INTRODUCTION
The combination of manual and electronic controls make the Pulmonex II Xenon Single and Double-Cartridge Systems the easi-
est units to use for regional ventilation studies. All internal circuitry, valves and tubing have been designed to afford simple oper-
ation with complete patient comfort. The result is a system that provides maximum, reliable test results with minimal effort.
For departments performing up to 15 Xenon studies per month (upper dosage = 10 - 12 mCi), the Single-Cartridge Pulmonex II
is ideal. For higher volume departments with more frequent Xenon studies or higher dosages, the Double-Cartridge Pulmonex II
is recommended. The Double-Cartridge system provides a longer migration path for the Xenon effluent, allowing greater decay
and absorption before exhaustion.
Before using either Pulmonex II system on an actual patient, we suggest you first make several dry runs through the following
operation procedures (without using Xenon). Having become familiar with the operating routine, ask a colleague to stand-in as a
practice patient and try the procedures again. Once you feel fully comfortable operating the Pulmonex II, you’ll be able to per-
form Xenon studies on any patient with complete confidence.
NOTE: Because the Pulmonex II uses a temperature-sensitive valve which must acclimate to the immediate environment, the
system must reside for several hours in the department where it will be used prior to performing any studies.
NOTE: The following symbol on your Biodex Pulmonex II System corresponds to this Operation Manual.

SET-UP PROCEDURE
(See Figures 1 - 3.)
1. Open lower front door. All hoses should be connected to their respective ports. (See Figure 1.)
2. Open the top door. The Pulmonex can use either of two different style Drierite cartridges. A
refillable plastic cartridge is shipped with your unit, it is located on the right side of the com-
partment. You can fill this cartridge to one-third full with loose Drierite (catalog #139-101).
Alternatively, you can remove this cartridge and replace it with the sample pre-filled single use
cartridge included in the sample Xenon Disposable Convenience Kit supplied. In either case,
the disposable blue Drierite cartridge prolongs charcoal trap life span. Failure to change the
moisture absorber regularly will significantly shorten the life span of the charcoal trap, there-
fore, it is recommended that you change it after every study. (See Figure 2.)
3. Located on the left side of the top compartment is the Soda-Lime cartridge. This cartridge
serves as a carbon dioxide trap. You can fill this cartridge to one-third full with loose Soda-
Lime (catalog #130-019). Alternatively, you can remove this cartridge and replace it with the
sample white pre-filled single use cartridge included in the sample Xenon Disposable
Convenience Kit supplied. In either case, the Soda-Lime cartridge helps stop the breakdown
of Soda-Lime granules that may possibly clog the 10-way valve and hinder patient air flow.
Failure to change the Soda-Lime regularly could cause the patient to hyperventilate, there-
fore, it is recommended that you change it after every study.
NOTE: The flow arrow on the pre-filled Soda-Lime cartridge should match the flow label in
the Pulmonex II cabinet.
4. Bring the unit to the area of operation. Ensure the Power Switch is OFF and the timer is on
"0". Plug into a near by electrical outlet.
5. At the rear of the unit, there are two black hose connections positioned side by side. (See
Figure 3.) The blue hose adapters in the open ends of hoses should be removed to connect
to these fittings. The blue adapters are required to connect to the Hans Rudolph Valve and to
old Pulmonex only.Attach the 1.125" bore hose and Hans Rudolph Valve assembly to the
hose connectors so that air flows into the Hans Rudolph Valve on the left and out from the
Hans Rudolph Valve on the right. Connect the bacteria filter directly to the Hans Rudolph
Valve. Attach either a face mask or mouthpiece directly to the bacteria filter.
NOTE: Keep the breathing tubes as short as possible. (See "Trouble-shooting" Strong Breathing
Resistance.) For supine patients, bring the system as close as possible to the bedside.
As a safety precaution you can connect a hose from your room vent to the exhaust port locat-
ed just below the overhang on the patient side of the Pulmonex II.
CAUTION: Some patients are sensitive to Oxygen. Consult a physician before using
Oxygen. If the physician prefers, substitute room air for Oxygen.
ATTENTION: Certains patients réagissent à l’oxygène. Se référer à un médecin avant
d’utiliser de l’oxygène. Utiliser l’air ambiant quand indiqué.
6. To add Oxygen, connect and clamp a .25" Oxygen hose from your supply to the Oxygen inlet
port on the Pulmonex II front panel.
CAUTION: Do NOT use humidified Oxygen.
ATTENTION: Ne pas utiliser d’oxygène contenant de la vapeur d’eau.
7. Ensure that the shipping cap is removed from the exhaust port located on the lower cabinet
on the rear of the unit (facing the patient).

