The clinical physics and physiology of chronic lung disease, inhalation therapy, and pulmonary function testing Book

I am writing this review in my first year of medical student in London. The reason I say this is because I think this book would be far more useful if I was specialising in pulmonary medicine (and also maybe if I was in the U.S.A.).
There were lots of aspects of this book that I just wasn't able to wrap my head around the science that was being explained. It was extremely complex and I often spent ages on one particular concept, even consulting friends doing engineering, but I didn't make much progress. Many of these parts I just left and accepted that at the moment I won't be able to understand this.
However there were also many parts of this book that I really enjoyed. It was cool to see a lot of the real-world applications of pulmonary physiology and even non-applicable things it was cool to see how our lungs work, it's pretty awesome.
The chapters that I enjoyed (and actually understood) were chapters 4, 6, 7, 8 and 9.
That's not totally accurate though because there were some parts of those chapters that I found really complicated and tedious, and there were some parts of other chapters that I was fond of.
