[Performance analysis of a new anesthetic system: the Temel Supra--part I].
OBJECTIVE
To evaluate the performance of a new anesthetic system that purports to provide novel advantages in ventilating the anesthetized patient.


METHODS
A performance analysis was carried out in our respirator function laboratory using lung simulators to assess the system, its degree of compliance with current regulations, and the degree of compliance with the manufacturer's claims.


RESULTS
The system is 100% effective. The internal compliance of the respirator was 0.13 +/- 0.01 mL/cm H2O, inspiratory resistance was 1.9 +/- 0.1 cm H2O/L/s, expiratory resistance was 3.1 +/- 0.3 cm H2O/L/s, and internal volume was 130 mL.


CONCLUSIONS
The Temel Supra device is versatile and meets the anesthetic requirements of patients undergoing any type of surgery. The possibility of using an open circuit, a low flow, a closed circuit, or a continuous flow without having to change to another system allows the anesthesiologist to make use of the advantages of each circuit without its drawbacks. The efficacy of the circuit is 100%. The low internal volume means that internal compliance is negligible and time constants are low, guaranteeing that the volume programmed is the same as the volume delivered and facilitating alveolar redistribution of gases. The monitoring and warning systems assure safe patient ventilation and accurate dosing of gases and anesthetic agents.
