7. Adjust height of assembly on stand for patient comfort. Explain
procedure to the patient. Place disposable gloves on the patient if
handling of the tubing will be required by the patient during the study.
8. Place the mouthpiece in the patient’s mouth. After ensuring the patient
maintains a good seal on the mouthpiece, apply the nose clip and
instruct the patient to relax and breathe deeply on the system several
times to ensure proper operation and familiarize the patient with the
system.
9. Connect one end of O
2
tubing to the O
2
supply and set the flow to
10-11 liters per minute. Confirm that the patient is ready to begin the
procedure. Connect the other end of the O
2
tubing to the Venti-Scan IV
inlet tube to start the aerosol delivery procedure. INSTRUCT THE
PATIENT TO CONTINUE BREATHING ON THE SYSTEM FOR THREE
TO FIVE MINUTES TO ENSURE SUFFICIENT LUNG DEPOSITION.
10. After allowing enough time to ensure sufficient lung deposition, turn
OFF the oxygen (or air). To maximize clearance of any remaining
activity in the tubing following inhalation, and to minimize the possibility
of inadvertent contamination to the patient and room, instruct the
patient to continue breathing for five or six breaths before removing the
mouthpiece (you may also instruct the patient to expectorate into a
disposable towel to be handled as normal radioactive waste).
11. Once the patient mouthpiece has been removed, remove the nose clip
and begin imaging.
NOTE:
Imaging may be performed during radioaerosol inhalation.
CAUTION:
To prevent inadvertent contamination of the patient or
room, use care and good radiation practice when removing the patient
from the system.
ATTENTION:
Pour éviter de contaminer le patient et la piece, suivre
les pratiques usuelles relatives aux rayons X lors de la sortie du patient
du système.
CAUTION:
This procedure may NOT be appropriate for uncooperative
patients or for patients who cannot maintain a good mouthpiece seal.
ATTENTION:
Cette technique peut ne pas être adaptée à des patients
non coopérants ou à des patients ne pouvant pas maintenir une bonne
étanchéité sur la pièce buccale.
12. Disconnect the oxygen tube. Remove the shield assembly from the IV
pole mount and transport to a radioactive waste disposal area.