PERFORMING A STUDY
(See Figure 4.)
NOTE: Oxygen input should not exceed eight psi. Oxygen input flow rate should be six to eight litters/minute not to exceed
50 liters/minute.
1. Using a source, position the patient in front of the scintillation camera. Ensure both lungs are within the crystal area.
2. Set the camera for Xe-133. Record all data on tape.
3. Turn the Power Switch, located on the patient side of the unit, to ON. (0 is OFF, 1 is ON.)
NOTE: Even after the Power Switch is set to the ON position, power will not be evident until the Timer has been turned ON.
4. Place the Pulmonex II as close to the patient as possible and set the handle to the “Start” position.
5. Set “Patient Air Flow” control to 30 (an arbitrary figure that can be changed to accommodate the patient’s breathing pattern).
6. Press the button on the front panel to add Oxygen to the “To Patient” bag. Only add a small amount of Oxygen, about one
quarter full. (The bag will only move slightly, do not fill it up.) More Oxygen can be added later if it is required for the patient.
In many cases, it is possible not to add any Oxygen and perform the entire study on ambient air.In all cases, the Oxygen is
only to enrich the air in the circuit.
NOTE: Toperform a study using ambient air,turn the Pulmonex II ON using the timer and proceed to handle position #2 before
connecting the patient to the system. When the “To Patient” bag is one-quarter full, switch the handle back to position #1. To add
ambient air, turn the Air Flow up to 100, add the desired volume, and turn the Air flow back to 30. The system is now ready to use.
7. Make sure the system is in position #1.
8. Set the timer to nine minutes (an arbitrary figure that can be changed at any time depending on the study procedure you prefer).
9. Place the face mask over the patient’s face and attach mask retainer or mouthpiece and nose clip. Place a Vertex Cape on
the patient.
10. With the handle in the “Start” position. Instruct patient to breathe briefly while becoming accustomed to the face mask. The
“From Patient” bag will move slightly as the patient exhales.

11. Switch the handle to single breath, "Equilibrium" position #2. Use either the DuPont Calidose Gun or a syringe filled with
Xenon, and puncture the injection site of the face mask or mouthpiece. Add the Xenon as you have the patient take a deep
breath. Instruct patient to hold breath for as long as possible. After exhaling the patient should resume normal breathing
while you increase the “Patient Air Flow” control to 50 (an arbitrary figure that can be changed to accommodate the
patient’s breathing pattern).
Advise the patient to breathe normally. Observe breathing bags moving through the front panel windows. Add Oxygen if
necessary for patient comfort.
NOTE: If the Xenon is not getting to the patient for single breath, on future studies lower the “Patient Air Flow” control to 10
or 20 for approximately five seconds before Xenon administration. Instruct the patient to exhale and add the Xenon while
the patient inhales.
12. Once the patient reaches equilibrium (one to two minutes, the counting rate on the camera stabilizes), switch to “Washout,”
position #3. Take washout data on the camera (typical framing: first picture, 15 seconds; second, 30 seconds; third, 60 sec-
onds). Have the patient breathe normally.
13. Carefully watch the “From Patient” bag. If it starts blowing up, the patient is breathing too fast. Advise normalized breathing
and increase the “Patient Air Flow” speed. If the bag continues to expand up towards the glass, the patient will feel back
pressure and resistance. To relieve this effect, increase “Trap Air Flow” by turning the Trap Flow knob clockwise until the
breathing bag deflates. Return the control to approximately one-half of its range when the study is complete. The use of this
trap motor control will be a rare occurrence. Do not adjust unless absolutely necessary and be sure to return it to its original
position. To be effective, the increase in motor speed must be accomplished before the bag is full, thus, it is vital to watch
the “From Patient” bag carefully during washout.
NOTE: If the motors are running too fast it may be difficult for the patient to breath in.
14. When the washout is complete, remove the patient from the system. Allow the system to run for a few more seconds or
until both bags are empty.
-7- PERFORMING A STUDY

MAINTENANCE
General Maintenance Procedures
1. Change the moisture absorber and the soda-lime (CO2absorber) after every study. If you wait until the granules change
color, efficiency is already greatly reduced. Absorber granules can also break down in size and the smaller granules and
powder clog the system, hinder patient air flow and damage system circuitry. Refillable cartridges (#132-555) are available.
2. Administer the Xenon as close to the patient as possible. Having the Xenon enter the patient near the face mask or mouth-
piece ensures a good bolus for single breath. We recommend using an injection adapter as close to the patient as possible.
Biodex carries an entire line of disposable Xenon circuits, some with injection adapters, with luer lock fittings, or injection
ports (see catalog). These options will allow the use of a Xenon gun, Xenon injection dispenser or syringe directly in line
with the patient’s breathing passage.
3. Test the trap effluent on a regular basis. Keep a formal record according to NRC regulations. The easiest and most efficient
way to test the trap is by using the Xenon Trap Monitor (catalog #136-752). If you do not have a monitor, refer to the Leak
and Trap Test procedure explained later in this chapter.
4. Periodically remove the two breathing tubes from the back of the unit. Take one tube and connect it to both ports, forming a
Cconfiguration. Place the handle in position #2 and press the Oxygen button until the bags are full and tight up against the
glass windows. They should remain full for approximately two minutes. If they sag or fail to blow up tight, the system may
have a leak. Refer to the Leak and Trap Test procedure as explained later in this manual.
Maximizing Charcoal Trap Efficiency
It is recommended that the Charcoal (catalog #132-319) be replaced once every 12 months. Tomaximize trap effectiveness fol-
low these guidelines:
1. After the patient has completed the washout, do not leave the system running for more than ten seconds.
2. Monitor the lower blower motor. It should be set at a maximum of 50-60 and only increased when a patient needs assis-
tance during washout.
3. Change the moisture absorber after every study!
NOTE: Do not leave the Pulmonex II in position #3 when not in use.

