Applying the OxiMax
®
MAX-I sensor
This Nellcor
®
adhesive sensor, model MAX-I, is indicated for continuous
noninvasive arterial oxygen saturation and pulse rate monitoring and can be
reused on the same patient as long as the adhesive tape attaches without
slippage.
1. Remove the plastic backing from the MAX-I and locate the two transparent
windows on the adhesive side. Windows cover optical components. Note
the corresponding alignment marks (a) on the non-adhesive side and the
dashed line (b) midway between the marks (Figure (1)).
The big toe is the preferred MAX-I location. Alternatively, apply the sensor
to another digit of similar size, for example, the thumb.
N O T E
When selecting the sensor site, priority should be given to an extremity free
of an arterial catheter, blood pressure cuff, or intravascular infusion line.
2. Orient the MAX-I so that the window next to the cable is aligned on the
bottom of the big toe as shown. The cable should extend towards the heel
(Figure (2)).
3. Wrap the MAX-I firmly, but not too tightly around the toe. Windows must
oppose each other for correct measurement (Figure (3)).
4. Wrap any excess tape loosely around the toe. Use additional tape
provided to secure the cable across the bottom of the foot, loosely enough
to maintain good circulation (Figure (4)).
5. Connect the MAX-I into the LX-7230N. Verify proper operation as
described in the operation manual.

N O T E
If the sensor does not track the pulse reliably, it may be incorrectly
positioned – or the sensor site may be too thick, thin, or deeply pigmented,
or otherwise deeply colored (for example, as a result of externally applied
coloring such as nail polish, dye, or pigmented cream) to permit appropriate
light transmission. If any of these situations occurs, reposition the sensor or
choose an alternate Nellcor sensor to use on a different site.
