Most charts score from 0-3, according to the degree of deviation away from 'normal range'.

A total score is then calculated.

Question: Now what should you do?

Answer: When the total score has been calculated, various actions are triggered, for example:

• Low score, e.g. <3: Continue monitoring
• High score, e.g. 3 or more: Intervention is required
