Chapter 1: Introduction; Intended Use; Indications For Use - biodex PULMONEX II Operation Manual

1. Introduction

Intended Use

The Pulmonex II Xenon System was designed for the safe delivery and trapping of Xe-133 to a
patient. It is shielded for patient and operator safety. The design features are intended to provide
maximum, reliable test results.
Before using the Pulmonex II on an actual patient, we suggest making 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 will be able to perform xenon studies on any
patient with complete confidence.

Indications for Use

The Pulmonex II Xenon System is typically used in a nuclear medicine department, diagnostic
imaging centers and private practice clinics to achieve quality lung images.
Internal systems of the Pulmonex® II are shielded for patient and operator safety. The system
features two built-in gas traps that operate with a blower fan. Exhaled xenon is pulled through
activated charcoal housed within two .125" lead shielded "u"-shaped traps. The double traps
extend the life of your charcoal and provide a lengthy migration path for xenon effluent, allowing
greater decay and absorption before exhaustion. 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. Airflow regulation of the trap pump assures complete
patient and system washout. Averaging 30-50 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.
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.
