The Datex AS/3 anesthesia patient monitor is an excellent anesthesia monitor for the export markets. It uses the exact same modules as the more expensive Datex-Ohmeda S/5 and monitors the same functions, gases/agents.
The main difference between the Datex AS/3 and the more expensive Datex/Ohmeda S/5 is in esthetics. The S/5 is more modern looking and uses a flat screen other than that they are the same monitor. If you are looking for a full system anesthesia/patient monitor at an affordable price you should consider the Datex AS/3 Anesthesia monitor.
