Description:

The GE Datex-Ohmeda Tec 7 family delivers agent-stable output across the full clinical flow span of 0.2 to 15 L min-¹. The Sevoflurane variant’s large-diameter dial offers 0.2 % graduations up to 1 %, then 0.5 % steps through 8 %, with an ergonomic push-release lock usable from either hand. A dry weight of 22 lb and 4.5-inch width slot neatly onto Selectatec-style manifolds without tools, and the factory-sealed calibration eliminates scheduled service. Internally, a metal-wick sump holds 75 mL reserve while a 300 mL charge fills the unit; 225 mL remains available for delivery after priming. Flow resistance stays below 15 cm H₂O at 5 L min-¹ O₂, and accuracy at 5 % dial is ±0.25 %. Operating range spans 64–95 °F with humidity to 75 % RH. Easy-Fil funnels simplify clean refills, while Quik-Fil cassettes further reduce exposure and downtime.

Economic Advantage:

Factory-service-free calibration and LED-lit fill points slash ownership costs: GE projects a five-year saving over legacy Tec 5 units by removing routine bench calibration and minimizing agent waste during refills. The 22-lb chassis lets hospitals redeploy vaporizers between ORs instead of buying spares, and the low resistance keeps fresh-gas flows low, trimming sevoflurane consumption up to 10 %.
