No
The description focuses on electronic control, microprocessor-based systems, and user input for gas mixing and ventilation, without mentioning AI or ML algorithms for decision-making or analysis.
Yes
The device is described as an "Anesthesia System" that provides "general inhalation anesthesia and ventilatory support" to patients, which directly constitutes therapeutic intervention.
No
This device is an anesthesia system and ventilator. While it includes monitoring functions for patient parameters, its primary purpose is therapeutic (delivering anesthesia and ventilatory support), not diagnostic (identifying or characterizing a disease or condition). The built-in monitoring serves to ensure safe and effective delivery of the therapy.
No
The device description clearly details numerous hardware components including gas mixing systems, flow tubes, vaporizers, ventilators, displays, and physical frames. While it mentions software control and validation, it is fundamentally a hardware-based anesthesia delivery system.
Based on the provided text, the GE Datex-Ohmeda Aisys Anesthesia System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "provide general inhalation anesthesia and ventilatory support to a wide range of patients." This describes a device used directly on a patient for medical treatment and support, not for testing samples taken from the body.
- Device Description: The description details how the device delivers gases and anesthetic agents to the patient, provides ventilation, and monitors physiological parameters like inspired oxygen, airway pressure, and exhaled volume. These are all functions performed in vivo (within the living body).
- Lack of IVD Characteristics: The text does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.) outside of the body, which is the defining characteristic of an IVD.
While the device can integrate with modules that perform respiratory gas monitoring (like the M-Gas Module and E-Gas Module), these modules are monitoring gases within the patient's breathing circuit, not analyzing samples taken from the patient.
Therefore, the GE Datex-Ohmeda Aisys Anesthesia System is a medical device used for anesthesia and ventilation, not an IVD.

Device Description
The GE Datex-Ohmeda Aisys is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. It represents one of the systems in a long line of products based on the Datex-Ohmeda Excel, Aestiva, Aespire, and Avance Anesthesia Systems. It is to be used only by trained and qualified medical professionals.
The GE Datex-Ohmeda Aisys Carestation supplies set flows of medical gases to the breathing system using electronic gas mixing. Gas flows are selected by the user using the keypad and rotary controller on the main display unit and then displayed as electronic flow indicators on the system display unit. The Aisys is equipped with a pneumatic back-up O2 delivery system and traditional flow tube, as well. A large selection of frames, gases, and vaporizers are available to give the user control of the system configuration. The Aisys is also available in a pendant model. It is available with two or three gases, and up to three cylinder connections. All models have O2. The Aisys comes with up to two optional gases (air, N2O). Safety features and devices within the Aisys are designed to decrease the risk of hypoxic mixtures and complete power or sudden gas supply failures. The Aisys system is available with optional integrated respiratory gas monitoring. When supplied as an option, the integrated respiratory gas monitoring is provided via the Datex-Ohmeda M-Gas Module (M-CAiO and M-CAiOV software revision 3.2 and above K# 001814) and E-Gas Module (E-CAiOVX cleared via K051092) which can be physically intecrated into the Aisys, receive electronic power from the Aisys and communicate measured values to the Aisys for display on the system display unit.
The anesthetic agent delivery for the Aisys is controlled via an anesthesia computer through user input from the central display. The vaporization technology is based upon the electronic vaporizer cleared as part of the Datex-Ohmeda Anesthesia Delivery Unit (ADU) cleared via K973985. An Aladin cassette (also cleared as part of K973895) or Aladin 2 is inserted into the active cassette bay. The cassette holds the agent to be delivered - Halothane, Enflurane, Isoflurane. Desflurane or Sevoflurane. Agent is delivered as a percent volume/volume. The Aisys is designed to allow only one active cassette at a time. Per the user input into the main display, valves within the active cassette bay will open and allow agent to be delivered. The agent is mixed with gas from the FGC unit. After mixing, the combination of gases and agent is delivered to the breathing system and then onto the patient.
The Datex-Ohmeda 7900 Anesthesia Ventilator is used in the Aisys Anesthesia System. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber, bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple and secure setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is requlated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices. Ventilator modes for the device include Volume Mode, Pressure Control Mode, Pressure Support with Apnea Backup Mode (Optional) and Synchronized Intermittent Mandatory Ventilation (SIMV) Mode (Optional). Ventilator parameters and measurements are displayed on the system display unit.
The system display unit is mounted to an arm on the top shelf of the Aisys. The arm is counter balanced and capable of moving vertically and/or horizontally, and also tilting the display, enabling the user to position the display to the most advantageous viewing position. The arm length is limited such that the display position is always within the footprint of the Aisys frame. The arm also supports the mounting of additional display units for a variety of patient monitors.
Several frame configurations are available, including one that allows for the physical integration of the Datex-Ohmeda S/5 Anesthesia Monitor (most recently cleared via K030812). This configuration also provides cable management solutions such that the necessary connections from the monitor display unit to the monitor are hidden within the Aisys frame. An additional ootion allows the S/5 AM to be linked to the power supply of the Aisys such that when the Aisys is turned on, the S/5 AM is also turned on. Additional configurations allow for the mounting of various patient monitors on the top shelf of the Aisys.

INTENDED USE as required by 807.92(a)(5)
The GE Datex-Ohmeda Aisys Anesthesia System is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. The device is intended for volume or pressure control ventilation. The Aisys is not suitable for use in a MRI environment.
SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF DEVICE COMPARED TO THE PREDICATE DEVICE as required by 807.92(a)(6)
The GE Datex-Ohmeda Aisys has been updated from the predicate version (K073707). There have been no changes to the intended use or fundamental scientific technology.
The software for the Aisys has been updated to introduce several new features. A summary of the changes to the software include:
- Alarm Improvements . Improvements are made to the alarms to reduce nuisance alarms. ◆ These changes are the same as have been implemented in Avance 6.0 (K081844). The Vaporizer failure hardware alarm was improved to match the functionality of the existing Aisys Mixer hardware alarm. An audio alarm was added to the current Alternate O2 Button Pressed video message.
- User Configurations. Addition of more default configurations. .
- Usability Improvements Waves/Pages. The system will have more screen configurability . for waveforms and the numerics.
- . Checkout Improvements. Low pressure leak check, breathing circuit leak check, system check flow sensor and agent delivery checkout tests were enhanced.
- MAC Age. The mathematical calculation for MAC will now be able to be made ◆ accounting for the patient age. This is the same as is displayed on the S/5 Anesthesia Monitor (K030812, K051400).
- . Vaporizer Settings. To aid the filling process the system defaults to automatically depressurize the vaporizer cassette when the agent is turned off.
- Preset ventilator settings based on patient weight for PCV-VG mode. The preset . ventilator settings at the start of a case can now be based on patient weight for PCV-VG mode, similar to the way preset vent settings can be been based on patient weight for VCV mode in the previous Aisys.
- . Auto exit PSVPro backup mode. The system will now automatically exit SIMV-PC vent mode upon recognition of spontaneous breathing and resume PSVPro™ when patient resumes spontaneous breathing (change was previously made manually).
- . Calibrate flow sensors reminder. An informational alarm message will appear when the system is not in therapy between cases to remind the user to calibrate the flow sensors if flows sensors have not been calibrated for 24 hours. Currently the manuals give this instruction.
