Elisee 350 User Manual July 2007

SAFETY REQUIREMENTS The Elisée™ 350 is applicable for adult and paediatric patients. This device is approved for critical care and continuous ventilation support. This equipment must be used on normal operating position properly settled on its feet, on its specific hospital trolley EasyView, on its specific little trolley or on its specific polyvalent support. During transport, ensure that the Elisée 350 is properly fixed to its support. Do not operate the ventilator in the presence of flammable anaesthetics or in an atmosphere of explosive gases : it might result in fire or explosion. The user should take the necessary precautions to ensure the specified electromagnetic compatibility (EMC) limits are not exceeded. In particular, where the device is used in the presence of short waves or high frequency generators, such as defibrillators, diathermy, electrosurgery or radiology devices, cellphones, etc., interference may occur if the energy emitted is higher than the levels stipulated in Directive 93/42 EC. This device may be affected by interference from electromagnetic fields exceeding 10 V/m. The ventilator is not protected against water splash (IPX0). During transport we recommend to use the device in its bag in order to offer a maximum protection against accidental splash. Keep the device away from direct sunlight. Do not expose the device to violent impacts. Do not start the ventilator up immediately after storage or transport in conditions other than the recommended operating conditions. Do not cover the ventilator and place it so that its cooling system is not obstructed. Do not obstruct the openings of the ventilator. This equipment doesn't deliver a pressure lower than the atmospheric pressure during the exhalation phase. The ventilator has been designed to avoid the inhalation of CO2 when the device stops: the rotary valve is closed so the exhaled gas runs through the exhalation valve instead of the inspiratory limb. The design of the ventilator and the properties of the turbine ensure that the maximum pressure supplied by the equipment cannot exceed 100 hPa (= 101.6 cmH2O). We recommend disconnecting all oxygen inputs when the device is on standby mode or when it is turned off. In case of turbine failure, the device can't be used even if a high pressure oxygen supply is connected. The electrical installation must comply with the local regulation standard. The device must be connected to the mains supply with the specific mains supply pack and the specific cable provided with the device. Any other connection may result in patient injury. If any doubts of electrical disruption on mains supply, the device must be used on the internal battery. To avoid personal injury and the risk of electric shock, as well as damages to the ventilator, do not operate the ventilator with its covers or panels removed. For any servicing, refer to technicians who have been trained to the ventilator maintenance. Before using the ventilator, check that all alarms are properly adjusted according to the ventilation parameters. Check all audible and visual alarms regularly, especially before connecting the ventilator to a new patient and in continuous ventilation support. Before connecting the ventilator to a patient, check all accessories to detect leakage risks and faulty elements. Do not connect antistatic and conductive patient circuits to the ventilator. Users must ensure the total resistance of patient circuit does not exceed 6 hPa (= 6.096 cmH2O) for a 60 l/min flow (adult configuration) or 6 hPa (= 6.096 cmH2O) for a 30 l/min flow (paediatric configuration).

INSTALLATION

II.1 Supply II.1.1 Power supply The ventilator can work from 4 different power supplies. The device automatically selects the power supply according to the following priorities: 1: Mains alternating voltage: 100-230VAC / 50-60Hz / 0.6-1 amp (connection to the mains supply pack). 2: DC voltage coming from an external power supply: 12-28VDC / 15 amps maxi: connection to the ventilator. 3: External battery. 4: Internal battery. In case of power cuts or if the mains supply cord is disconnected, an audible and visual alarm is released. It can be stopped by pressing the silence alarm button

.

Mains supply pack

This pack enables the connection between the device and the mains supply.

Assembly

Press firmly on the pack until the clip is locked

Press on the locking clip.

Installation

11

Connection

Connect the mains wire to the power port on the right side of the pack.

Fold down the retaining clip to avoid incidental disconnection of the cord.

L : The power supply is operative as soon as the device is connected to the mains supply. ! : When the ventilator is connected to the mains supply, turning the device off is impossible. The ventilator switches to standby mode to recharge the internal battery (and the external battery if it is connected to the ventilator). To switch the ventilator off, disconnect the mains supply.

