2.3 Measuring conditions
General
• Follow the instructions for use for the pulsoximetry sensor and the diagnostic nasal
cannula.
• Follow the instructions for attaching the sensors and components.
• Correct measurements are possible only if the system is operated properly.
• Contamination of the sensors, as a result of secretions or moisture, for example, can
falsify measurement results.
• The accuracy of analysis results may be restricted and measured values may be falsified
under oxygen therapy, especially if no diagnostic nasal cannula is used.
Measure using the diagnostic nasal cannula
• Use only the genuine diagnostic nasal cannula.
• Do not use a damaged diagnostic nasal cannula.
• The diagnostic nasal cannula is a disposable item and may not be reused.
• The tube of the diagnostic nasal cannula may not be pinched during the measurement.
• If the diagnostic nasal cannula is incorrectly attached, measurement results may be
impaired.
• Significant movements of the tube may falsify measurement results.
• Large quantities of secretion (colds) or blood (nosebleeds) may impair the measurement
of respiratory flow and snoring. Carefully wipe off all contamination, e.g. secretions
after sneezing.
Measure using the pulsoximetry sensor
• Always secure the connecting cable of the pulsoximetry sensor to the patient’s finger
or hand using a plaster so that it is not irritating and the pulsoximetry sensor cannot
slip out of position.
• Wearing the pulsoximetry sensor for too long causes pressure points. Switch the
pulsoximetry sensor to a different finger at regular intervals.
• Ensure that the LEDs and the receiver in the pulsoximetry sensor are not dirty or moist.
• Varnished or artificial fingernails falsify the measurement results of the pulsoximetry
sensor.
