patient’s cardiovascular system allows you to quickly identify any alterations that may complicate the patient's recovery. A complete assessment focuses not only on the heart—but on the arterial and venoussystems as well—and includes an interview, physical exam, and diagnostic testing.
AND THE PALPABLE PULSE
Cardiovascular system means the system of heart and bloodvessels of human body. The term “cardiovascular” is a combination of two word; “Cardio” and “vascular”. The term “cardio” is derived from “cardiac” meaning Heart and the term “vascular” means...
