Problem Possible Cause Possible Solution

The unit will not turn on. The batteries are depleted. Replace all 4 batteries.

The batteries are installed

incorrectly.

Verify correct battery installation.

Metal contact in battery

compartment is missing or

damaged.

Contact Respironics Customer

Support.

A dash appears in the

left digit of the SpO

2

display.

A sensor fault exists. The

sensor may have become

dislodged from the 920M

PLUS or from the patient.

Verify that the sensor is correctly

connected to the 920M PLUS and

the patient; try a new sensor if the

condition persists.

The middle digits display

dashes in both the SpO

2

and pulse rate displays.

No signal is detected

because the sensor is not

plugged in.

Verify the sensor connections.

There is a sensor failure. Replace the sensor.

The displayed pulse rate

does not correlate to the

pulse rate displayed on

the ECG monitor.

Excessive motion at the

sensor site may be

preventing the 920M PLUS

from acquiring a consistent

pulse signal.

Eliminate or reduce the cause of

the motion artifact, or reposition

the sensor to a site where motion is

not present.

The patient may have an

arrhythmia, resulting in heart

beats that do not yield a

pulse quality signal at the

sensor site.

Examine the patient:

the condition may persist even

though both monitors are

functioning properly if the patient's

arrhythmia persists.

A non-Respironics sensor is

being used.

Replace the sensor with a

Respironics sensor.

The ECG monitor may not

be functioning properly.

Examine the patient: replace the

ECG monitor, or refer to the

operator's manual for the ECG

monitor.

An erratic pulse rate

display and/or a yellow

pulse quality indicator

during the concurrent

use of electrosurgical

equipment (ESU).

The ESU may be interfering

with the pulse oximeter

performance.

Examine the patient: move the

920M PLUS, cables, and sensors

as far away from the ESU as

possible or refer to the ESU

operator's manual.

The pulse quality

indicator is blinking

yellow with each pulse.

The quality of the pulse

signal at the sensor site is

marginal.

Examine the patient: reposition the

sensor or select an alternate

sensor site.
