Noninvasive

• Noninvasive techniques or noninvasive technology have roughly the same important parameter--the technique or technology never pierces the patient's body, and there is no incision into the skin or removal of the patient's tissue.
  
  

Cardiovascular

• The cardiovascular system is made up of the heart, which pumps blood, and blood vessels, which carry nutrients and oxygen throughout the body. When a patient is suffering from a cardiovascular disease, these are the areas of the body that it will be affecting.
  
  

Purpose

• Noninvasive cardiovascular technology is used to see inside the patient to examine his cardiovascular system. Instead of surgeons needing to open a patient up to see his heart or take blood samples to see the vessels, noninvasive cardiovascular technology such as an ultrasound is used to calculate, analyze and interpret the current state of the patient's cardiovascular system.
  
  

Ultrasound

• An ultrasound is a medical procedure that uses sound waves, which is why it's sometimes called a sonogram. The high frequency sound waves travel through the patient and form a picture of her internal organs, tissues and blood flow inside the body. Since an ultrasound can pick out blood flow and organs, such as the heart, it's the perfect noninvasive cardiovascular tool.
  
  

Training

• Noninvasive cardiovascular technology has become so common and so advanced that it now requires a course of study, if not a two-year degree in itself. Those who decide to earn this particular degree will learn how to operate technology such as the ultrasound and how to interpret the results.
