Collaborative study of the frequency of the fluoride-resistant cholinesterase variant in patients with malignant hyperpyrexia.

abstract：:This paper describes the use of solenoid valves for the production of binary gas mixtures. The system is controlled by a microprocessor and is capable of delivering accurate flows and concentrations of gases over the ranges commonly used in anaesthesia. Since the flow produced by the valves is pulsatile, a system for ...
