For resources to help you master ABGs and ALL the LabVales, we have a FREE Cheatsheet Download at    NURSING.com/LabValues.   At NURSING.com you can learn everything you need to know as a nurse about ABGs including gas exchange, acidosis, alkalosis (metabolic and respiratory), normal lab value ranges, and more.     We also cover key concepts for NCLEX for arterial blood gases.     Our gas exchange nursing care plan covers impaired gas exchange nursing management, impaired gas exchange interventions, impaired gas exchange diagnosis, etc.      Excerpt:    This patient’s lungs were so bad, gas exchange had to take place outside of his body... Learning to read ABGs, and understanding what to do with that information is a very important skill for any nurse, but particularly a cardiovascular ICU nurse.  Hi I am Nurse Abby, and I loved working in the cardiovascular ICU - that was truly one of my favorite nursing jobs. Today I want to share with you the story of one of my MORE complicated patients.