Leak Test
The following procedures are a simple yet effective means of testing the delivery and breathing portion of the Pulmonex II sys-
tem for leaks. Tests A and C should be done with the Pulmonex II turned OFF.
Test A: (Be sure Pulmonex is turned OFF).
1.Connect one hose between the “To Patient” port and the “From Patient” port located on the patient side of the system.
2. With the system in position #2 and the Oxygen supply connected, depress the “Add Oxygen” button on the front panel of the
system and fill until both bags are full and pressed up against the front viewing windows.
3.Turn OFF the Oxygen supply. Listen carefully for any leaks (the bags should remain full for at least one minute.) If no leak is
found, empty the bags, and replace outside tubing.
4. If a leak is suspected, remove the eight screws that hold the front panel in and raise the panel slightly. Now feel inside for
any leaks.
5. If a leak is found in the tubing, replace the entire section. Occasionally, one of the breathing bags will tear or a hole will
develop in it. These bags are Biodex Medical Systems (catalog #130-610 and are easily replaced. If the leak is in one of the
fittings, they can be easily sealed with silicone.
6. If you suspect a leak but it is proving hard to find, move on to test B.
Test B:
1. Turn Pulmonex ON.
2. Connect one hose between the “To Patient” port and the “From Patient” port located on the patient side of the system.
2. Empty both bags by putting into position #3.
3. Put system in position #1.
4. If the “ToPatient” bag blows up, very carefully check to see if the big fitting connecting the blower to the 10-way valve is
broken.
5. If it is, run a bead of silicone around the fitting to seal it and let dry.
6. Now try steps #2 through #4 again. If the bag does not fill, do a leak test again (Test A).
7. If the bag fills, call Biodex Medical Systems. The 10-way valve probably needs to be replaced (catalog #132-515).
Test C – Oxygen Button Valve Leak Test:
1. With a hose connecting the two patient ports, connect the Oxygen supply and turn it ON.
2. If the “To Patient” bag fills without depressing the “Add Oxygen” button, this valve needs to be replaced.
Pulmonex II Tubing Set-Up
Proper Pulmonex II tubing set-up is as follows: tubing, then Hans Rudolph Valve, then bacteria filter, and then the face mask or
mouthpiece placed directly onto the filter. You may add an injection adapter between the filter and mask or mouthpiece. The
solid plug or luer lock plug in the Hans Rudolph Valve should be pointing up. The Hans Rudolph Valve should flow in on the left
and out on the right.
NOTE: Please remember, if you have any questions or problems, contact our Service Department at 1 [phone].
MAINTENANCE -12-

Manual Trap Test (Without Monitor)
Trap exhaust is monitored by using the gamma camera without a collimator. The following simple technique is used:
1. Remove the collimator from the camera.
2.With a five percent window, calibrate for Xe-133.
3. Fill a large plastic bag with a known volume of air (typically, 50 liters).
4. Inject a known quantity of Xe-133 (such as 100
µ Ci) into the bag. The concentration will be 2 x 10-3 µ Ci/cm3.
5.Place the bag in front of the crystal and count for a known period of time. The c/m obtained is a measure of the efficiency.
6. Collect the exhaust of a typical study in another bag of the same volume (50 liters) and count as defined in step #5.
7. Ratio the count rates to the standard taken to determine exhaust concentration.
NOTE: Trap flow rate must be measured on site using a flow meter due to variables such as tubing length, blower speed, trap
condition, etc.
Example:
-13- MAINTENANCE
If 2 x 10-3 µCi/cm3yields 600,000 c/m above the background and collected effluent
from the patient study was 150 c/m above the background, then:
Ratio = 1.5 x 102c/m =2.5 x 10-4
6x105c/m
Exhaust Concentration = r (2 x 10-3 µCi/cm3
=(2.5 x 10-4)(2 x 10-3 µCi/cm3)
=5 x 10-7 µCi/cm3
*MPC Xe-133 controlled areas should not exceed 1 x 10-5 µCi/cm3
