I'd give this a solid 3.75 stars.
I think Paul was incredibly vulnerable, showing the sides that burnout can create in you and at the effect that had on his family, and own mental wellbeing.
This book did not go the route I expected. I had anticipated a greater emphasis on the emergency room, patient interactions, crazy medical situations, interesting stories, etc. But this is much more of a memoir, with the ER in background of this doctors life. He speaks to his experiences in medical school, residency, and the beginning of his career and development of his family.
For me, the most interesting part of this book was his discussion on empathy and compassion, and how changing the porosity of your empathy makes you an effective healthcare worker in an emergency setting. When there is a 7-year old drowning victim on the table, thready pulse, walking the line between death and life, you cannot view them as a person. if you allow yourself to feel the enormity of the child dying in front of you, you'll freeze. You can't make any decisions.
You have to view it as an airway, because we know how to manage an airway. Then breathing, circulation, etc.
It's sounds cold, and is certainly a shock, but to work in an ER one has to develop the skill to learn how (and when) to stop processing people as human so you can save their lives. Then, in a different setting you can open that empathy porosity, like the aperture of a camera, and show kindness in a situation when it is needed.
I somewhat read this in preparation for my transition to becoming an ER nurse, partially because I found it in the thrift store. Definitely has some good pearls, not technical at all, and Paul has had a nuanced life. I would definitely read his other book if I could find it.
