1. MAJOR DUTIES: Serves in a multi-role (scrub, monitor, and circulator) capacity as a 
Cardiovascular Medical Instrument Technician and functions cooperatively as a member of the 
cardiovascular laboratory team, which performs diagnostic and therapeutic procedures as a service to 
physicians who directly supervise the procedures. The technician assists the physician(s) and team 
members during a variety of highly complex, potentially life-threatening invasive cardiovascular 
procedures on stable and unstable patients throughout the lifespan continuum.

2. SCRUB - Participates with the physician in planning procedures, then initiates preparation for 
physician-directed procedure and independently either makes recommendations about procedures or, in 
some situations, make changes to procedures. Assists in identifying and selecting 
patient/procedure-specific catheters, supplies, equipment, and contrast medium and volume, and then 
manipulates or changes supplies or instruments in
order to meet the requirements of the procedure. Varies technique to accommodate patients 
condition and changes conventional methods to produce acceptable results. Sets up sterile field and 
prepares heparinized saline solutions. Maintains aseptic technique, manipulates wires and 
catheters, anticipates catheter tip location, operates fluoroscopic single-plane and bi-plane x-ray 
equipment and selects appropriate angulations and positions, x-ray table and an image intensifier for 
optimal display of angiographic anatomy while assisting the physician throughout the following 
procedures:

Selective vessel and heart chamber pressure recording; selective vessel and chamber blood sampling 
and/or shunt detection studies via oximetry; selective contrastangiography (aortic, coronary, left 
ventricle, peripheral vascular, pulmonary, and renal) via manual or power injection of radiopaque 
contrast media; angiojet, coronary rotational atherectomy; coronary intravascular ultrasound, 
angioplasty and stent implantation; foreign body retrieval from heart or great vessels; permanent 
pacemaker implantation and/or leadwire insertion; venous access device implantation; transvenous 
temporary pacing catheter insertion; thermodilution catheter insertion and cardiac output 
measurement; intra-aortic balloon catheter insertion; endomyocardial biopsy; pericardiocentesis; 
drug response studies; electrophysiology studies; ablations; automatic implantable cardiac 
defibrillators; pharmaceutical or exercise stress angiography; intracoronary anticoagulant, 
thrombolytic, and/or nitrate administration; wound closure and dressing application; blood drawing 
for point of care testing such as blood coagulation timing and blood oximetry, and hemostasis via 
manual compression, external hemostatic device application, or internal hemostatic device 
insertion.

3.  MONITOR - Operates an interactive computerized digital subtraction angiographic system in order 
to produce coronary and left ventricular graphic images, and to perform pulmonary, aortic, and 
peripheral arterial imaging. Coordinates a delicate balance of radiographic techniques (x-ray 
factors), patient positioning, and computer assisted acquisition and display so as to provide 
optimal patient care in the cardiac catheterization laboratory. Enters patient data and 
acquisition/procedure parameters through the computer keyboard. Uses a variety of menu-driven 
programs to display, redisplay, and manipulate images in real time to allow physicians optimal 
visualization of anatomy so they may determine adequacy of procedure or interventions performed. 
Performs post-processing of images to include assessment of quantitative and qualitative coronary 
artery stenosis, left-ventricular volumes, left ventricular wall motion, presence or absence of 
abnormal communication between chambers and many other available programs. Stores data and images 
on one or more storage media (e.g., videotape, hard drive, compact disk, etc.). Reviews and/or 
records patient history and supporting clinical data before each of the procedures listed above. Uses 
electrophysiologic and angiographic monitors with interactive, menu-driven programs to enter 
patient data and acquisition/procedure parameters. Monitors hemodynamic values, wave forms, and pressure 
gradients and electrocardiogram tracings; differentiates normal from abnormal and informs the team of 
changes in patient status. Records anatomical, physiological, and/or pathological data for further 
diagnosis. Keeps record of procedures performed and related data. Processes automated and other 
records obtained during the procedure. Identifies, files, and stores records and retrieves them as 
needed. Operates and maintains equipment for viewing records. Initiates ACLS protocol as needed.

4. CIRCULATOR - Retrieves images for replay as well as the roadmap. Performs a replay review of images to 
include quantitative and qualitative assessment of artery stenosis; ventricular volume, ejection 
fraction, and wall motion; and valve area. Reviews finished cine recordings and suggests changes 
in x-ray techniques to obtain records of optimal quality while ensuring maximum safety. Responsible 
for all required daily maintenance and preventive maintenance of cine processing equipment. 
Identifies, files, and stores such records, including a complete record of all patient x-rays 
parameters. Operates, maintains, and stores projection, tape replay, and other equipment for viewing 
records. Attends to patient’s safety and comfort needs before, during, and after procedure. 
Positions the patient initially and as needed during the procedure to ensure patient comfort and 
optimal study results. Connects monitoring equipment and ensures proper function and data 
collection during procedure. Anticipates, locates and opens sterile/non-sterile supplies. Operates 
defibrillator and pacemaker generator as well as radiographic contrast injector, cardiac output, 
intravascular ultrasound, angiojet, atherectomy, rotablator, and intra-aortic balloon pump 
consoles. Monitors and ensures compliance with aseptic technique and radiation safety principles. 
Repositions monitors and equipment as x-ray table and image intensifier are moved. Performs 
point-of-care testing such as blood coagulation timing and blood oximetry. Monitors patient's 
response to intravenous sedation/analgesia medication administration. Maintains safe and clean lab 
environment during the procedure. Applies noninvasive cardiovascular techniques of 
electrocardiography (12-lead ECG) and assists with synchronized cardioversion and transcutaneous 
pacing. Transports patients. Provides technical and administrative support and advice to 
technicians, nurses, students and physicians regarding new supplies, equipment, and procedures. 
Develops procedural instructions to insure proper performance of procedures. Participates in 
policy/procedure review and revision process. Collects and compiles data for formal and informal 
research efforts. Maintains and calibrates equipment. Conducts quality control checks; performs 
corrective actions as needed. Assists in controlling and maintaining supply inventories. Cleans 
instruments and maintains sterile instrument inventory. Practices and promotes compliance with 
Infection Control, Radiation Protection, and Fire and Safety regulations. Supports
ACLS protocol as needed.
