Alarm test
1. Apply the SpO
2
sensor to the patient.
2. Set the lower SpO
2
alarm limit to 99%.
3. When the SpO
2
value is lower than the alarm limit, an alarm is issued.
4. Reset the alarm limit to its original value.
• The pulsoximeter enables the continuous non-invasive monitoring of the functional
oxygen saturation of the arterial hemoglobin and the pulse rate. When the signal
is received from the patient sensor, the Masimo SET signal extraction technology
is used to calculate the patient's functional oxygen saturation and pulse rate.
• The display shows the continuous progress of the numeric SpO2, pulse rate,
plethysmographic waveform and signal quality values.
• The displayed plethysmographic waveform is not proportional to the pulse volume.
• The update period of the measurement readings on the display is 0.2 seconds.
• According to the relevant standards, the temporary alarm suppression must be set
to maximally 2 minutes.
• Check low/high setting of the SpO2 sensor see chapter
page
Low
sensitivity
mode provides the best combination of sensitivity and sensor off
detection performation. this mode is recommended for the majority ofr patients.
High
sensitivity mode should be used for patients, where optaining a reading is
most difficult. This mode is only recommended during procedures and when clini-
can and patient contact is continuous.
V
Only use sensors recommended from SCHILLER for SpO2 measurement with
the Argus LCM. Other oxygen transducers (sensors) may lead to improper per-
formance.
V
The information in this manual does not overrule any instructions given in the
Masimo operating manual, which must be consulted for full instructions.
V
Do not use the pulsoximeter or Masimo sensors during magnetic resonance im-
age scanning. Induced current could potentially cause burns, and the pulsoxime-
try may affect the image and the accuracy of the measurements.
V
Before using the sensor, carefully read the sensor directions for use.
V
Tissue damage can be caused by incorrect application or use of a sensor. Inspect
the sensor site as described in the sensor directions for use to ensure skin integ-
rity and correct positioning and adhesion of the sensor.
V
Do not use damaged patient cables, damaged sensors or sensor with exposed
optical components.
V
Substances causing disturbances: Carboxyhemoglobin can lead to falsely high
measurement readings. The degree of the deviation approximately corresponds
to the quantity of carboxyhemoglobin. Colours or substances containing colours
that influence the natural blood pigments can also lead to incorrect measurement
readings.
V
Exposure to excessive illumination, such as surgical lamps (especially those with
xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps or
direct sunlight, can affect the performance of an SpO2 sensor. To prevent expo-
sure to excessive illumination, ensure that the sensor is correctly applied and that
it is covered with an opaque material, if required. If these measures are neglect-
ed, excessive illumination can lead to incorrect measurements.
V
Change the sensor's position at least every 4 hours.
