Metropolitan Medical partners with AGR to offer eco-friendly alternative to traditional anesthesia scavenging systems

Metropolitan Medical Services is partnering with Anesthetic Gas Reclamation(AGR) to offer the DGSS, an innovative new dynamic gas scavenging system designed to reduce energy and operating costs while helping reduce the anesthesia machine's impact on the environment.

Asheville, NC. July 13, 2011 Metropolitan Medical Services — a premiere anesthesia sales and service supplier — is now partnered with AGR to offer an innovative new scavenging system to replace traditional active scavenger interface systems, designed to reduce energy usage and operating costs while significantly increasing the vacuum pump life.

Dynamic Gas Scavenging SystemThe Dynamic Gas Scavenging System (DGSS®) is a waste anesthetic gas scavenger interface that is designed to quickly and easily attach to any anesthesia machine, including GE, Drager and Spacelabs models. The major benefits of the device include a reduction in scavenging energy and maintenance costs of up to 90%. In addition, the device is intended to greatly increase the efficiency of the anesthesia machine, significantly increasing the vacuum pump's life while eliminating the need to disconnect the scavenging vacuum at the end of the day. Perhaps the most important benefit of the DGSS® is its critical role in reducing greenhouse emissions.

Using general anesthesia, carbon compounds such as Isoflurane, Sevoflurane, and Desflurane are inhaled to produce general anesthesia for surgery. These potent greenhouse gases are currently exhausted into the environment outside the hospital or surgical facility. While the atmospheric effects of these discarded halogenated anesthetics don’t include ozone depletion, they do contribute to the production of acid rain and greenhouse effects, potentially aggravating global warming.

In the U.S. alone, the total production of these emissions amount to an estimated 2,000 tons per year – the equivalent of almost 4,000,000 tons of excess CO2 release. The EPA (and other international environmental agencies) have systematically regulated or banned many HFCs and HFC-like compounds. State and federal legislation controlling the release of halogenated anesthetics is expected in the near future.

Anesthetic Gas Reclamation, manufacturer of the DGSS®, intends to reduce these impacts and save energy in the process. Its scavenging system is the first step of three components in its anesthetic gas recycling system. The next component (recapture) is expected to be available late this year, while the third (reuse) should receive FDA approval in the near future.

Dr. James Berry, CEO of Anesthetic Gas Reclamation, is optimistic, “It is a rare opportunity to both help protect the environment and reduce healthcare costs.”
