Löwenstein Medical Ventilogic LS Ventilator Analysis Report

Overview and Device Identification

The device shown in the images is a Ventilogic LS model ventilator from the Löwenstein Medical brand. This identification is based on the brand and model name clearly visible on the device’s screen during startup and operation. The device is a portable mechanical ventilator designed to provide both invasive and non-invasive respiratory support. The overall design of the product, the quality of the logo and screen software, indicate an original device.

Areas of Use and Function

The Ventilogic LS is used for patients with chronic respiratory failure or those who require long-term respiratory support. Thanks to its flexible design, it is suitable for use in hospital intensive care units, home care services, and mobile health services such as ambulances. The device has the capability to operate with different patient circuits (leakage circuit, single-patient circuit with valve, and dual-patient circuit with valve). The screen data in the image indicates that the device is operating in pressure-controlled modes.

Physical Condition and Deformation

There is a single ventilator device in the images. The overall condition of the device appears used but well-maintained. No significant color fading or serious deformation is observed on its white casing. There are slight signs of use and possible dust accumulation on the surface of the casing, especially in the lower-left air outlet area. However, in general terms, there are no noticeable large scratches, cracks, or dents on the device’s casing. The device’s carrying handle, buttons, and rotary control knob appear mechanically sound.

Electronic Components and Screen Analysis

The electronic components of the device are in working condition. In both images, the screen’s backlight is active and the display is clear.

• Startup Screen: The first image shows the device’s startup screen. On this screen, the “LÖWENSTEIN medical” logo and the “VENTIlogic LS” model name below it are clearly legible.
• Operating Screen: The second image shows the device’s active operating screen. The following ventilation parameters and data are monitored on this screen:
  • PS (Pressure Support): 20.0 hPa
  • PEEP (Positive End-Expiratory Pressure): 5.0 hPa
  • f (Frequency/Respiratory Rate): 11.0 /min
  • Ti (Inspiratory Time): No information (the “s” unit is present in the relevant field, but the value is not legible)
  • VTi (Inspiratory Tidal Volume): 0 ml (This zero value suggests that a patient circuit is not connected to the device or that the measurement has not yet started.)
• At the top of the screen, there are expressions that may be Turkish, such as “pasifist” and “çok kritik” (very critical). These expressions may indicate an alarm condition or a mode the device is set to.

Accessories and Connection Ports

Apart from the device itself, no accessories (patient circuit, power cord, oxygen hose, carrying case, etc.) are present in the images. On the lower-left side of the device, the air outlet port where the patient circuit is connected is visible. No cracks or damage are observed on this port. No other connection ports or label details (serial number, REF code, year of manufacture) can be discerned in the image.

Potential Malfunction Risk

There are no obvious malfunctions related to the device in the images (e.g., cracks, non-working screen). The fact that the device’s screen is on and displaying data indicates that its basic electronic functions are active. However, the “çok kritik” (very critical) warning on the operating screen and the VTi value of “0 ml,” while possibly a normal condition when no patient circuit is connected, could also indicate a need for sensor or calibration adjustments. As the overall physical condition of the device is good, no serious potential risk of malfunction is observed.
