The Cardiovascular-Respiratory Score (CVRS) is a subset of the Trauma Score. It consists of all the elements of the Trauma Score except for the Glasgow Coma Score. It can be used as a measure of the physiologic condition of the injured patient.
Parameters:
(1) respiratory rate
(2) respiratory expansion
(3) systolic blood pressure
(4) capillary return

cardiovascular-respiratory score =
= (points for respiratory rate) + (points for respiratory expansion) + (points for systolic blood pressure) + (points for capillary return)
Interpretation:
• minimum score: 0
• maximum score: 11
• The higher the score, the better the prognosis.
• A score of 0 to 3 indicates a poor prognosis.
