COMEN AX-900 Anaesthesia Workstation
COMEN AX-900 anaesthesia workstation with ascending bellows, electronic fresh-gas control, nine ventilation modes and an independent 8-inch flow-control touchscreen.
Product introduction
The COMEN AX-900 integrates an anaesthesia ventilator, respiratory monitoring functions and electronic fresh-gas control in a surgical workstation. Pneumatic components work with electronic and fluid control to support ventilation, respiratory parameter adjustment and monitoring throughout perioperative use.
Key features
Pneumatic drive and electronic control
Ascending bellows and a compact circuit support ventilation delivery and triggering during SIMV and PSV.
Perioperative ventilation
Four control modes, three SIMV modes and two pressure support modes are listed for different perioperative stages.
Closed-loop fresh-gas control
Direct oxygen-concentration setting with automatic adjustment of the oxygen-to-balance-gas ratio.
Dedicated flow-control display
An independent 8-inch LED touchscreen provides a separate fresh-gas operating area and flow information.
Ventilation technology and breathing circuit
Ascending bellows combine pneumatic drive with electronic control. The manufacturer describes a compact breathing circuit and a smaller loop cavity, with stable ventilation and responsive triggering during SIMV and PSV. It also states a higher compression capacity, without specifying a value or comparison basis.
PEEP supports clinician-directed lung protection and recruitment manoeuvres. The supplied figures are 7% ventilation accuracy and 65 ml/min leakage. These are reproduced as supplied, with no assumed ± tolerance or additional test conditions.
Perioperative ventilation modes
| Mode group | Number stated |
|---|---|
| Control ventilation | 4 |
| SIMV | 3 |
| Pressure support ventilation | 2 |
The source lists these three groups without identifying every individual mode. They are described for anaesthesia induction, maintenance, recovery and spontaneous breathing practice.
Advanced fresh-gas control system
Electronic closed-loop control allows the anaesthetist to set oxygen concentration directly. The system then adjusts the ratio of oxygen to balance gas. Real-time correction of oxygen concentration and total flow is designed to address flow errors associated with fluid inertia.
The Best Flow Indicator Tool displays the flow associated with current anaesthesia ventilation and supports consideration of low-flow anaesthesia. Its colour-spectrum diagram follows the manufacturer’s alarm-colour design to make the current flow value easier to interpret.
Control system and pressure indication
Fresh-gas control uses an independent 8-inch LED touchscreen, providing a separate operating area with detailed flow information. The source does not identify this screen as the main ventilation display.
An electronic gas-source pressure gauge provides pressure indication without a mechanical pointer. The manufacturer describes this as avoiding pointer inertia.
Product benefits and applications
- Separate fresh-gas controls provide a dedicated area for flow adjustment and observation.
- Respiratory monitoring and breathing-parameter adjustment support anaesthesia management during surgical procedures.
- Ventilation groups support induction, maintenance, recovery and spontaneous breathing practice.
- The Best Flow Indicator Tool supports fresh-gas usage assessment during low-flow anaesthesia.

Q: Saves time
A: This reason might be the most obvious, but it’s a clear benefit of an FAQ page. Not only does the FAQ page save customers time, but it also saves employees time as well. Having an FAQ page ensures customers don’t have to sit on the phone for hours waiting for simple answers, and employees don’t have to individually answer all questions.
Q: Earns trust
A: Information is available at the click of a button, but as we all know, information is not always true. Because of this, customers are more skeptical than ever before. They hunt for products by sifting through reviews, looking at the product on multiple websites, and doing price checking across the internet.
Q: Provides new insights
A: It’s difficult to get into the head of a shopper. Some buy on impulse, and others buy after thorough research. By tracking the clicks on your FAQ page, you can gather insights about your product or service that you didn’t know before. You can then inform your product team of these insights. From there, the product team can make changes to improve the product or experience.
Q: Drives internal page views
A: If you want your FAQ to be extremely thorough, which it should be, you can link to resources within your FAQ for your customers to find out more information. Whether you link to a blog that goes into more detail or a product page, this content helps the shoppers get the full story before making a purchase.
A: Prevents negative reviews
A: When looking through negative reviews, there’s almost always one thing in common: the problem could’ve been avoided.
