Hough’s Cardiorespiratory Care E-Book

Alexandra Hough

(2017)

Abstract

The latest edition of this must-have text book promises an evidence-based and practical approach covering the very latest in cardiorespiratory care.

The textbook covers a wide range of cardiorespiratory conditions and discusses treatment of patients in different clinical settings such as critical care, the ward area and out-patient departments. It begins with physiology and pathology and progresses into a detailed patient assessment section and a discussion of specific respiratory and cardiac conditions. The final section covers different groups of people who may require physiotherapy such as infants, children, and adults with specific conditions including a considered section on palliative care.

Critical thinking is facilitated by clinical reasoning boxes in the text, and problem-solving is aided by case studies at the end of each chapter. There are also relevant practice tips to enable transfer of learning into the clinical environment. The text is supported by over 280 line drawings and diagrams along with over 70 x-rays and photographs to further illustrate the points under discussion.

  • Q & A case studies, with scans and x-rays
  • Outcome measures for problems and diseases
  • Boxes with learning and practice tips to encourage reflection
  • Tables with definitions, normal values and comparisons
  • Practical techniques described with precision
  • Expanded cardiovascular section
  • Updated practical details on physiotherapy techniques
  • Extra chapters on surgical complications and interventions
  • Comprehensive coverage of Critical Care procedures and rehabilitation
  • Practicalities of the management of children and infants

Update on the evaluation of outcomes
