Qualification - Weinmann VENTIlogic LS Instructions For Use Manual

• neurological, muscular and neuromuscular disorders, such as muscular
dystrophies, pareses of the diaphragm etc.
• central respiratory regulation disorders
• hypoventilation syndrome associated with obesity
2.2 Owner/operator and user qualification
As an owner/operator or user, you must be familiar with the operation of this medical
device. 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.
2.3 Description of function
2.3.1 Providing the therapy pressure
An electronically-controlled blower draws in ambient air through a filter and delivers it to
the device outlet port. From here, air flows through the patient circuit and the patient/
ventilator interface to the patient.
Sensors detect the pressure at the patient/ventilator interface and in the patient circuit, as
well as the respiratory phase change. The blower accordingly provides the respiratory
volume and the IPAP and EPAP / PEEP pressures prescribed by the doctor.
2.3.2 Display and operation
The display shows the therapy mode and, as a function of the mode, the currently applied
values for CPAP, IPAP and EPAP / PEEP, respiratory frequency (f) and volume. Spontaneous
or mechanical respiratory phase switches and the pressure change are also shown in
graphical form. Ventilation parameters can be set in standby mode and in ventilation
mode. The device is operated by a number of keys that give direct access to the most
important parameters, such as IPAP, EPAP / PEEP, frequency, inspiration time and volume.
A dial is used to navigate through the menu. Parameters are shown in an LC display.
A key code is used to prevent therapy values from being adjusted inadvertently. Operation
is locked when a padlock symbol is shown on the display. In the Physician menu, it is
possible to show ventilation curves such as flow curves and pressure/volume loops
(VENTIlogic LS only) in addition to therapy values.
