Safety-related information
2.8.5
Standby mode Ventilation does not take place in standby mode. If connected, the patient may be put at risk. Ź Connect the patient only after the therapy has been started.
2.8.6
Keeping a manual ventilation device ready If a fault is detected in the medical device, its life-support functions may no longer be assured. The patient may be put at risk. Ź Keep an independent ventilation device (e.g., a manual resuscitator) ready. Ź Immediately start the ventilation of the patient using the independent ventilation device. If required, perform ventilation with PEEP and/or with an increased inspiratory O2 concentration.
2.8.7
Alarms Alarm volume If the alarm volume is too low, alarm signals may not be heard. The patient may be put at risk. Ź Set the alarm volume loud enough so that the alarm signals can be heard in the environment where the device is located. Ź The user must remain within hearing distance of the alarm signals.
2.8.8
Device Ventilation slots Obstructing or closing off the ventilation slots may cause the device to overheat. An alarm is issued if the device overheats. Ź Make sure air can easily enter the device at the ventilation slots. Sources of heat Direct sunlight or other external sources of heat may cause the device to overheat. Ź Keep away from sources of heat such as direct sunlight, radiant warmer, or spotlights. Penetrating liquid Penetrating liquid may cause the following: – Damage to the device – Electric shock – Device malfunctions As a result, the patient may be put at risk. Ź Ensure that no liquid penetrates the device. Ź Do not place any containers with liquids on or above the device.

2.8.12
Gases and solutions Combustible or explosive gas mixtures If oxygen concentrations over 25 Vol% or combustible or explosive gas mixtures occur, there is an increased risk of explosion and fire that may result in personal injury and property damage. Ź Do not operate the device in areas where oxygen concentrations exceeding 25 Vol% or combustible or explosive gas mixtures may occur. Ź Do not operate the device in areas where combustible solvents or explosive anesthetic agents are used. Ignition sources Ignition source (e.g., open flames or sparks) may lead to fires in the presence of oxygen. There may be a risk of personal injury. Ź Keep the device away from ignition sources. Increased oxygen concentration in the ambient air Medical device malfunctions may increase the O2 concentration in the ambient air. As a result, the medical device may ignite. Ź Do not use the medical device in rooms that are enriched with oxygen. Ź The medical device is suitable only for use in rooms with sufficient ventilation.
2.8.13
External flow source Unnoticed change in inspiratory O2 concentration If an additional flow is delivered by an external flow source, the actual O2 concentration delivered may deviate from the displayed values. The patient may be put at risk. Ź If necessary, use additional monitoring, e.g., external SpO2 monitoring. Negative impacts on the measured values An additional flow delivered by an external flow source may affect the measured values for airway pressure and flow. Ź Do not use additional flow.
2.8.14
Modifications to the product Modifications to the product may lead to malfunctions and unforeseen risks. This may result in injury to the patient or the user or in property damage. Ź Do not modify this product.

Safety-related information
Electromagnetic disturbances Wireless communication devices (e.g., cellular phones) and medical electrical equipment (e.g., defibrillators, electrosurgical devices) emit electromagnetic radiation. When such devices are operated too close to this device or its cables, the functional integrity of this device may be compromised by electromagnetic disturbances. As a result, the patient could be put at risk. Ź Maintain a distance of at least 0.3 m (1.0 ft) between this device and wireless communication devices, to ensure that the essential performance of this device is fulfilled. Ź Maintain an adequate distance between this device and other medical electrical equipment. In case of short electromagnetic disturbances as tested according to IEC 60601-1-2, the following performance degradations may occur: – Temporary black screens – Disturbances of CO2 measurement After elimination of the electromagnetic disturbances, the performance degradations end at the latest after 8 seconds. In case of present alarms, the secondary acoustic alarm system will be activated. The ventilation performance is not affected. The ventilation unit operation display will indicate pressure, volume, and FiO2. The ventilator was tested according to the recommendations of IEC TR 60601-4-2: Medical. During burst coupling of ±1 kV on mains, the following performance degradations may occur: – Temporary black screens – Disturbances of CO2 measurement After the burst coupling, the degradation of performance ends at the latest after 8 seconds without any user intervention. Changing to another power socket may help. Burst coupling in the power network can be minimized or prevented by using a corresponding mains filter in the power network.
2.8.20
Network security Impermissible usage of data interfaces may result in new risks. Ź Only create connections to data interfaces if permission for this has been obtained from the organization responsible (party responsible for IT and party in charge of the devices for the hospital). Ź Observe the following information: "Connections to IT networks", page 268.
