INTRODUCTION
SAFETY INFORMATION
LUFT Mechanical Ventilation Analyzer allows the verification of
Anesthesia Devices, Lung Ventilators, Oxygen Concentrators,
Flowmeters, Pressure Manometers of Medical Gas Networks, among
other applications. Luft measures bidirectional, unidirectional, high-
and low-pressure airflow, barometric pressure, oxygen concentration,
and ambient temperature and humidity.
It is integrated with the management system, enabling real-time integration
and reading of the values tested, registering them in the device’s repair
and maintenance records. Luft operates on a rechargeable lithium-ion
battery, capable of lasting three to five hours of uninterrupted testing.
For better conservation of your device and to prolong its useful life,
please consider the following:
1. Do not expose the device to high humidity.
2. Do not expose the device to temperatures above 50º C.
3. Respect the device’s battery life.
4. Insert the connectors only into the spots intended for operation.
5. Do not connect this device to the patient.
6. Replace the power cord if any damage is identified.
7. Replace accessories if any damage is identified.

8. Do not open the device without the expertise and the
manufacturer’s qualification.
9. Always examine the device before and after each use.
If you notice any irregularity with the device, do not put it into operation.
Depending on the problem, the device may suffer irreversible damage,
which will lead to costly maintenance or discontinuity. Whenever the
device fails, set it aside and contact the Arkmeds Support Team

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 specied
conditions, the relationship between the values indicated by an instrument
and the corresponding values of the quantities specied by standards.
Adjustment: operation performed in a corrective manner designed to make
a measuring instrument behave as recommended by the manufacturer. It
is performed in three ways: automatic, semi-automatic, and manual.
Gas condition corrections: The volume of a gas varies depending
on its temperature, pressure, and water vapor content, although the
absolute value of the number of gas molecules remains constant. Thus,
it is necessary to carry out the correction for each type of test situation,
conguring between:
VCV: controlled volume, ventilation performed with volume control as
the main parameter. The terminology may change depending on the
manufacturer.
• ATPD - Ambient Temperature and Pressure, Dry (0% humidity)
• ATPS - Ambient Temperature and Pressure, Saturated (100% humidity)
• STPD - Standard Temperature 0 °C, Standard Pressure 760 mmHg, dry
(0 % humidity)
• BTPS - Body Temperature 37 °C, Ambient Pressure, Saturated (100% humidity)

PCV: controlled pressure, ventilation performed with pressure control as the
main parameter. The terminology may change depending on the manufacturer.
Current Flow: airow that passes through the ow sensor in the inspiratory
and expiratory phases, according to the assembly adopted.
Peak Flow: maximum ow value recorded at each cycle.
Frequency: is the frequency of mandatory inspirations.
I:E Ratio: is the ratio between Inspiration and Expiration during ventilation.
Inspiratory Time: time elapsed within a cycle to perform the inspiratory phase.
Expiratory Time: time elapsed within a cycle to complete the expiratory phase.
Current Volume: volume delivered to each airow passage.
Tidal Volume: volume delivered during the inspiratory and expiratory phases.
Minute Volume: the relation between tidal volume and frequency, resulting in
the total volume delivered each minute.
Current Pressure: pressure delivered in real-time.
Peak Pressure: maximum pressure value reached.
Peep Pressure: Pressure value remaining at the end of each ventilation cycle.
High Pressure: pressure of the medical gas networks to supply the fans.
Oxygen Concentration: value of the oxygen concentration present in the
tested system.
Environmental conditions:
Temperature: Indicates the temperature of the test site.
Humidity: Indicates the relative humidity of the air at the test site.
Barometric Pressure: Indicates the barometric pressure reading at
the test site.
Altitude: Indicates the altitude reading of the test site in relation to
barometric pressure.
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.
