Background information and Identification

The GE Tec 7 is a medical anesthesia device produced by General Electric, although the device is also produced under its subsidiary Datex-Ohmeda . This device is only a part of the entire anesthesia system and was released in June of 2007. The device is responsible for controlling the pressure, flow, and volume of the anesthetic agents to the patients. This device delivers anesthesia through a gas to the lungs of the patient, rather than to the blood stream through an IV drip.

The GE Tec 7 features two options: Easy-Fil and Quick-Fil, although Quick-Fil is available when using Sevoflurane only. The dial on the device is calibrated for precise changes to the agent delivery.

The GE Datex-Ohmeda Tec 7 Anesthesia Vaporizer was recalled by the FDA for issues with process control. More information about this recall can be found on the FDA recall page.

The physical characteristics of the GE Tec 7 Isoflurane device include a weight (empty) of 15 lbs 6 oz (7 kg), a depth of 8.25 in (210 mm), a width of 4.375 in (110 mm), and a height (unlocked position) of 9.875 in (250 mm) (Avante Health Solutions, 2017). The agent capacity of the GE Tec 7 device is 225 mL of free volatile anesthetic agent while charged, and 300 mL (nominal) while charging. To charge dry vaporizers and the retention of 75 mL (nominal) the device is retained by wick system (Soma TECH INTL, 2018). The GE Tec 7 even comes with an innovative non-spill system. The vaporizer limits the movement of liquid agent if the vaporizer is tilted or inverted, protecting internal components and helping maintain output within clinically acceptable limits (GE Healthcare, 2018, p.4).

Technical Specifications

• Tec 7 Vaporizers are designed to provide consistent output throughout the clinical flow range from 200 mL/min to 15 L/min.

  • Models are available for Isoflurane, Sevoflurane and Halothane.

  • Tec 7 Vaporizers are equipped with a large diameter control dial, which incorporates fine graduations of 0.2% between 0 and 1%, and 0.5% from 1% to 8%. The dial for Sevoflurane is marked in steps of 0.2% up to 1% v/v, and in steps of 1% between 1% and 8%.

  • The easy-turning dials and small graduations on the Tec 7 Vaporizer help you fine tune anesthetic delivery over the range of dial settings and flow rates.

  • To help minimize filling frequency, the Tec 7 Vaporizer accommodates 225 mL of anesthetic agent.

  • The Tec 7 Vaporizer can be mounted on GE Healthcare anesthesia delivery systems equipped with the Selecta Tec* manifold without tools and without taking the anesthesia system out of service.

  • An innovative non-spill system in the Tec 7 Vaporizer limits movement of liquid agent if the vaporizer is tilted or inverted, helping to protect internal components

  • The dials of the Tec 7 Vaporizers for enflurane, isoflurane and halothane are calibrated to 5% v/v in steps of 0.2% up to 1%, and in steps of 0.5% from 1% to 5% at 21°C using O2 at 5 L/min as the carrier gas (MDI Medicare, 2017).

  • Each agent-specific Tec 7 incorporates significant performance, convenience, and ergonomic benefits with important features to help improve agent delivery and reliability while helping to reduce overall operating costs (MFI Solutions Page, 2017).

  • Vaporizer holds 225 mL of anesthetic agent to reduce filling frequency (Datex Ohmeda, 2018).
