Designed for lung ventilation scans.

The Pulmonex II Xenon System is the best choice for the performance of all regional ventilation studies. It’s safe, simple to operate and affordable.

Resistance-Free Breathing

The injected bolus of xenon will reach the patient exactly when desired. Oxygen may be added to the system any time during the study with the press of a button. An in-line cartridge containing soda-lime absorbs CO2 preventing acidosis. Large breathing passages, two 10-liter breathing bags (air-in and air-out) and motor-assisted air flow combine to provide resistance-free breathing.

Simple to Operate

All three steps of a Pulmonex II Xenon study (start up, equilibrium imaging and washout) are controlled by a single valve handle on the front panel. The valve directs the motor-assisted flow of gases throughout the system. A manually adjusted fifteen minute timer initiates all functions, then automatically shuts down the system to complete the study after patient and system washout. With controls conveniently located on the front panel, the user can operate the system and observe the patient and gamma camera from one position. Panel controls are clearly marked for each mode of the procedure with large viewing windows to make it easy to monitor the patient’s breathing. A trim, clean design, large handles and total mobility permit easy positioning of the system for studies in both seated and supine positions.

Designed for Safety

Internal systems of the Pulmonex II are shielded for patient and operator safety. The system features a built-in gas trap that operates with a blower fan. Exhaled xenon is pulled through activated charcoal housed within a .125" lead shielded “U”-shaped trap. A cartridge containing drierite serves as a moisture absorber for air passing into the trap. The charcoal trap can then more effectively remove xenon effluent after each study. Air flow regulation of the trap pump assures complete patient and system washout. Averaging 15 studies per month, the charcoal trap will last approximately one year. Charcoal traps are easily replaced.

A disposable bacteriostatic filter, used in conjunction with a disposable mask or mouthpiece, prevents system contamination.

Pulmonex II Xenon System with Double-Trap

For departments performing up to 15 xenon studies per month (upper dosage = 10-12 mCi), the Single-Trap Pulmonex II is ideal. For higher volume departments with more frequent xenon studies or higher dosages, the Double-Trap Pulmonex II is recommended. The double trap will extend the life of your charcoal system and provide double the migration path for xenon effluent, allowing greater decay and absorption before exhaustion.

The Pulmonex II Xenon System includes a sampling of disposables required to complete a xenon study. Disposables are packaged individually or in Xenon Convenience Kits. ( The Xenon Convenience Kits include everything needed for a single study, including pre-measured CO2 soda-lime absorber and drierite cartridges.)
