Cardiovascular technologists specialize in using specialty imaging equipment to diagnose heart and blood vessel diseases and guide specialized treatments like balloon angioplasty. Cardiovascular technologists also use ultrasound machines to create images of the blood flow of the heart, allowing physicians to diagnose heart disease.
Surgical technologists, or surgical techs, are an important part of a surgical team. They are responsible for ensuring an operating room and equipment is sterile and ready for surgery.
Additionally, surgical techs are responsible for organizing and passing instruments to surgeons and assistants as well as counting surgical equipment after the operation. They also prepare patients for surgery by cleaning, preparing, and disinfecting the surgical site.
Orthotists and prosthetists help design and fit individuals for braces and artificial limbs to help those who have lost a limb due to illness or traumatic injury be able to move independently.
Technology has created big advances in prosthetic devices, including artificial legs that allow people to run and artificial hands that are controlled by the arm muscles.
