2. Mobile radiography.
• Mobile x-ray unit used primarily for bedside radiography and may also
be used in the surgical suite.
• Study done with this equipment is generally termed as “portable
examination / portable x-ray”. But this is not very accurate term.
• Two types of unit are generally used : the mobile radiographic unit
and the C-arm mobile image intensifier ,a fluoroscopic unit.
• It is often more advantageous to perform bedside radiography for
patient in special care unit , orthopedic traction and isolation.
• Mobile radiography has some limitation compared to departmental
fixed X- ray unit.
4. Cont..
• Follow these guidelines:
• Check with the nurse in charge to inquire about patients condition.
• Confirm the order in the patient’s chart , if applicable .
• Always greet the patient (if applicable ) , check the name and D.O.B
and identification band.
• Inspect and prepare room before bringing x-ray machine .
5. Special Care Units
• Intensive care Unit (ICU)
• Coronary care Unit (CCU)
• Neonatal Intensive Care Unit (NICU)
• Post anesthesia Care Unit/ Recovery (PACU)
• Emergency Department (ED) /Trauma Unit
• High Dependency Unit (HDU).

7. Treatment Situations Involving specialty Equipment
Special Beds and Mattresses.
• Alternating pressure mattress / Rocking beds – needs to be turned
off during exposure to avoid motion artifacts .
• Air mattress – must be fully inflated to firm up and level the bed
before placing the IR under patient.
• Patient laying on an alcohol or water filled pad to raise or lower body
temperature , it is important to place IR on the top of the pad to avoid
artifacts.
• Must be careful while placing IR in between of patient and Mylar
warming blanket.

9. Orthopedic Traction.
• Don’t attempt to alter a patient’s traction.
• Sudden release of traction may result in serious harm.
• Don’t bump against bed.
• Take help of nursing staff.
• Encourage patient to co-operate and use Trapeze bar to raise patient's
torso.
12. Mechanical Ventilation:
• An endotracheal tube is passed through the mouth into the trachea.
• The tube is connected to ventilator.
• While performing radiograph don’t turn off ventilator to eliminate
respiratory motion.
• Pay attention to breathing rhythm .
• Sense the breathing rhythm correctly and keep short exposure.
• Position patient carefully without applying tension to tubing .
• If patient is in AMBU bag , instruct nursing staff to stop squeezing
while exposure is made.

14. Nasogastric and nasoenteric Tubes.
• Tubes passes through the nose and down into the stomach or small
intestine.
• Has several purpose as feeding , decompression , radiographic
examination.
• Levine and Salem-sump tubes are often sued.
• Don’t disturb the tube while taking radiograph .
• If it has to be disconnected from suction ,temporarily take permission
from the nurse.
• While giving oral contrast through tube make sure not to displace
tube from its location .
16. Closed chest Drainage.
• Used to remove air or fluid accumulated in the pleural space.
• While taking radiograph:
• Ensure that chest suction and drainage apparatus is not disturbed.
• Take care that the chest tube is not dislodged when positioning the IR
for the chest radiograph.
• Ensure that drainage unit remains below the level of the patient’s
chest .
17. Pacemaker :
• You should not elevate or abduct the patient’s left arm for 24 hours
after surgery to prevent dislodging the pacemaker and catheter.
18. Placement of central lines.
• Swan - Ganz catheter is correctly placed when its tip lies in the right
or left pulmonary artery. Catheter measure cardiac output and heart
pressure. Inserted through subclavian , jugular or femoral vein .
• Central venous catheter (CVC)- These is advanced into the venecava
through veins . It facilitate the administration of long term drugs,
dialysis ,blood transfusion , drawing blood and monitoring central
venous pressure.
• Make sure to position patient and tube correctly in order to show
correct placement of catheter in radiograph .
• Avoid patient rotation .
