Usage

nvps_pain_score(face, activity, guarding, physiology_vital_signs, respiratory)

Value

A list containing:

NVPS_Score

The calculated total score (Range 0-10).

Interpretation

Clinical interpretation of pain severity (No/Mild, Moderate, Severe).

face

Numeric (0-2). 0: No particular expression or smile. 1: Occasional grimace, tearing, frowning, wrinkled forehead. 2: Frequent grimace, tearing, frowning, wrinkled forehead.

physiology_vital_signs

Numeric (0-2). 0: Baseline vital signs unchanged. 1: Change in SBP > 20 mmHg or HR > 20 bpm. 2: Change in SBP > 30 mmHg or HR > 25 bpm.

respiratory

Numeric (0-2). 0: Baseline RR/SpO2/compliance unchanged. 1: RR > 10 above baseline, 5% decrease in SpO2, or mild ventilator dyssynchrony. 2: RR > 20 above baseline, 10% decrease in SpO2, or severe ventilator dyssynchrony.
