Desflurane consumption during automated closed-circuit

Background. The Zeus ® (Dräger, Lübeck, Germany), an automated closed-circuit anesthesia machine, uses high fresh gas flows (FGF) to wash-in the circuit and the lungs, and intermittently flushes the system to remove unwanted N 2.We hypothesized this could increase desflurane consumption to such an extent that agent consumption might become higher than with a conventional anesthesia machine

Fire detection systems

closed relay at the end of the power line, it is possible to monitor for a power failure to the detectors. The relay contacts are wired in series with the normally closed contacts of the detector relay base(s). Thus in the normal state the detection circuit is closed; in the case of fire or power failure the relevant relay contacts will open.

Difference Between Autotransformer & Conventional

A conventional transformer is a static device which transfers electrical energy from one circuit to another at the same frequency but different voltage. It works on the principle of electromagnetic induction, i.e., the electromotive force is induced in the closed circuit due to the variable magnetic field around it. The windings of the conventional transformer are electrically insulated, but

What are the differences between open circuits and
