OSCA Goes Green with DGSS Installation

The Orthopaedic Surgery Center of Asheville, in cooperation with Metropolitan Medical, recently conducted a study of cost savings from the installation of three gas scavenger devices on their GE Aestiva 7100 anesthesia machines. The results were promising, projecting a 10-year cost savings of over $17,000 for us.

Metropolitan Medical installed the three Dynamic Gas Scavenger System (DGSS) devices on three GE Aestiva 7100 anesthesia machines in November 2012 at OSCA. The six-month cost analysis was focused on our vacuum pump, weighing several significant factors in determining the potential benefits of the new equipment.

The average daily usage of the vacuum pump prior to installation was 21.8 hours per day, or a total run time of 3,978.5 hours over a six-month span. After installation of the DGSS device, the average daily usage was reduced to 10.71 hours per day, or a total run time of 1,954 hours over a six-month span.

Pump run time was decreased by 2,025 hours, decreasing the facility’s electrical costs by a projected $1,117.31 per year. In addition, the vacuum pump service costs were reduced by an estimated $1,200 per year. The vacuum pump life was increased by an estimate of six years, also resulting in a capital cost savings for the facility. The total cost savings is projected to be $2,317.31 per year, or $17,673.10 over 10 years, considering total cost savings minus the low cost initial investment.

We purchased the DGSS scavenger devices after replacing their vacuum pumps in March 2011. Because the pumps were new, the equipment was determined to have good maintenance records. Costs and average usage records prior to installation of the DGSS were easily calculated.

We are excited to decrease energy use, promote a more favorable environmental impact, and reduce operational costs. The DGSS device is an essential first step towards anesthetic recycling and reducing greenhouse emissions.
