OXITEST PLUS 7 OPERATING MANUAL
2) Ohmeda (Datex) Style
The Ohmeda style sensor uses a harder rubber-like material to surround the finger, taking the
finger shape into consideration with a depression in the material. The outside of the sensor is
commonly a hard plastic, molded in the shape of a clothes pin. Examples of this type include
Ohmeda, SiMed and Physio-Control finger clip sensors. The depression of the Ohmeda finger
clip sensor can be seen in
Figure 7
.
With the LEDs shining toward you, as in the Nellcor example, place the sensor on the test probe
so that the upper bulge on the probe fits into the sensor depression. Allow the sensor to close,
maintaining intimate contact between the photodetector side of the sensor and the upper side of
the test probe.
It is important to retain the tight, intimate contact on the photo-detector
side to prevent leakage of light from the sensor LEDs on the bottom reaching the
photodetector on the top.
As with the Nellcor-style sensor, a stiff sensor cable or long strain relief can be pre-formed
before the sensor is applied to the
Oxitest Plus 7
, and the cable routed via the probe
compartment before leading off to the oximeter under test.
Other sensor styles may also require careful placement:
