This easy to read booklet is fully illustrated to focus on the traces of NIV and shows details that are not always easy to see and understand. The authors give advice on how to identify and correct problems. It gives both information about typical and less typical clinical cases, to steer the reader towards the real world. This nice document is a classic example of how doctors can simplify complicated subjects, mainly by “talking about what they do every day”.
