A common neonatal chest disorder requiring portable radiography in the neonatal unit is transient tachypnea of the newborn (TTN). Radiographs are taken to visualize the chest for respiratory distress, and in doing so, the imaging professional must
1. use the highest degree of aseptic techniques.
2. use lead protection when possible, and sterilize after each use.
3. surgically scrub your hands to replace gloves in order to position the neonate with better precision.
4. wrap all items that may have the potential of coming in contact with the newborn.
5. use contact or shadow shielding for patient protection.
6. treat the procedure as a sterile procedure similar to surgery.
