1.5 Safety facilities
ARGUS LCM/PLUS
1.5 Safety facilities
V Operating the device without the correctly rated fuse, or with defective cables,
constitutes a danger to life. Therefore:
– Do not operate the unit if the earth connection is suspect or if the mains lead is
damaged or suspected of being damaged.
– Damaged cable connections and connectors must be replaced immediately.
– The electrical safety devices, such as fuses, must not be altered.
– Ruptured fuses must only be replaced with the same type and rating as the orig-
inal.
1.6 Operation with other devices
V Use only accessories and other parts recommended or supplied by SCHILLER
AG. Use of other than recommended or supplied parts may result in injury, inaccurate information and/or damage to the unit.
V Ancillary equipment connected to the analogue and/or digital interfaces must be
certified according to the respective IEC standards (e.g. IEC/EN 60950 for data
processing equipment and IEC/EN 60601-1 for medical equipment). Furthermore all configurations shall comply with the valid version of the system standard IEC/EN 60601-1-1. Everybody who connects additional equipment to the
signal input part or signal output part configures a medical system, and is therefore responsible that the system complies with the requirements of the valid version of the system standard IEC/EN 60601-1-1. If in doubt, consult the technical
service department or your local representative.
– EC/EN 60601-1-1 states that the patient must remain at least 1.5 meters clear
of the unit. If this is not possible, a safety isolating transformer must be installed.
V Medical electrical equipment is subject in regard to the electromagnetic compat-
ibility (EMC) and its special precautionary measure. (see chapter 12.4 page 131)
V Portable and mobile Radio Frequency (RF) – communicating systems (such as
cell phones) can have influence to medical electrical equipment.

concentration is measured by detecting the absorption in this band. Due to the nature
of the measurement technique employed, user calibration is necessary with this system.
The basic components of the CO2 sensor (C-Cap bench) include
• IR source
• Dual element IR detector
• Optical filter
• Non-volatile memory
The IR sour ce emits energy that is directed towards a dual element thermopile IR de-
tector. The dual element design uses two opposing thermopiles connected in series.
A change in the ambient temperature is compensated by the two elements so the output won't be distorted. Only one element is exposed to energy from the IR source, resulting in a voltage change due to only that energy. The detector generates a voltage
based on the amount of energy it receives. The IR path between the IR source and
the detector contains an optical filter, which only allows a specific IR wavelength to
pass and the gas sample within the sensor chamber.
A temperature sensor is attached to the detector housing for temperature compensation beyond the thermopile's designed compensation, including temperature changes
in the system sensitivity.
The detector generates a voltage in the mV range and an OP-amp on the circuit board
amplifies the signal.

In the event that this condition occurs, the pneumatic system increases the pump speed to achieve a high clearing vacuum (HCV) for 5 seconds. If the occlusion is cleared by this action, the pump returns to normal operation.
If the occlusion is not cleared after 5 seconds, the module automatically reverts to a

However, if there are leaks within the overall system, the pump speed is increased to

depending on the magnitude of the leak. A specific connection may also be tested by

4.4.11 Respiration measuring (RRi)
Respiration Respiration is measured between the left leg- and the right leg patient electrodes
which are placed on the abdomen. The physical action of the patient breathing
causes impedance change and this is used to detect and calculate respiration ra te .
The resistance across the electrodes is approximately 1 kohm + 250 ohm and the
impedance change during respiration is between 0.1 and 3 ohm.
The input signals are modulated with 25 kHz, 5μA, which results in an amplitude
modulated signal. This signal is then high pass filtered, demodulated and wave
shaped and sent to the processor via the multiplexer.
Respiration measuring not possible when using HF-cable
.
Respiration Detection
As with the ECG signal, it is necessary to first determine where a respiration has taken
place (triggering). The respiration triggering in the ARGUS LCM is based on the following principle.
Art. no.: 2.540033 rev.: d
Picture: Determination of the Trigger Thresholds
Using a continuous time window of 32 seconds, the largest positive (max.) amplitude
and the largest negative (min.) amplitude is determined. The mean value is then calculated from these two functions. The upper and lower trigger threshold is determined
from this mean value.
Calculation of the Respiration Rate
The Respiration Rate is calculated as a continuous average according to the distances between the individual respirations. Only respirations which were triggered during
the respiration detection, are averaged.
The distances of 8 respirations are averaged. The respiration frequency is calculated
out of the average R-distance R

