2. Description of unit

2.1 Intended use

The VENTImotion is a home ventilation unit for non-invasive, non-life support ventilation of adult patients with respiratory insufficiency in whom there is evidence of autonomous respiratory drive. This corresponds to the following clinical pictures:

•restrictive and obstructive ventilation disorders like paresis of the diaphragm, OSAS, COPD

•disorders of the respiratory mechanism like scoliosis, deformity of the thorax

•neurological, muscular and neuromuscular disorders

•central respiratory regulation disorders

The VENTImotion is not suitable for life-support use.

Use the unit only for the purpose described here.

2.2 User qualification

The VENTImotion may only be used by a doctor on an individual basis for a specific patient.

When the VENTImotion is handed over to the patient, the doctor in charge or hospital staff must instruct the patient in how the unit works.

2.3 Functional description

Provision of therapy pressure

An electronically-controlled fan draws in ambient air through a filter and delivers it to the unit outlet. From here, the air flows through the hose system and the mask to the patient.

Sensors detect the pressure in the mask and in the hose system and also the respiratory phase switch (trigger point). The fan accordingly provides the IPAP and EPAP pressures set by the doctor.

8	Description of unit

Therapy modes

The VENTImotion can be operated in six therapy modes: CPAP, S, ST, T, SX and SXX mode. Your doctor will set the mode required for your therapy on the unit.

Your doctor can activate volume compensation. Minimum volume and maximum pressure increase are set for this purpose. If the minimum volume is undershot, the unit automatically increases pressure continuously until the set maximum pressure (therapy pressure + max. pressure increase) is reached.

In time-controlled mode T and in assisted-controlled mode ST, your doctor can set respiratory frequency in the range from 6 to 45 breaths a minute and inspiration time in the range from 20 % to 67 % of the respiratory period.

In assisted modes S, SX and SXX and in assisted-controlled mode ST, your doctor can select one of 6 trigger stages for both inspiration and expiration. Your doctor can switch off the trigger for expiration. Expiration is then time-controlled.

If no breath is taken into the unit in S mode, the pressure is switched at a minimum frequency of 6 breaths a minute.

Other functions

The soft start function makes it easier to fall asleep. Your doctor sets initial pressures for inspiration and expiration which rise continuously to the therapy pressures during the soft start phase. This function can be locked out by the doctor.

The VENTImotion has an auto switch-on system. If this is activated, the unit can be switched on by a breath being taken into the mask. The unit is still switched off using the on / off switch .

The display shows therapy mode and, depending on mode, the values currently being applied for CPAP/IPAP and EPAP and for respiratory frequency (f). Spontaneous or mechanical respiratory phase switches are also displayed and the pressure change shown in the form of a graph.

4.2 Put on the Mask

The VENTImotion is designed for use with nasal, nasal/oral and full facial masks. Proceed as follows to put on the mask.

1.Adjust the forehead support of the l mask (if provided).

2.Connect the headgear/the headband to the mask and position the mask.

3.Adjust the headgear/headband so that the bulge of the mask only results in low pressure to prevent pressure points on the face.

Please refer to the operating instructions for the relevant mask.

4.3 Accessories

Separate exhalation system

A separate exhalation system is required if you are using a mask without an integrated exhalation system.

Used carbon dioxide (CO2)-enriched air escapes from the mask through the exhalation system. Without an exhalation system, the CO2 concentration would rise to critical values in the mask and hose, thus hindering your breathing.

The exhalation system also allows you to breathe through the nose or mouth if the unit malfunctions. In the event of a malfunction with a full facial mask, you breathe through a safety valve on the mask.

Exhalation sy- stem

Sleeve

The sleeve on the end of the hose system has a diameter of 19.5 mm and fits over a 22 mm standard cone. Put the exhalation system on the sleeve of the creased hose.

Hose system

Please refer to the operating instructions for your exhalation system.

16	Set up unit

Humidifier VENTIclick

The VENTIclick humidifier is positioned between the VENTImotion and the hose system. The inlet connection stub and the electrical connection of the heating element must be pointing at the VENTImotion. Please also see the operating instructions for the VENTIclick.

Oxygen supply using the VENTI-O2

The supply of oxygen must have been prescribed by the doctor in charge.

For safety reasons (risk of fire), the direct introduction of oxygen into the hose system or the mask is not permitted without a special protective device.

