Aisys™ CS² End-tidal Control software

Designed to complement the expertise of anesthesia providers in managing complex cases in the operating room, End-tidal Control (Et Control) software* for the Aisys CS² anesthesia machine allows anesthesia providers to set targets for end-tidal oxygen (EtO2) and anesthetic agent (EtAA). Et Control automatically adjusts fresh gas concentrations to quickly achieve and maintain those targets, regardless of changes in the patient's hemodynamic and metabolic status.

Benefits of End-tidal Control


Clinically safe

When used as indicated, Et Control is as clinically safe as manual fresh gas control1

Fast low-flow control

Reach 90% of your target within 90 seconds3 and maintain targets and minimal flow rates

Reduced workloads

Can reduce the number of key presses by up to 50%4 to help simplify adoption of low-flow strategies by your staff

Vigilant patient support

Et Control is twice as accurate in maintaining targets, regardless of patient status1

Eco-friendly practices

One study has shown a potential 44% decline in the rate of greenhouse emissions5 when employing Et Control software

Improved cost savings

Can reduce anesthetic agent consumption by over 25%1,4
