How anaesthesia vaporisers work explained simply. Inhalational anaesthetic agents need to be delivered to the lungs for them to work. Of course one cannot simply pour them into the lungs! A much more acceptable way is to convert the liquid inhalational agent into a form that can be delivered by the inhalational route to the patient. A device which converts liquid to vapour is called a vaporiser.

Available in a wide range of fittings and agents, the Pisces vaporizer offers maximum reliability with the minimum of fuss. The Pisces vaporizer has been uniquely designed to be easily maintained. Each agent specific vaporizer signifies performance, convenience and ergonomic benefits with improved safety features to help improve agent delivery.
Clinical Performance: Due to design improvements in the gas pathways, the Pisces vaporizer excels in output stability over a wide range of variables and can work in the most extreme conditions.
Gives superb performance over a wide range of vapor concentration, temperature, particularly at low flows. Accuracy and Stability: All Pisces vaporizers are calibrated on a laser refractometer and are fully flow and temperature compensated to ensure output stability. Pisces vaporizers are precision engineered in the manufacture, fully tested and quality assured to comply with the most stringent of standards.
Ergonomically Designed: The Pisces vaporizer has been designed to be simple to use. Safety: All Pisces vaporizers are color coded, have clear agent-level indicators and a tamper proof label for complete security.
Durability: Constructed from specially selected materials, the Pisces vaporizer is resistant to wear from anesthetic agents and the lack of moving parts within the vaporizer itself ensures that the product is extremely robust.
Modern Anaesthesia Vapourisers
E-mail: ni. This article has been cited by other articles in PMC. Abstract Inhalational anaesthetic agents are usually liquids at room temperature and barometric pressure and need to be converted to vapour before being used and this conversion is effected using a vapouriser. Vapourisers have evolved from very basic devices to more complicated ones. Anaesthetists should understand the basic principles of anaesthetic vapouriser, including the principles that affect vapouriser output and how they influence vapouriser design.
Modern vaporizers[ edit ] There are generally two types of vaporizers: plenum and drawover. Both have distinct advantages and disadvantages. The dual-circuit gas-vapor blender is a third type of vaporizer used exclusively for the agent desflurane. Plenum vaporizers[ edit ] The plenum vaporizer is driven by positive pressure from the anesthetic machine , and is usually mounted on the machine. The performance of the vaporizer does not change regardless of whether the patient is breathing spontaneously or is mechanically ventilated.
