Sensors
Note:
Failure to take this precaution in high ambient light
conditions may result in inaccurate measurements.
If patient
inoveinent presents a problem, try one or more of the
following
remedies to correct the problem.
verify that the sensor is properly and securely applied
move the sensor to
a
less active site
e
use an adhesive sensor that tolerates some patient motion
use a
new sensor with fresh adhesive backing
If poor perfusion affects
performaiice, consider using the
Oxisensor
R-
1
5
sensor; it obtains measurements froin the nasal
septa1 anterior ethmoid artery, an artery supplied by the internal
carotid. This sensor may obtain measurements when peripheral
perfusion is relatively poor.
For low peripheral
perhsioii, consider using the Nellcor
RS-
10
sensor, which is applied to the forehead or temple. These are
sites that
may be spared during peripheral vasoconstriction.
Note:
The preceding section pertains to
patient and
environmental
coilditions that can be addressed by sensor
selection
and application. For information regarding the
impact of other patient enviroimeiital conditions on
oximeter performance, see
"Performance
Considerations"
in
the
Start-Up
and
Use
section of this manual.
