This is a book that should be in all the libraries of country houses, but which may also be aimed at city dwellers (though I doubt it). It is still a little improvement, but for my part I think the key is there, it is clear, concise, and gives only necessary information. So if you live far from a hospital and not simply pick up the phone for you that come to the rescue in 02 minutes as downtown, buy this book USEFUL. In terms of delivery, packaging and nickels possible!
