For Your Safety and that of Your Patients
For Your Safety and that of Your Patients Strictly follow the Instructions for Use Any use of the apparatus requires full understanding and strict observation of these instructions. The apparatus is only to be used for purposes specified here. Maintenance The apparatus must be inspected and serviced regularly by trained service personnel at yearly intervals (and a record kept). Repair and general overhaul of the apparatus may only be carried out by trained service personnel. We recommend that a service contract be obtained with DrägerService and that all repairs also be carried out by them. Only authentic Dräger spare parts may be used for maintenance. Observe chapter "Maintenance Intervals". Accessories Do not use accessories other than those in the order list. Reusable accessories (e.g. after they have been prepared) have a limited life span. A number of factors during preparation and operation (e.g. disinfectant residues can damage the material during autoclaving) can increase the wear and decrease the life span considerably. Materials with external signs of wear such as cracks, deformation, discolouration, disbonding or similar must be replaced. Liability for proper function or damage The liability for the proper function of the apparatus is irrevocably transferred to the owner or operator to the extent that the apparatus is serviced or repaired by personnel not employed or authorized by DrägerService or if the apparatus is used in a manner not conforming to its intended use. Dräger cannot be held responsible for damage caused by noncompliance with the recommendations given above. The warranty and liability provisions of the terms of sale and delivery of Dräger are likewise not modified by the recommendations given above. Dräger Medical AG & Co. KGaA

Intended Use
Intended Use Dräger Vapor® 2000 is an unheated, calibrated anaesthetic vaporiser for the enrichment of dry, fresh medical gas in anaesthesia delivery systems with accurately-controlled concentrations of vapour from liquid anaesthetic agents. The concentration delivered is, for the most part, not influenced by operating and ambient conditions, such as temperature, gas flow and ventilation pressure. The Vapor 2000 is suitable for use in strong magnetic fields (MRI equipment) when used in accordance with the operating instructions on page 24. Each Vapor is calibrated for a specified anaesthetic agent and is only suitable for that anaesthetic agent. Different models of Vapor are specified for different anaesthetic agents and are marked accordingly. The Vapor is inserted in the fresh-gas line of the anaesthesia delivery system which typically delivers a continuous fresh-gas flow. The Vapor is connected between the fresh-gas flowcontrol unit and the fresh-gas outlet. The Vapor is not suitable for use with a breathing system due to high pneumatic resistance. Proper functioning of the Vapor is dependent on the direction of flow. It must be connected and operated in accordance with the direction of flow specified on the machine. The use of the Vapor with different anaesthesia delivery systems is, therefore, only permissible and safe when it is used with the appropriate special adapters. Simultaneous operation of several Vapors switched in series is not permissible, particularly for different anaesthetic agents. Dräger recommend that the output concentration is monitored to detect any hazardous output values, using a monitor which has continuous measurement and upper and lower alarm limits. Installation and/or operation with anaesthesia delivery systems in mobile vehicles, aeroplanes, helicopters and ships is only permissible after consultation with Dräger and their agreement. The Vapor must only be used by qualified medical personnel to ensure that any malfunction can be remedied without delay. According to US and Canadian law these machines must only be used by or on the instructions of a fully qualified medical practitioner.

At »T« setting Vapor may be moved in any position. If not at »T« setting, risk of incorrect output concentration, or of anaesthetic agent escaping otherwise.
Connecting and Interlock systems When the Vapor is used with different anaesthesia delivery systems, different connecting systems have to be used. When anaesthesia delivery systems have several Vapor connectors, the different Interlock systems1 ensure that only one Vapor can be used at any one time, while the others are switched off and blocked. The interlock system on the vaporiser and anaesthesia delivery system must be functional. Especially with Interlock 2, the nibs must be engaged and undamaged in both openings of the interlock disc. See also "Checking Readiness for Operation" Page 36. A malfunctioning Interlock may endanger the patient by causing overdosing or a mixture of anaesthetic agents. Plug-in adapter/plug-in connector to connect Vapor safely and change over quickly. Most plug-in connectors have valves to allow fresh gas to flow through, whether the Vapor is, or is not, connected. These plug-in connectors can be identified by the moveable valve inserts in the inner holes on the connector pins.

Preparation
Preparation Fitting connectors Use only authentic Dräger parts. Only selected materials may be used with anaesthetic agents in breathing gas. Connectors may only be fitted by trained service personnel, because they must be dismantled and checked. Risk of incorrect output concentration or escape of anaesthetic agent otherwise. ●
Remove protecting cap on gas inlet/gas outlet at the back – when fitted.
●
Always connect Vapor in such a way that the gas flow matches the illustration given and the arrow on the back.
If the flow is in the wrong direction an incorrect concentration may be delivered, often an increased concentration. Follow Instructions for Use for Anaesthesia Delivery System.
●
For conical connectors: the male cone on the connecting piece is the Vapor inlet; the female cone on the connecting piece is the Vapor outlet.

Check that the Vapor fits flush with the lower installation points and, when viewed from the side, is suspended from the machine in a vertical position.
Preparation
Filling Vapor Take care not to spill anaesthetic agent. Do not inhale anaesthetic agent vapour. Danger to health. Recommendation: ensure adequate ventilation when filling Vapor when not connected to anaesthesia delivery system. Only fill Vapor with the anaesthetic agent specified on it.1 Observe use-by date for anaesthetic agent. When using branded products from different manufacturers make sure that the correct agent is used, for instance, following the colour coding of the Vapor and the anaesthetic agent bottle: Halothane
red
Enflurane
orange
Isoflurane
purple
Sevoflurane
yellow
From a technical viewpoint the same anaesthetic agent from different manufacturers with different tradenames, which are identical in composition and physical and chemical properties and are approved as medicaments, can be administered separately or in combination in Vapor and monitored with Dräger anaesthetic agent monitors. Do not use a Vapor which has been filled or partly filled with the wrong anaesthetic agent or other substances. The concentration delivered may be significantly higher or lower than the concentration set on the control dial. Risk of explosion from combustible substances. Many anaesthetic-agent monitors do not identify mixtures of anaesthetic agents and/or detect that the anaesthetic agent being measured differs from the agent that was set. Unusual deviations in the concentration displayed on a monitor may indicate incorrect filling. If this has happened, mark Vapor for appropriate substance and call DrägerService for repair. Make sure that the drainage valve is closed as significant quantities of anaesthetic agent may escape if it is not. Keep Vapor upright, or hanging vertical, while it is being filled. If it is at an angle it can be overfilled which may lead to concentrations which are too high or too low.
1 Only use anaesthetic agents approved in the country of use.
