About this photograph
Exact discussed model: Carestation 620, visible on the photographed machine; accessories and monitor are the pictured configuration.
The decision at a glance.
- Start here
- Evaluate Gradian UAM where interrupted utilities shape the service, with its concentrator and ventilation maintenance funded. Compare Carestation 620 where dependable gases, power and GE support already exist.
- Spend more when
- Replace a supportable Aestiva when the new package removes an actual capability or continuity gap. Integra SP VSO2 fits repeated travel only after the complete ventilation, monitoring and gas kit is specified.
- Watch the budget
- UAM's published six-hour backup covers the ventilator and vital-sign monitor. Its concentrator needs mains power; room-air fallback does not preserve oxygen-enriched delivery. Fund backup oxygen separately.
- Check the support
- Require the exact power-loss behavior and applicable corrective-action record. Certain Carestation power boards have a documented battery-transfer correction; the model name alone cannot establish the offered unit's status.
Ask the supplier
- Which vaporizers, ventilation and monitoring functions are included?
- What operates after mains loss, and for how long?
- Who services the concentrator and the exact workstation at our hospital?
Start with the interruption the next machine must solve
List why planned operating sessions are interrupted before choosing a replacement. If oxygen delivery is unreliable, another conventional workstation may leave the main problem untouched. The UAM's integrated concentrator and monitored delivery make it relevant to that situation. If the hospital already has dependable gases and power, the stronger purchase may be a conventional system supported by the technicians who maintain the rest of the theatre.
Separate oxygen generation from ventilation backup. Gradian specifies six-hour batteries for the ventilator and vital-sign monitor, while the concentrator requires 220–240 V, 50–60 Hz power at 500 W. That supply is part of the site plan. Its room-air fallback does not preserve oxygen-enriched delivery: fund the appropriate backup oxygen source and the rest of the monitoring and power arrangements.
Use the existing Aestiva as a serious competitor
An accepted Aestiva can be the budget choice when its current capability is sufficient and the next likely repair is supportable. Put the cost of restoring and maintaining that exact machine beside the cost of installing a replacement. Include vaporizer service, sensors, battery condition and repair freight. Replacement earns its cost when it removes a recurring limit on service or an unsustainable repair dependency.
Fleet consistency also has value. A hospital with trained staff and compatible accessories should count what a platform change would require. A mixed collection of donated machines can create several separate parts and documentation problems. Older Narkomed, Fabius GS, Apollo, Aespire and Aisys units remain conditional assets to inspect; their present service eligibility was not established. The verified End of Sales page concerns the regional Fabius Tiro D-M specifically, not every Tiro variant.
A battery label is insufficient evidence of outage readiness
The FDA's December 2025 Carestation communication identifies certain power-management boards that can prevent automatic transfer to battery after AC loss. For a hospital experiencing outages, the specific board and manufacturer-directed corrective action belong in the acceptance record. The notice is an instruction correction, not a blanket instruction to remove every Carestation. A supplier should identify the offered unit's status before the buyer relies on its backup behavior.
An older machine needs the same precision. The historical Aestiva/5 recall concerned specified units and a missing vaporizer-interlock component; the recall is listed as terminated. It supplies a component-level check, not a verdict about every Aestiva's condition today. No comparable field failure data establish a durability winner across the shortlisted platforms.
Price the portable kit after packing it on paper
Integra SP VSO2 becomes interesting when the equipment must travel repeatedly. Before valuing its compact base, write out the full traveling kit: required ventilation, vaporizers, monitoring, circuits, gas supplies, connectors, cases and power arrangements. The base's 26-pound weight does not describe that complete system's weight or price.
For a permanent hospital, transporting a cart once is a different expense from carrying a kit between sites every week. Choose portability for the actual movement pattern. No current complete-system prices were verified here, so the recommendation rests on capability and installed requirements; the cheapest fully specified offer remains an unresolved local comparison.

Model notes, pricing & support 4 options
Gradian Universal Anesthesia Machine (UAM)
Infrastructure-adapted first choice
- Best for
- Hospitals where oxygen supply interruptions materially limit anesthesia services
- Why consider it
- The manufacturer documents an integrated concentrator, oxygen monitoring, and electrically driven ventilation with battery backup. That combination addresses an actual infrastructure expense that a cheap imported workstation can leave entirely to the purchaser.
- The trade-off
- The concentrator and ventilator add maintenance responsibilities. The published six-hour backup covers the ventilator and vital-sign monitor. The concentrator needs mains power; its 9 V battery powers the mains-failure alarm, not oxygen generation. Include a suitable backup oxygen source and check the package's intended patient range.
- Price & package
- Quote required as of 2026-10-16; request the machine, vaporizers, monitoring, installation, freight and local service as separate lines.
- Support
- Current manufacturer product and customer-support routes are published. Local technician coverage, response time and warranty applicability at the destination are not confirmed.
GE HealthCare Carestation 620
Conventional choice for an established OR
- Best for
- A fixed operating room with dependable gases, electricity and accessible GE service
- Why consider it
- Compact layout, guided checkout and modular respiratory monitoring make this a credible current alternative to repeatedly repairing an old donation. Evaluate the actual installed ventilation and monitoring configuration.
- The trade-off
- Its infrastructure and service assumptions differ from the UAM. A current FDA correction concerning certain Carestation power-management boards makes outage performance a specific acceptance issue.
- Price & package
- Quote required as of 2026-10-16; no verified public configured-system offer obtained.
- Support
- GE maintains a current product page and documentation. Obtain serial, board and corrective-action status plus an actual destination service agreement; a web page alone is not that agreement.
Avante Integra SP VSO2
For a complete traveling kit
- Best for
- A team with a documented transport requirement and a complete anesthesia infrastructure plan
- Why consider it
- Avante’s 2025 presentation describes a 26-pound tabletop unit with a vaporizer mount and carrying arrangements. Weight and packability can matter more than a cart’s unused options when equipment must travel repeatedly.
- The trade-off
- Do not treat a portable delivery base as including a ventilator, patient monitor, gas supplies or all required accessories. Comparing this base against a complete cart would distort the budget.
- Price & package
- Quote required as of 2026-10-16 for a specified human-use configuration and transport case.
- Support
- A current first-party product presentation was found. Repair geography, parts commitments and exact ventilator pairing are unconfirmed.
GE Aestiva/5 7900 SmartVent
Keep if already owned and serviceable
- Best for
- An existing standardized fleet with documented maintenance and a competent service partner
- Why consider it
- Avoiding replacement can be good value when the whole installed system passes acceptance and parts can actually be obtained. This is a condition-based recommendation, not a new claim of superior reliability.
- The trade-off
- Age, vaporizer condition, sensor replacement and repair freight may erase the apparent acquisition saving. An FDA recall identified particular units with a missing vaporizer-interlock component.
- Price & package
- Quote required as of 2026-10-16; no current complete refurbished offer verified here.
- Support
- The historical FDA notice is model-specific evidence, not proof of current manufacturer service. Written parts and service coverage remain required.
Budget for the complete service.
Cost per completed anesthesia case = (installed capital + gas infrastructure + monitoring + preventive maintenance + repairs/freight + consumables + backup provision) / completed cases over the chosen service period
- Vaporizer inspection and agent compatibility
- Gas supply, hoses, regulators and scavenging
- Oxygen sensors, flow sensors, absorbent and circuits
- Battery replacement and protected power
- Technician travel, loan equipment and international repair freight
