Monitoring (LX-7230N)

■

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.

NOTE

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.

NOTE

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.
