ANESTHESIA GAS MACHINE> NEW GAS MACHINES

New (and old) Gas Machines

Advanced ventilators are the biggest difference between new and older gas machines. (Review previous section on this site on ventilators now.)

This page is a general survey of gas machines available for purchase, or older machines still in use in North America. For each gas machine model you may find comments, important features, a picture, how it fits in with your current equipment, and limited specifications (like size, number of vaporizers or flowmeters).

The Paragon Platinum SC430 features traditional glass FGF flowmeters and conventional vaporizers, combined with an advanced ventilator. The breathing circuit is latex free. Absorbent capacity is 1.3 kg of loose or pre-packed absorbent. The standing bellows may be driven by oxygen or air.

The AV-S ventilator on the Paragon Platinum SC430 offers integrated FGF compensation, VPO (volume, pressure, oxygen) and spirometry monitoring, and automated compliance and leak testing. VCV (20-1600 mL/breath), PCV (to 70 cm H2O), and PSV modes are available with integrated electronic PEEP. Insp/Exp ratio is selectable from 1:0.3 to 1:8. Pmax 80 cm H2O.

Paragon also sells the Mindray A5. From the web site: "The A5's user interface and ergonomic design simplifies workflow. The 15" touch screen enables clinicians to easily select ventilation settings, so less time is spent maneuvering and more time is devoted to patient care. The A5 provides a range of advanced ventilation modes enabling effective care across the range of patient acuity types. Integrated spirometry offers additional information and enhances careful decision making. The auxiliary Oxygen/Air flow meters deliver blended gas through the nasal cannula, allowing the clinician to maintain their preferred clinical practice without increased risk of surgical fire."
