Proprietary technology dries or humidifies medical gas and breath sample streams
Toms River, NJ (May 5, 2008) – Leading gas conditioning products manufacturer Perma Pure has been named a Best in Class Supplier by Cardinal Health (formerly Viasys Healthcare) for its ME™-Series moisture exchangers, used in Cardinal Health’s diagnostic and critical care respiratory care products. 

The ME™-Series’ proprietary technology dries or humidifies medical gas and breath sample streams without altering gas composition in breath sample dryers, filters and sample lines.  The antibacterial membrane tubing does not require power input for operation and there are no moving parts to fail.  Cardinal chose Perma Pure for the Best in Class rating based on the company’s ability to meet on-time delivery and quality standards, including stringent specifications for leak tightness.  The company was one of 12 vendors chosen for the honor from a field of over 500 Cardinal suppliers.

Moisture removal is a critical step prior to analysis in anesthesia monitoring, neonatal monitoring, asthma and respiratory care, metabolic testing, and capnography.  Excess water can block sample lines, damage analyzers and reduce the accuracy of analysis.  In supplemental oxygen systems, extremely dry breathing gases can cause patient discomfort. 

In either drying or humidifying applications, the ME-Series products seek equilibrium with room humidity, transferring water vapor into or out of the tubing in a stable, self-regenerating cycle.  Very low dead volume in the tubing eliminates drops in pressure.  With levels of humidification only reaching ambient conditions, there is no threat of rainout in the sample lines.  Unlike alternative technologies such as traps and filters, ME-Series products do not require regular monitoring and replacement.
