  • Page 23: Description Of Device

    The device can be used in both static or mobile operation, both at home and in appropriate hospital departments. Note VENTIlogic LS is not a ventilator for intensive care purposes in accordance with ISO 80601-2-12. The device can be used for weaning off invasive ventilation and converting to mask ventilation.

  • Page 24: Owner/Operator And User Qualification

    Observe the legal requirements for operation and use (in Germany, the regulations governing owner/operators of medical devices apply in particular). Basic recommendation: get a person authorized by Weinmann to provide you with proper instruction about the handling, use and operation of this medical device.
  • Page 25 In controlled modes T, PCV and VCV (VENTIlogic LS only) and in assisted-controlled modes ST, PSV, aVCV (VENTIlogic LS only) and aPCV, the doctor can set respiratory frequency in the range from 5 to 45 breaths per minute and inspiration time in the range from 15 % to 67 % of the respiratory period.
  • Page 26 In S, ST, PSV, aPCV, aVCV (VENTIlogic LS only), SIMV, MPVp and MPVv modes, the doctor can select one of 8 trigger stages for inspiration and one of 14 trigger stages for exhalation (not with aPCV, aVCV, MPVp and MPVv).
  • Page 27 The device has a remote alarm connection to support the monitoring of patient and device, especially when VENTIlogic LS is used for life-support ventilation. All high and medium- priority alarms, together with the No power supply alarm are passed to this connection.
  • Page 28 The remote alarm connection can be used to connect the device to the VENTIremote alarm remote alarm case. In hospital, the device can be connected directly to the hospital's own internal alarm system. 2.3.14 Recording therapy data Therapy data are stored in the device on a removable SD card. The VENTIviews PC software can be used to enable a doctor to evaluate the therapy data.

  • Page 29: Safety Instructions

    3. Safety instructions 3.1 Safety information Read these instructions for use carefully. They are a component of the device and must be available at all times. Use the device exclusively for the intended purpose described (see “2.1 Intended use” on page 23). For your own safety and the safety of your patients and in accordance with the requirements of Directive 93/42/EEC, please note the following.
  • Page 30 – It is essential to ensure that alarm VT is activated for life-support ventilation (VENTIlogic LS only). Only if these conditions are met can a blockage (stenosis) be detected. – Set the VT alarm appropriately.
  • Page 31 • Masks of third-party manufacture may only be used following authorization by the manufacturer, Weinmann. The success of therapy is put in jeopardy by the use of unauthorized masks or other types of patient/ventilator interface.
  • Page 32 • An exhalation system must always be used with leakage ventilation, otherwise the CO concentration in the breathing mask and tube would rise to critical values and thus obstruct breathing. • Ventilation modes MPVv and MPVp for mouthpiece ventilation may only be used on patients with a stable independent respiratory drive.
  • Page 33 Keep the replaceable battery away from fire or heat. – Only use and charge the replaceable battery with the system provided for it. – Only replace the replaceable battery with a genuine Weinmann replaceable battery. – Children may only use the replaceable battery under supervision.
  • Page 34 Note: • When planning your time, be aware that at low or very high outdoor temperatures, battery running time is considerably reduced. 3.1.4 Oxygen supply Warning! • If oxygen is being supplied to the respiratory flow, smoking and naked flames are forbidden.
  • Page 35 • Have servicing and maintenance work carried out only by the manufacturer, Weinmann, or by specialist staff expressly authorized by the manufacturer. • Have modifications to the device carried out only by the manufacturer, Weinmann, or by specialist staff expressly authorized by the manufacturer.

    The volume displayed may deviate from that actually delivered by up to 105 ml. – Use patient circuit WM 27181 from Weinmann to avoid this deviation in the display.

  • Page 39: Patient/Ventilator Interfaces

    Caution! Do not cover the device with blankets etc. The air inlet would be blocked and the device could overheat. This may lead to inadequate therapy and to damage to the device. 1. Connect the power cord to the power connector of the device.
  • Page 40 It is essential to follow the instructions for use of the patient/ventilator interface and of the patient circuit. 4.3.2 Double patient circuit (VENTIlogic LS only) In addition to the ventilation tube which delivers air to the patient, the pressure- measurement tube and the valve control tube, the double patient circuit also has an exhalation tube which routes exhaled air back to the device and into the ambient air.

  • Page 41: Connect Leakage Ventilation

    The pressure-measurement tube is the same length as the ventilation tube and leads to the Y-connecting piece where the ventilation tube and the exhalation tube are brought together. 4. Connect the valve control tube (5) to the connection of the device marked The valve control tube leads straight from the patient valve to the connection on the device and is therefore shorter than the pressure measuring tube.
  • Page 42 5. Note that maximum flow rate and the accuracy of dynamic pressure may deviate if you are not using Weinmann tubes. Information relating to a separate exhalation system Caution! Always use an exhalation system. Used air containing carbon dioxide escapes from the patient/ventilator interface (e.g.

  • Page 43: Connect Humidifier

    Follow the instructions for use for the exhalation system and for the patient/ventilator interface. Connect circuit for mouthpiece ventilation Proceed as outlined below to connect the leakage circuit for mouthpiece ventilation (WM 27651). Tube adapter 1. Plug the tube adapter supplied onto the ventilation outlet on the device.
  • Page 44 Note: The bacteria filter may not be operated on the device for more than 24 hours. Follow the instructions relating to period of use in “6. Hygiene treatment” on page 67. If the therapy device is intended for use by several patients (e.g. in a hospital), a bacteria filter must be used to prevent infections.

  • Page 45: Therapy With Oxygen Supply

    Combination with an oxygen sensor and a humidifier 1. Connect the oxygen sensor directly to the therapy device. 2. Connect the bacteria filter to the outlet of the oxygen sensor. 3. Connect the humidifier to the outlet of the bacteria filter. 4.
  • Page 46 4. Switch off the device. The safety valve for the oxygen supply automatically shuts off the oxygen supply after 1 minute. Oxygen can be supplied via an oxygen concentrator (e.g. Weinmann Oxymat 3), via the central gas supply system (only with corresponding pressure reducer) of a hospital, in the form of liquid oxygen with a continuous flow or of an oxygen cylinder with a corresponding pressure reducer.
  • Page 47 2. Plug the oxygen sensor (1) and air management adapter into the T-adapter (3). 3. Plug the T-adapter (3) onto the device outlet port (5). 4. Connect the sensor (1) to the oxygen measuring jack (4) with the aid of the cable. 5.

  • Page 48: Operation In The Event Of A Power Failure
