Leak Test - biodex PULMONEX II Operation Manual

Leak Test

The following procedures are a simple yet effective means of testing the delivery and breathing
portion of the Pulmonex II system 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 hoses and
fittings.
If a Leak is Suspected
Remove the four screws that hold the front panel in and raise the panel slightly. Now feel inside
for any leaks.
If a Leak is Found in a Hose
Replace the entire section. Occasionally one of the breathing bags will tear or a hole will de-
velop. 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.
NOTE: If you suspect a leak but it is proving hard to find, move on to test B.
Test B
(Turn Pulmonex ON.)
1. 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 "To Patient" bag blows up, very carefully check to see if the fitting connecting the
blower to the blue adapter on 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, repeat the leak test (Test A).
7. If the bag fills, call Biodex Medical Systems to replace the10-way valve (catalog #132-515).
Test C Oxygen Button Valve Leak Test
(Be sure Pulmonex is turned OFF.)
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.
