What’s an anesthesia machine got to do with… glacier melting?
To create a green operating room for healthcare workers, Mindray integrates a series of advanced tools into its anesthesia machines to help doctors optimize the management of fresh gas and anesthetics, and enhance the safety of the environment.
The fresh gas flow rates in the circuit can affect the amount of anesthetic agent used. Unless necessary, the low fresh gas flow rate should always be considered to reduce the WAGs, not only for safety reasons, but for cost reasons too. Statistics from the Department of Anesthesiology in the University of Nebraska Medical Center show that nearly a million dollars can be saved by lowering fresh gas flow rates for 4 years.
The grey area shows the recommended value range. The arrows indicate the current setting value, with different colors showing the status of fresh gas flow (green – efficient, yellow – high, red – low).