This pack can be used outside its location. It is then connected to the device through an external supply cord (ref.S/E011930). This assembly enables the device to work on the mains supply and to recharge the external battery.

!

: When supplied with the external supply cord, the Elisée 350 manages this supply as an external supply, not as mains supply.

An external DC power (such as helicopter or car batteries from 12 to 28V – 15A max.) can be connected by connecting the external power cord to the power port on the right side of the ventilator.

! : When the ventilator is connected to an external power supply, turning the device off is impossible. The ventilator automatically switches to standby mode to recharge the internal battery (and the external battery if it is connected to the ventilator). To switch the ventilator off, disconnect the external power supply.

! : The external power supply ensures a charge of 1 hour and more.

12

Installation

External battery pack

Refer to the assembling and disassembling instructions of the mains supply pack (see above) to assemble and disassemble the external battery pack. This kind of power supply takes priority on the internal battery supply.

! : The external battery pack should be disconnected when the device is switched off.

The external battery is recharged through the device when connected to the mains supply or to an external DC supply.

L : When battery charge drops below 5%, Elisée 350 switches to the internal battery.

Mains supply pack

External battery pack

Internal battery This battery stands inside the ventilator. When the battery is disconnected of either the mains supply or the external DC supply or the external battery, the device uses the internal battery. While the ventilator is plugged in (mains supply or external DC supply > 19 +/- 1V), the internal battery is being charged automatically.

L: When the charge level falls below 15%, the Low battery alarm is triggered. Within a minimum of 5 minutes, this alarm is followed by the Flat battery alarm (charge less than 5%) signalling that ventilation will stop. Once ventilation has stopped, the device will shut down completely within a minimum time period of 5 minutes. During this time, connecting the device to an external power source (other than the external battery) will immediately restart ventilation.

Installation

II.1.2 Gas supply Ambient air enters the pneumatic circuit through an anti-dust filter.

! : Do not obstruct. Input of ambient air

The Elisée 350 is equipped with an input of low pressure oxygen (up to 400kPa). Oxygen can be delivered through: − An oxygen bottle equipped with a rotameter and a pressure reducer − An O2 concentrator − An O2 wall-supply equipped with a rotameter.

O2 is adjusted through a pressure reducer and a rotameter. Users can observe the evolution of this setting by watching FiO2 value in the measures display screen. Once the setting is completed, enter this value as the FiO2 parameter.

! : Connect O inlet only after the ventilation has started and disconnect it before you stop the ventilation (including 2

switch to Pause).

L : In the "extended features" display screen (cf. §IV.5.2), configure "Low pressure oxygen input: YES". High pressure oxygen High pressure socket tolerates pressure oxygen from 240kPa to 700kPa. Oxygen is delivered through: − An O2 wall-supply − An O2 bottle equipped with a pressure reducer.

L : It is advisable to set the concentrator at 400kPa +/-50kPa.

In high pressure, the Elisée 350 automatically manages FiO2 value according to FiO2 parameter.

L : In the "parameters options" screen, set" Low pressure oxygen input” at “NO". ! : Flexible hoses must comply with EN 739 standard specifications.

Installation

II.2 Assembly of patient circuits and accessories Elisée 350 allows users to connect a single or a double patient circuit thanks to its interchangeable exhalation valve control. Elisée 350 also provides a 1 bar oxygen input (default value) allowing the connection of a nebulizer in order to administrate aerosols. To complete this ventilation system, users can use a humidification system. Elisée 350 is a ventilator for adults and children ventilation. It is not designed for neonatal ventilation and should not be used with circuits having 10 mm in diameter. The user may use the following types of circuits: −

15 mm in diameter for ventilation with a tidal volume between 50 and 300 ml;

−

22 mm in diameter for ventilation with a tidal volume > 300 ml.

!

: Elisée 350 automatically detects the characteristics of the patient circuit during the manual test. A manual test should then be done after any change of circuit.

II.2.1 Connection of "single patient circuit" or "double patient circuit" support There are two supports:

−

"Single circuit" support allows connecting the exhalation valve control connector and the proximal pressure line.
