In particular you are required to give appropriate credit (or attribution) to the author (me) for any material from this text that you use. Some published texts do this (e.g. Hasan: Handbook of Blood Gas/Acid Base Interpretation) including a thanks in the preface. Other books use selected parts without such attribution (e.g. Respiratory Care Plans: Principles and Practice (2015) in acid-base chapter - see example at bottom of this page). Anyway writers of various published texts use this on-line text as a source of material for their books so that is some recognition.
