•

Excessive patient motion;

•

Venous pulsations;

•

Intravascular dyes such as indocyanine green or methylene blue;

•

Defibrillation;

Other physiological conditions or medical procedures that may interfere with the monitor’s

measurements include significant levels of dysfunctional hemoglobin, low perfusion, and

dark pigment.

Loss of pulse signal can occur in the following situations:

•

The sensor is too tight;

•

A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor

attached;

•

There is arterial occlusion proximal to the sensor.

Select an appropriate sensor, apply it as directed, and observe all warnings and cautions

presented in the directions for use accompanying the sensor. Clean and remove any

substances such as nail polish from the application site. Periodically check to ensure that the

sensor remains properly positioned on the patient.

If patient movement presents a problem, try one or more of the following remedies to correct

the problem.

•

Verify that the sensor is properly and securely applied.

•

Move the sensor to a less active site.

•

Use an adhesive sensor that tolerates some patient motion.

•

Use a new sensor with fresh adhesive backing.

If poor perfusion affects performance, consider using the Oxisensor R-15 sensor; it obtains

measurements from the nasal septal anterior ethmoid artery, an artery supplied by the internal

carotid. This sensor may obtain measurements when peripheral perfusion is relatively poor.

For low peripheral perfusion, consider using the Nellcor RS-10 sensor, which is applied to

the forehead or temple. These are sites that may be spared during peripheral vasoconstriction.