On the VENTImotion, the introduction of oxygen is permitted solely using the VENTI- O2 oxygen valve, WM 24200. This valve allows up to 4 l/min. of oxygen to be introduced. In the event of a fault, the VENTI-O2 gives off the oxygen into the ambient air. This means that it cannot accumulate in the unit.

The oxygen can be supplied using an oxygen concentrator (e.g. Oxymat 3), central gas supply system, liquid oxygen or an oxygen cylinder with a suitable pressure reducer. The external oxygen source must be equipped with a flow-adjustment device independent of the VENTI-O2.

You must follow the safety instructions for handling oxygen without fail, as well as the operating instructions for the VENTI-O2 oxygen valve and the oxygen device used.

Set up unit

17

Bacteria filter

If the VENTImotion is intended for use by several patients (e.g. in hospital), bacteria filter WM 24148 should be used to protect against infection. It is installed between the hose system and the VENTImotion or the VENTIclick. Please also observe the enclosed operating instructions for the bacteria filter.

Caution!

The bacteria filter represents an additional resistance in the air stream. This may lead to a change in the response characteristics of the trigger. For this reason, you should have the unit parameters reset if a bacteria filter is fitted retrospectively.

VENTIpower

For mains-power independant operation VENTIpower is available.

VENTIpower can also be connected to VENTImotion in parallel to mains power. VENTIpower then remains in standby mode. If mains power fails, VENTIpower automatically supplies power to the therapy device with a delay of about 4 seconds.

Using VENTIpower you can operate VENTImotion independant from mains power in the carrying bag WM 24888. To do so place VENTIpower in the dedicated section of the carrying bag and connect it to the therapy device.

Please also observe the operating instructions for VEN-

TIpower.

6.2 Cleaning

Clean hose system

1.Detach the hose system from the unit and the exhalation system.

2.Remove one end of the pressure measuring hose

(shake gently if necessary) and seal it with the sealing plug provided. At the other end, use the second sealing plug to seal the small opening of the adapter to prevent water getting inside.

3.Clean the creased hose so no residues remain using a small amount of detergent in warm water. Rinse the inside of the hose thoroughly in the process.

4.Rinse both the inside and the outside of the creased hose thoroughly using clean warm water.

5.Shake the hose system thoroughly.

6.Hang up the hose system and allow to drip to prevent moisture getting into the VENTImotion.

7.Remove the plugs from the pressure measuring hose.

Dry the hose system using the VENTImotion

1. If water accidentally gets into the pressure measuring hose, insert the red drying adapter supplied in the unit outlet.

2. Insert the adapter of the hose system in the unit outlet or if necessary, onto the red drying adapter.

3.To activate the drying process, press the on / off

switch . Use the menu switch to reach the patient menu. Press the dial to start the drying process. The unit now dries the hose system.

6.3 Disinfection, sterilization

If necessary, for example after an infectious illness or if the unit has become unusually soiled, you can also disinfect the housing, the connecting cord, the hose system, the bacteria filter housing, the VENTIclick, the VENTI-O2 and the VENTIpower. Refer to the operating instructions for the disinfectant used. We recommend that you wear suitable gloves (e.g. household or disposable gloves) when disinfecting the equipment.

Unit

The housing and the connecting cord of the VENTImotion are cleaned by simply being wiped over with disinfectant. We recommend TERRALIN for this purpose.

Hose system

We recommend GIGASEPT FF as disinfectant. When using GIGASEPT FF, use the same procedure as described under "Cleaning".

After disinfecting, rinse all parts thoroughly in distilled water. Let the parts dry completely.

Let the hose system drip. Dry the hose system using the VENTImotion as described in 6.2.

•Creased hose WM 24130 (clear) can be cleaned using hot water up to 70 ˚C. Sterilization is not permitted.

6.4 Change in patients

If the unit is being operated with a bacteria filter, please note the following:

•change the bacteria filter

or

•sterilize the bacteria filter and change the particle filter located inside it.

If the unit is to be utilized for another patient without using a bacteria filter, it must undergo hygienic preparation beforehand. This has to be carried out by the manufacturer (Weinmann) or a dealer.

The procedure used for hygienic preparation is described in the inspection sheet and in the service and repair instructions for the VENTImotion.
