Safety-relevant information
028
WARNING
Risk of electric shock
If the SpO
2 sensor becomes damaged during
use, discontinue use, especially if there are
uncovered electrical contacts.
WARNING
Risk of patient injury
Incorrectly positioned sensors may result in
incorrect measurements which may lead to
patient injury.
Only use Nellcor sensors in the recommended
positions.
WARNING
Risk of patient injury
High intrathoracic pressure, Valsalva maneu-
vers, and other consecutive impairments of
the venous flow can lead to venous pulsation.
The pulse signal might fail.
Do not position the SpO
2 sensor where it
might be affected in this way.
WARNING
Risk of patient injury
If the SpO
2 sensor is used in the presence of
significant concentrations of dyshemoglob-
ins, such as carboxyhemoglobin or methemo-
globin, measurement accuracy may be re-
duced.
Do not rely on measurement data if the SpO
2
sensor is used under these conditions.
WARNING
Risk of patient injury
If the SpO
2 sensor is used in the presence of
intravascular dyes such as, e.g., methylene
blue, measurement accuracy may be inaccu-
rate.
Do not rely on measurement data if the SpO2
sensor is used under these conditions.
CAUTION
Risk of misleading data
Immersing the SpO
2 sensor in liquid may lead to
a malfunction and thus misleading data.
Do not immerse the SpO
2 sensor in liquid.
CAUTION
Risk of failure or inaccurate data
If positioned close to a bright light source, the
pulse signal may fail or the results may be inaccu-
rate.
The sensor must be protected from exposure to
bright light (e.g. surgical lamps and direct sun-
light).
