EXAMPLE 1

• PATIENT POSITION SUPINE

• C-ARM PLACED ON THE PATIENTS LEFT SIDE

• RR SETTING OFF = NO LIGHTS ON

• IMAGE APPEARS RIGHT SIDE UP (NOT UPSIDE DOWN) AND CAN BE ADJUSTED CLOCKWISE OR COUNTERCLOCKWISE.

• 

   

ORIENTATION INDICATOR LIGHTS OFF

• PATIENT PRONE POSITION

• C-ARM PLACED ON THE LEFT SIDE OF THE BED

• RR SETTING 1 LIGHT PRESSED (RIGHT RR LIGHT INDICATOR)

• COMMON EXAMPLE IS THE ERCP PROCEDURE

RIGHT RR INDICATOR

        C-ARM PLACED RT SIDE OF BED                                       

                            

                     PRONE POSITION

EXAMPLE 3

• PATIENT SUPINE POSITION

• C-ARM ON THE RIGHT SIDE OF THE BED (PATIENTS RIGHT)

   ORIENTATION (RR) BOTH LIGHT INDICATORS PRESSED 

            

                                                                                  PATIENT IN SUPINE POSITION

 C-ARM PLACED ON THE PATIENTS RIGHT SIDE         

CONCLUSION

$$$ EACH BRAND, MAKE AND MODEL OF C-ARM FLUOROSCOPY MACHINES MAY VARY IN DISPLAY FEATURES, AND THE LAYOUT OF THEIR CONTROL PANELS OR TOUCH SCREENS. TODAYS TIPS ARE JUST SOMETHING TO PASS ALONG FOR STUDENTS, NEW TECHS, OR ANYONE STRUGGLING TO HANG THE IMAGES PROPERLY DURING CERTAIN CASES. UNFORTUNATELY, THE C-ARM MAY BE SOMETHING THAT MANY STUDENTS GET THE LEAST TRAINING AND EXPERIENCE USING DURING CLINIC ROTATIONS DEPENDING ON THE STUDENT AND PROGRAM REQUIREMENTS. MANY RAD TECHS, MYSELF INCLUDED, LEARN THE C-ARM AND SURGICAL CASES ON THE JOB. I HAD TO FIGURE IT OUT ON MY OWN OR BY MISTAKES AND HELP FROM SURGEONS. I HEARD A LOT OF TALK ABOUT SMILEY FACE PLACEMENT ON THE GE OEC C-ARMS AND IT NEVER QUITE MADE SENSE TO ME. I HAD SEVERAL TECHS TRY TO EXPLAIN IMAGE ORIENTATION TO ME BUT COULD NEVER QUITE GRASP IT UNTIL I STARTED WORKING AT A SURGERY CENTER AFTER COLLEGE AND FINALLY GOT IT SORTED OUT. THANK GOODNESS. I HOPE MY EXPERIENCE HELPS SOME FOLKS ALONG THE WAY TOO. THANKS FOR YOUR INTEREST AND BEST WISHES ALWAYS. 

C-Arm Fluoroscopy X-ray Basic Start Up

Setting up the C-arm

1. Plan ahead to avoid difficulties during a case or procedure. Be sure to place the C-arm and the correct monitor in a proper position for patient access and a good field of view for all staff viewing images during a case. It is important to use a c-arm and a monitor that are paired for compatibility. Machines that are not matched properly may not perform properly or give error messages but more commonly the system will just fail to boot up and not operate. Match the machines properly to avoid start up issues. Remember to allow plenty of room for the C-arm operation and plan ahead by checking the operating room for a clear path free from obstacles that could interfere during a surgery case such as the base of the patient bed, arm board placement or a suction and Bovie machine blocking the path to the patient and the area of interest. Good preparation for machine and patient placement often will go hand in hand with a successful C-Arm case experience.

2. Once you have the correct machine and monitor in place, it is time to connect the cable and plug in the monitor to start up the C-arm machine. Most machine cables have connections that need to be lined up properly to connect. The cable couplings will often have red dots that line up to ensure proper connection dot to dot between the cable and the C-arm. Be careful not to twist or damage connecting parts. Once the C-arm is interconnected with the cable to the monitor, the monitor can be plugged in to a power source and the green start button can be pressed to boot up the system. The boot up process normally takes about three minutes or less depending on the brand and type of machine in operation. 


3. Most C-arm machines will be password enabled to ensure that only authorized users are able to access the C-arm X-ray machine. After the correct password is entered, a blank patient information screen will appear, and the machine is often ready for an exposure. Every software package is a little bit different but most of the tabs and commands are universal such as patient information, image directory, and special applications. 

4. Now that the system has booted up and is ready for operation, the C-Arm setting and patient information can be entered, adjusted, or edited. C-arm X-ray machines have exposure switches or buttons that allow the user to take a single image or go live for a series of X-ray images. The machines can offer a single button, or a remote hand control or foot pedal for exposure. The machine settings can normally be adjusted for image orientation and swap features, collimation, lower doses, and a save image to directory. Press the save button if you do take an image that you want to keep in the system directory. Once the image is saved, it can normally be sent to another computer system. Most c-arm monitor systems will keep images and patient study information for three months before recycling and purging memory.  Good luck getting the C-arm started and ready for operation. Remember that it takes lots of practice and experience to become confident and successful with anything. The key is to get started, learn while you are a student in clinicals and keep learning on the job. Learn from your mistakes and listen to others including the doctors, nurses, techs, and reps involved in the case or procedure.
