  • Page 6: Packaging

    PACKAGE CONTENT The Luft Mechanical Ventilation Analyzer package comes with the following items: 1 x Luft (PN 42000001) 1 x User Manual (PN 12000036) 1 x Calibration Certificate Accessories: 1 x Y-connector with hole (PN 11000064) 1 x Bacteriological filter (PN 11000074)

  • Page 7: Concepts

    CONCEITOS Mechanical Ventilation is a method adopted to support patients with respiratory failure, according to each clinical pathology present in this individual. There are some basic concepts present in this method, which need to be known by the technical professionals who will perform the calibration procedure, as follows: Calibration: a set of operations that establishes, under specified conditions, the relationship between the values indicated by an instrument...
  • Page 8 PCV: controlled pressure, ventilation performed with pressure control as the main parameter. The terminology may change depending on the manufacturer. Current Flow: airflow that passes through the flow sensor in the inspiratory and expiratory phases, according to the assembly adopted. Peak Flow: maximum flow value recorded at each cycle.
  • Page 9 Oxygen Cell: electrochemical cell responsible for reading the oxygen concentration. Note: The electrochemical oxygen cell must be compatible with a MAX-16 R114P70 type cell that has a voltage output of 9 to 16mV for a linear range of 0 to 100% oxygen concentration. M16x1...

  • Page 18 “Settings” Tab The settings tab presents the analyzer settings options, O2 cell calibration, connectivity, and language. It’s possible to adjust the trigger by selecting the settings tab andclicking on the Measurements option. This adjustment can be made in two ways: - Manual - Automatic To enable the automatic trigger mode, just uncheck the box next to Manual...
  • Page 19 Understanding the Trigger The trigger indicates the start and endpoints of each inspiration and expiration to the analyzer software. It is possible to integrate the flow curve to obtain the volume reading and other parameters from this point. Trigger adjustment can be made by flow and pressure, always observing the dynamics for each of them.
  • Page 20 Set Zero option. Moving Average Luft has an option to configure the use of a moving average. The system will perform some measurements according to the selected quantity and present the average of these values after the elapsed time.
  • Page 21 When clicking on the “O2 Sensor” option on the “Settings” tab, the following screen will be displayed: On this screen, the user can calibrate the O2 Cell. To do that, follow the instructions 21% calibration -Leave the flow inlet and outlet open to the environment, for about three minutes;...
  • Page 22 100% calibration Insert a continuous flow of O2 at the Luft flow inlet for about two minutes; After this time has elapsed, select the measure option located below the 100% oxygen option; Notes: A digital indicator of the cell reading can be observed at the top of the chart for both calibration procedures.
  • Page 23 Battery Charge Level The battery charge level indicator is shown between the Freeze Screen and Output Option. It is recommended to keep the minimum charge level at 10% to 15% of the battery. Otherwise, it will be necessary to perform a battery reset procedure (Read more in Defects and Solutions).

  • Page 24: Test

    Notes: ALWAYS turn off the device as indicated above. Turning off directly through the switch can cause DAMAGE to the software. TEST Iremos demonstrar nesta seção como será realizada a montagem do circuito juntamente com o analisador LUFT. A realização dos ensaios podem ser feitas na configuração unidirecional e bidirecional.

    1. Connect the tracheas of the inspiratory and expiratory branches through the Y-connector. 2. Connect the output of the Y connector to the Luft inlet port through an adapter or small trachea. 3. Connect a low-pressure line of the Y connector to the Low-Pressure inlet port.

  • Page 26: Unidiretcional

    1. Connect the trachea of the inspiratory branch to the fl ow inlet. 1. Connect the trachea of the inspiratory branch to the fl ow inlet. 2. Connect a small breathing tube or adapter at the Luft fl ow outlet and join on one side of the Y connector.

  • Page 27: O2 Cell Replacement

    Note: multiple connections in the assembly can make the flow more turbulent and consequently generate more noise in the flow reading. Always opt for a simpler assembly, also avoiding dead space with the use of smaller tracheas. O2 CELL REPLACEMENT The user can replace the O2 Cell if a change in the reading is identified.
