Respiratory care equations are some of the most useful tools available to the practicing Respiratory Therapist and respiratory care students. Not only do the equations provide answers to clinical questions, they help practitioners learn variables in an equation and how those variables may be altered to achieve better clinical outcomes. Respiratory Care Calculations, Revised Fourth Edition prepares students to calculate those equations correctly, and then interpret that data in a meaningful way, resulting in patients benefiting from accurate answers and appropriate applications of data.
With its comprehensive coverage of respiratory care calculations and extensive additional learning resources, readers will find Respiratory Care Calculations, Revised Fourth Edition useful in preparing for their clinical practice and credentialing examinations. Self-Assessment Questions are available in the NBRC format, and can be found at the end of each calculation to enhance and reinforce learning and retention. The book is extremely valuable to both students and seasoned practitioners in all patient care situations.
Over 800 self assessment questions to reinforce correct calculation and retainment of knowledge
Clinical Notes found throughout the text to provide additional explanation or clarification of the equation
Full color design to aid in visualization of equations
Key formulas available on a Cheat Sheet and provided on the inside back cover of the book for quick review
Self-assessment questions follow the examination format of the National Board for Respiratory Care (NBRC)
