  • Monitor patients' blood pressure and heart rate using electrocardiogram (EKG) equipment during diagnostic and therapeutic procedures to notify the physician if something appears wrong.
  • Monitor patients' comfort and safety during tests, alerting physicians to abnormalities or changes in patient responses.
  • Explain testing procedures to patient to obtain cooperation and reduce anxiety.

  • Inject contrast medium into patients' blood vessels.
  • Observe ultrasound display screen and listen to signals to record vascular information such as blood pressure, limb volume changes, oxygen saturation and cerebral circulation.
  • Assess cardiac physiology and calculate valve areas from blood flow velocity measurements.
  • Compare measurements of heart wall thickness and chamber sizes to standard norms to identify abnormalities.
  • Activate fluoroscope and camera to produce images used to guide catheter through cardiovascular system.
  • Enter factors such as amount and quality of radiation beam, and filming sequence, into computer.
  • Conduct tests of pulmonary system, using spirometer and other respiratory testing equipment.
