.... The calibration curve is linear and passes through the origin with a bias of -0.9 V in most cases. The current output of 0.6 μA for 100% O2 at 37°C with a 6 μ Teflon membrane is equivalent to that of a single wire cathode of 100 μ diameter. The stability is 0.5% over a period of 10 h and 2% during several days...

... prosthesis (Zini-type), and group 4(n = 76): Teflon piston operation (Fisch-type). The mean air-bone gap was analyzed usingpure-tone audiometry (for 3 frequencies: 500, 1,000, and 2,000 Hz) before and 12 months aftersurgery. Results: The preoperative mean air-bone gaps (500, 1,000, and 2,000 Hz) were35.6 dB...