4.5 NIBP Processing
Overview Oscillometric technique The oscillometric technique does not use Korotkoff sounds to determine blood pres-
sure. The oscillometric technique monitors the changes in cuff pressure caused by
the flow of blood through artery. Even when the artery is occluded, the pumping of the
heart against the artery can cause small pressure pulses in the baseline pressure.
LCM NIBP processing The LCM reduces the cuff pressure at controlle d deflation rate . When the cuff pres-
sure goes down, blood starts to flow through the artery. Above the systolic pressure
the oscillation amplitudes are almost constant. The increasing blood flow causes to
increase the pressure pulse amplitude in the cuff.
This is known as SYS, Systolic Pressure (A). These pressure pulse amplitude continue to increase with decreasing cuff pressure until it reaches maximum amplitude (B).
The cuff pressure at which the greatest pulse amplitude is generated is known as
MAP, mean arterial pressure. At this point the oscillation amplitu des getting smaller
with decreasing cuff pressure. Before the amplitude stays constant small, it is the
point to read out DIA, Diastolic Pressure (C).
The manner in which the pulse amplitudes vary is often referred to as the pulse envelope. The envelope is an imaginary line that connects the peak of each pressure pulse
and forms an outline. The shape of the envelope is obser ved by the monitor using a
variety of techniques to determine the diastolic and systolic blood pressure.

Overall Accuracy Discussion Overall system accuracy shall be determined by considering various influences of the
pressure sensor accuracy, motion artifacts and other artifact created by pressure
valve, technical errors of electrical components, and the origin error of oscillometric
method.The origin error of oscillometric comes from the basic theory of that the MAP
is determined by the pulse. Therefore, there might be an error of the time between two
pulses. In another words, the greatest amplitude point of pulses co uld not represe nt

4.6 Temperature measuring
Function Principle The resistance is temperature sensitive and registers different temperatures with var-
ied Ohm values. The higher the temperature, the lower the Ohm value (NTC negative
temperature coefficient). This Ohm value is measured and processed by the Monitor.
Temperature Amplifier The temperature transducer contains a resistor with a known temperature coeffi-
cient (nominal value approximately 1300 ohms at 20°). The output from the temperature multiplexer is filtered and amplified and sent to the CPU via a second multiplexer and an opto coupler.
Temperature Calculation The temperature is calculated using the temperature resistance gradient and the re-
sistance values transmitted to the Monitor Unit:
Measurement accuracy of the System
Page 44
Reference resistances are known resistances which are independe nt of temperatures. The temperature resistance gradient is determined using the two reference resistances R1 and R2. A further reference resistance R3 is used to check the measurement accuracy at any given time.
The resistance values (ohm values) measured in the ARGUS LCM are entered on the
temperature resistance gradient. Therefore the temperature can be read from the
temperature gradient.
Using the reference resistances R1 and R2, the temperature resistance gradient is
determined and the upper and lower limits of the temperature measurement are simultaneously defined. Ohm values measured by the temperature sensor that are outside these upper and lower limits are invalid.
The reference resistance R* checks the accuracy of the temperature resistance gradient. If the deviation of its value to the temperature resistance gradients is too large,
no value is shown. The system has to be checked
Defective Sensors or errors in the system are recognized and shown as “<<“(below
15 °C) or “>>” (above 45 °C) in the measurement field and a technical Alarm appears.

4.8.1 Principles of Pulse Oximetry Technology
The principle of pulse oximetry is based on the red and infrared light absorption characteristics of oxygenated and deoxygenated haemoglobin. Oxygenated haemoglobin
absorbs more infrared light and allows more red light to pass through. Deoxygenated
(or reduced) haemoglobin absorbs more red light and allows more infrared light to
pass through. Red light is in the 600-750 nm wavelength light band. Infrared light is in
the 850-1000 nm wavelength light band.
Pulse oximetry uses a light emitter with red and infrared LEDs that shines through a
reasonably translucent site with good blood flow. Typical adult/paediatric sites are the
finger, toe, pinna (top) or lobe of the ear. Infant sites are the foot or palm of the hand

After the transmitted red (R) and infrared (IR) signals pass through the measuring site
and are received at the photo detector, the R/IR ratio is calculated. The R/IR is compared to a “look-up” table (made up of empirical formulas) that convert the ratio to an
value. Most manufacturers have their own look-up tab les based on calibration

0.5 equates to approximately 100% SpO
while a ratio of 2.0 equates to 0% SpO2.
At the measuring site there are constant light absorbers that are always present. This
are skin, tissue, venous blood, and the arterial blood. However, with each heart beat
the heart contracts and there is a surge of arterial blood, which momentarily increases
arterial blood volume across the measuring site. This results in more light absorption
during the surge. If light signals received at the photo detector are looked at ‘as a
waveform’, there should be peaks with each heartbeat and troughs between heartbeats. If the light absorption at the trough (which should include all the constant absorbers) is subtracted from the light absorption at the peak then, in theory, the resultants are the absorption characteristics due to added volume of blood only; which is
arterial. Since peaks occur with each heartbeat or pulse, the term “pulse oximetry”
was coined. This solved many problems inherent to oximetry measurements in the
past and is the method used today in conventional pulse oximetry.

Still, conventional pulse oximetry accuracy suffered greatly during motion and low

to hold up to 3.5 ml of moisture. So, depending on the application, the trap could last
a couple hours or as many as 8-24 hours. There is nothing in the trap that will show
how soon the trap must be replace. When the trap is full, the moisture eventually hits
