Measuring oxygen saturation (SpO
2
)
WARNING!
Patient hazard, incorrect measurement
►
The device has
no
alarm function. Never leave the patient
unobserved during a measurement.
►
The pulse oximeter is not an apnea monitoring device.
►
The pulse oximeter must not be used to analyze arrhythmia.
►
Incorrectly-applied sensors may lead to injuries at the point of appli
-
cation. Follow the Instructions for Use from the sensor manufactur
-
er.
►
Apply the blood pressure cuff and SpO
2
sensor to different
extremities to avoid falsifying measuring results.
►
Apply the intravenous pressure catheter and SpO
2
sensor to
different extremities to avoid falsifying measuring results.
►
Red and infrared light at fixed wavelengths is used for SpO
2
mea
-
surement. These wavelengths can affect other optical applications.
Information about the wavelengths used can be found in the Instruc
-
tions for Use for the sensor used.
►
As with all medical equipment, carefully route patient cabling to
reduce the possibility of patient entanglement or strangulation.
►
Do not place the pulse oximeter or accessories in any position that
might cause it to fall on the patient.
►
Do not start or operate the pulse oximeter unless the setup was
verified to be correct.
►
Do not use the pulse oximeter during magnetic resonance imaging
(MRI) or in an MRI environment.
►
Do not use the pulse oximeter if it appears or is suspected to be
damaged.
►
Explosion hazard: Do not use the pulse oximeter in the presence of
flammable anesthetics or other flammable substance in combina
-
tion with air, oxygen-enriched environments, or nitrous oxide.
►
To ensure safety, avoid stacking multiple devices or placing any
-
thing on the device during operation.
►
To protect against injury, follow the directions below:
– Avoid placing the device on surfaces with visible liquid spills.
– Do not soak or immerse the device in liquids.
– Do not attempt to sterilize the device.
– Use cleaning solutions only as instructed in this instructions for
use.
– Do not attempt to clean the device while monitoring a patient.
►
To protect from electric shock, always remove the sensor and com
-
pletely disconnect the pulse oximeter before bathing the patient.
►
If any measurement seems questionable, first check the patient’s vi
-
tal signs by alternate means and then check the pulse oximeter for
proper functioning. Follow the section entitled “Troubleshooting”.
►
Inaccurate SpO
2
readings may be caused by the following
conditions:
– Improper sensor application and placement
– Elevated levels of COHb or MetHb: High levels of COHb or Me
-
tHb may occur with a seemingly normal SpO
2
. When elevated
levels of COHb or MetHb are suspected, laboratory analysis
(CO
-
Oximetry) of a blood sample should be performed.
– Elevated levels of bilirubin
– Elevated levels of dyshemoglobin
