to the ICU for mechanical ventilation.
