The GE Carestation 620/650/650c anesthesia machines (Carestation 600 series) are intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients (pediatric and adult). The anesthesia systems are suitable for use in a patient environment such as hospitals, surgical centers, or clinics. They represent one of the svstems in a long line of products based on the Datex-Ohmeda Aestiva (K000706). Aespire View (K122445) and Avance CS2 (K131945) Anesthesia Systems. The Carestation 600 series anesthesia systems are intended to be operated by a clinician qualified in the administration of general anesthesia.

The Carestation 600 series anesthesia systems supply set flows of medical gases to the breathing system using needle valve flow controlled gas mixing (O2 with Air, O2 with N2O, or O2 with Air and N2O). Gas flows are adjusted by the user using needle valve control knobs on the main system frame, the flows are displayed on the system display unit as numerical digits and as electronic representations of flow meters. Some models (Carestation 650, 650c) also display the flow digits directly above the flow controls. Carestation 600 series systems are also equipped with an integrated pneumatic flow tube that indicates total mixed gas flow from the 2 or 3 needle valves in the gas mixer (prior to the vaporizer manifold). The Carestation 650/650c systems provide an option for auxiliary mixed Oxygen + Air flow delivery where O2 with Air are blended and delivered to an auxiliary port used to support spontaneously breathing patients using a nasal cannula. An optional auxiliary O2 supply includes a separate O2 flow tube and needle valve flow control that delivers O2 flow to an auxiliary port used to support spontaneously breathing patients using a nasal cannula. The gas flow from the optional auxiliary O2 subsystem does not flow through the total flow tube. An optional auxiliary common gas outlet (ACGO) allows the clinician to direct the fresh gas flow of O2. Air, N2O, or anesthetic agent, through the ACGO port on the front of the system. The ACGO may be used to provide fresh gas to an auxiliary manual breathing circuit.

A large selection of frame options include central brake (Carestation 650) or individual caster brakes (Carestation 620), up to 3 breathing gases, optional storage drawers, and vaporizers are available to give the user control of the system configuration. The Carestation 600 series systems are also available in pendant and wall mount (Carestation 650c) models. All Carestation 600 series models have O2 gas and come with one or two additional gases (Air, N2O, or both). Carestation 600 series systems include two vaporizer positions and are available with up to three back-up gas cylinder connections.

The system uses touchscreen technology, hard keys, and a ComWheel to access system functions, menus, and settings on a 15" color display. The display is mounted on an arm on the left side of the machine. It can be rotated via the arm toward, or away from, the system to adjust the horizontal position. An optional arm is available allowing it to be tilted up or down to adjust the vertical viewing angle, or be moved left or right to adjust the horizontal position of the display. The split screen field can be set to show gas trends, Spirometry loops, airway pressure (Paw) gauge, airway compliance, and optional ecoFLOW information. If none is selected, the waveforms expand to fill the split screen area.

The Carestation 600 series systems accept Tec 6 Plus and Tec 7 vaporizers on a 2position Selectatec vaporizer manifold in the same way the Aestiva, Aespire View and Avance CS2 machines use the Tec 6 Plus or Tec 7 vaporizers. Features and devices within the Carestation 600 series systems are designed to decrease the risk of hypoxic mixtures, multiple anesthetic agent mixtures, complete power failure, or sudden gas supply failures. The Carestation 600 series systems are available with optional integrated respiratory gas monitoring which can be physically integrated into the Carestation 600, receive electronic power from the Carestation 600, and communicate measured values to the Carestation 600 for display on the system display unit. When supplied as an option, integrated respiratory gas monitoring is provided via the GE CARESCAPE series (E-sCAiO and E-sCAiOV) respiratory airway modules (K123195) which is identical to the module used on Avance CS2, or the N-CAiO respiratory airway module which was cleared as part of the GE B40 monitor (K133576).

