n. Extract the desired volume of RP and remove the syringe. Assay the syringe in a
separate Dose Calibrator before injection.
o. Clean the Swabbable Valve and repeat steps m and n as necessary.
PAS Occlusion Recovery This section describes how to identify a potential occlusion and details the method to recover
from an occluded PAS during an infusion.
1. At the end of the infusion, if more than 5% of the dose activity remains in the Dose
Calibrator, the system will allow the user to resume the infusion or discard the dose.
MEDRAD recommends that the user check the lines for occlusions (clamped tubing,
kinked crushed tubing, or high-gauge needles or catheters, closed valves between the
PAS and the patient) prior to resuming.
WARNING: Radiation exposure hazard.
18
F-FDG or
18
F-NaF emit gamma
radiation. Operator should exercise extreme caution when handling
radiopharmaceuticals. Doses may exceed maximum permissible dose if appropriate
precautions are not properly exercised. Follow all individual facility guidelines for the
handling and disposal of radioactive materials. DO NOT open the Shielded Chamber
without first taking radiation precautions per facility procedures.
NOTE: During PAS Occlusion Recovery, the system will allow the clinician to attempt to
infuse the remaining RP a total of 4 times. If the activity remains in the Dose
Calibrator following 4 attempts to infuse, the RP will be discarded.
WARNING: In case of occlusion, do not disconnect disposables before
discarding dose, as liquid leakage can occur.
