Monitoring

Applying the OxiMax

MAX-R sensor

This Nellcor

adhesive sensor, model MAX-R, is indicated for continuous

noninvasive arterial oxygen saturation and pulse rate monitoring. The MAX-R

is designed for use only on the nose. Use this sensor when finger pulsatile flow

is inadequate, or monitoring a finger/toe is not possible.

1. Clean the bridge of the patient’s nose with the contents of the enclosed

acetone/alcohol ampule to remove skin oils. Do not allow the

acetone/alcohol solution to get in the patient’s eyes.

2. Remove the plastic backing from the MAX-R and locate the transparent

windows on the adhesive side. Windows cover optical components. Note

the corresponding alignment marks on the non-adhesive side (a) and the

dashed center line (b) midway between the marks (Figure (1)).

3. Orient the MAX-R so that the dashed line is centered on the nose (a) and

the alignment marks are at the bone-cartilage junction (b). The cable

should extend toward the patient’s right side (Figure (2)).

4. Press the MAX-R firmly onto the nose and hold in place for 10 seconds to

ensure adhesion (Figure (3)). The MAX-R must be secured firmly for

proper operation.

5. As with all medical equipment, carefully route cables to reduce the

possibility of patient entanglement or strangulation.

6. Connect the MAX-R 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

to permit appropriate light transmission. If any of these situations occurs, try

another MAX-R or choose an alternate Nellcor Puritan Bennett sensor.