The Carestation 600 series Anesthesia Ventilator is used in the Carestation 600 series Anesthesia Systems. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. This version of the GE 7900 ventilator (cleared on K023366) is equipped with a built-in monitoring system for inspired oxygen (using an optional O2 cell or optional integrated gas module), patient airway pressure and exhaled volume. Flow sensors in the breathing circuit are used to monitor and control patient ventilation. This allows for the compensation of gas and tubing compression losses, fresh gas contribution, and small gas leakage from the breathing absorber, bellows and pneumatic system connections. User setting and microprocessor calculations control breathing patterns. The user interface keeps ventilation settings in memory. The user may change settings with a simple ventilation parameter setting sequence. A bellows contains breathing gasses to be delivered to the patient and provides a barrier keeping patient gas separate from the ventilatory drive gas. Positive End Expiratory Pressure (PEEP) is regulated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward from the patent breathing circuit.

This ventilator comes with a standard ventilation mode as well as optional ventilation modes.

Standard ventilation mode:
VCV (Time Cycled, Volume Controlled ventilation)

Optional ventilation modes:
PCV (Time Cycled, Pressure Controlled ventilation) VCV-SIMV (Synchronized Intermittent Mandatory Ventilation Volume Control) PCV-SIMV (Synchronized Intermittent Mandatory Ventilation Pressure Control) PSVPro (Pressure supported ventilation with apnea backup) PCV-VG (Pressure Controlled ventilation - Volume Guaranteed) PCV-VG-SIMV (Synchronized Intermittent Mandatory Ventilation, Pressure Controlled ventilation - Volume Guaranteed) CPAP+PSV (Continuous Positive Airway Pressure/Pressure Support)

The system can include an internal, factory installed, suction regulator and control visible from the front of the machine. It can mount different monitors using an arm or shelf mounts. The mounting is achieved through a combination of GE Healthcare adapters and other third party mounts, including one that allows for the physical integration of the GE Monitor Series B650 (K102239).

The provided text does not contain information about the acceptance criteria and study specifically for an AI/ML powered device. Instead, it describes a medical device, the Carestation 620/650/650c anesthesia system, and its premarket notification to the FDA. The document focuses on establishing substantial equivalence to a predicate device, the Avance CS2, through non-clinical testing.

Therefore, many of the requested details regarding AI/ML device evaluation criteria, such as sample sizes for test sets, data provenance, expert ground truth adjudication, MRMC studies, standalone performance, and training set information, are not available in this document.

However, I can extract the general acceptance criteria for the Carestation 620/650/650c device based on the non-clinical testing performed, which is focused on verifying its safety and functionality and establishing substantial equivalence to a predicate device.

Here's the information that can be extracted or deduced from the provided text:

1. A table of acceptance criteria and the reported device performance

The document broadly states that "Verification and validation testing was performed according to predetermined acceptance criteria." While specific numerical performance metrics are not provided, the types of tests conducted serve as the "acceptance criteria" categories for this device. The reported performance is that the device met these criteria.

2. Sample size used for the test set and the data provenance

Not applicable. The testing described is primarily non-clinical verification and validation testing of a hardware/software system, not a study involving a "test set" of patient data for an AI/ML algorithm. No specific sample sizes for these tests are mentioned beyond the implication that sufficient testing was done. The document does not refer to any patient data for testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This device is not an AI/ML algorithm that requires expert consensus for ground truth. Its functionality is tested against engineering specifications and regulatory standards.

4. Adjudication method for the test set

Not applicable, as there is no "test set" in the context of AI/ML evaluation. Product verification and validation involve testing against predefined specifications and requirements.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No. This document describes an anesthesia system, not an AI-assisted diagnostic device. Therefore, no MRMC study or evaluation of human reader improvement with AI is mentioned or relevant.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This refers to the performance of the Carestation 620/650/650c as a standalone medical device. The document explicitly states that "Extensive non-clinical testing was performed..." and that "The Carestation 620/650/650c has been thoroughly tested through verification of specifications and validation, including software validation." This means its standalone performance against design specifications was evaluated.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for this device's performance is its compliance with engineering specifications, functional requirements, and relevant voluntary and regulatory standards (e.g., AAMI / ANSI ES60601-1, IEC 60601-1-2). The testing aims to prove that the device operates as designed for its intended use.
