For your safety and that of your patients
Patient safety The design of the medical device, the accompanying documentation, and the labeling on the medical device are based on the assumption that the purchase and the use of the medical device are restricted to persons familiar with the most important inherent characteristics of the medical device. Instructions and WARNING and CAUTION statements are therefore largely limited to the specifics of the Dräger medical device. The instructions for use do not contain any information on the following points:
Information on electromagnetic compatibility General information on electromagnetic compatibility (EMC) according to international EMC standard IEC 60601-1-2: Medical electrical equipment is subject to special precautionary measures concerning electromagnetic compatibility (EMC) and must be installed and put into operation in accordance with the EMC information provided (see page 262).
–
Risks that are obvious to users
Portable and mobile radio frequency communication equipment can affect medical electrical equipment.
–
Consequences of obvious improper use of the medical device
WARNING Risk of electric shock
–
Potentially negative effects on patients with different underlying diseases
Do not connect connectors with an ESD warning symbol and do not touch their pins without implementing ESD protective measures. Such protective measures can include antistatic clothing and shoes, touching a potential equalization pin before and during connection of the pins, or using electrically insulating and antistatic gloves.
Medical device modification or misuse can be dangerous. CAUTION Risk of patient injury Do not make therapeutic decisions based solely on individual measured values and monitoring parameters.
All users concerned must be instructed in these ESD protective measures.
Patient monitoring The user of the medical device is responsible for choosing a suitable patient monitoring system that provides appropriate information on medical device performance and patient condition. Patient safety can be achieved by a wide variety of means ranging from electronic surveillance of medical device performance and patient condition to direct observation of clinical signs. The responsibility for selecting the best level of patient monitoring lies solely with the user of the medical device.

Storing the instructions for use
WARNING Risk of electric shock Connecting devices to the auxiliary outlets of the anesthesia machine can cause an increase in leakage current beyond permissible values if the protective conductor of a device fails. Check the leakage current when connecting devices to the auxiliary outlets. If connecting a device (or devices) increases the leakage current to a value which exceeds the permissible value, do not use the auxiliary outlets of the anesthesia machine: use a separate wall socket.
CAUTION Risk of incorrect use Instructions for use must be kept accessible to the user.
Training Training for users is available from the Dräger organization responsible, see www.draeger.com.
The system must fulfill the requirements for medical electrical equipment in accordance with the relevant standards, see "Technical Data", page 261.
Sterile accessories CAUTION Risk of medical device failure and of patient injury Do not use sterile-packaged accessories if the packaging has been opened, is damaged, or if there are other signs of non-sterility. Disposable articles must not be reprocessed and resterilized.

Product-specific safety information WARNING Risk of malfunctions
WARNING Risk of fire
Unapproved modifications to the medical device can cause malfunctions.
In order to prevent a fire hazard, explosive anesthetics, such as ether or cyclopropane, must not be used.
No modifications must be made to this medical device without the permission of Dräger. Dräger does not accept responsibility for modifications to the device made without the permission of Dräger. WARNING Risk due to barely audible alarms The user must remain within the hearing range of the acoustic alarm signal. This permits quick recognition and handling of the alarm. Adjust the volume of the alarm signal to the distance from the medical device. WARNING Risk due to a noisy environment When operating in a noisy environment, the volume of the alarm signals must be adjusted to suit. Always set the volume of the alarm signal sufficiently high. WARNING Risk of use error Various potentially dangerous situations may occur which demand the attention of trained personnel. The workstation may only be used under the permanent supervision of qualified medical personnel so that assistance can be provided immediately in the event of any malfunctions.

WARNING Risk of device failure and/or danger to patient Magnetic fields may negatively influence the proper function of the medical device, thus endangering the patient or user. The medical device must not be used in the vicinity of magnetic resonance imagers (MRI, NMR, NMI). WARNING Risk of explosion, fire If an oxygen leak is suspected within or near the anesthesia machine, do not initiate operation. Disconnect all oxygen supplies and contact a trained service technician. WARNING Risk of fire To prevent a fire hazard, drugs or other substances based on inflammable solvents, such as alcohol, must not be introduced into the medical device, particularly into the breathing circuit and the breathing system. Adequate ventilation must be ensured if highly inflammable substances are used for disinfection.

For your safety and that of your patients
CAUTION Risk of patient injury
CAUTION Risk of crushing
An incorrect diagnosis or misinterpretation of measured values, or other parameters, may endanger the patient.
Movable parts and attached parts can lead to crushing injuries. Pay special attention to edges, movable parts, and corners when working with the following parts:
Do not base therapy decisions on individual measured values or monitoring parameters only. WARNING Risk of patient injury If ventilation of the patient is no longer ensured due to an obvious fault in the equipment, the patient must immediately be ventilated with a manual resuscitator. Always keep an emergency manual breathing bag at hand. WARNING Risk of burns Conductive breathing hoses or face masks may cause burns during HF surgery.

Drawers Ventilator module Doors Writing table Swivel arms for mounted devices Accessories such as gas cylinders, vaporizers, CLIC absorbers, and CLIC adapters
CAUTION Risk of device failure Compressed gas supply (central supply or cylinder): To avoid damaging the device(s) attached to a gas supply, use only medical gases. Pay particular attention to national and international standards regulating the use of medical gases.
Do not use these types of hoses and masks in combination with HF surgery. CAUTION Risk of mechanical failure The shock and vibrations caused by transportation may lead to a mechanical failure. The application of a wall or ceiling mount is designated for buildings. Do not use the anesthesia machine for mobile facilities such as ambulances, helicopters or ships.

For your safety and that of your patients
Functional safety The essential performance consists in: –
Supplying the anesthesia workstation with O2 If the O2 supply (central supply or gas cylinder) fails, an alarm is issued.
–
Supply of the patient with adequately If the breathing gas contains insufficient levels of O2, an alarm is issued.
–
Patients are not supplied with excessively high anesthetic gas concentrations If excessively high anesthetic gas concentrations are delivered, an alarm is issued.
–
