As a student and teacher of Polysomnography for 14yrs, I learnt a lot from my students. A lot happens in the classroom beyond teaching. Classroom taught me how to simplify the complex material for students to understand. This book is a compilation of all I learnt in the classroom while teaching and what was created on the whiteboard to simplify things. This book is not a substitute for AASM Scoring manual. It is just my approach to scoring Sleep and associated events. This book is not for teaching everything about Polysomnography but it is about an “Algorithmic Approach” to Sleep scoring and associated events. In this book, Expert scorers will find a refreshing new approach to Scoring Sleep and associated events and beginners in the field of Sleep technology will find a guided and methodical approach to learn about Scoring Sleep and associated events. – Author
