Understanding Pulse Oximetry

Selecting a Sensor

The most important factor when selecting a sensor is the position of the light emitting diodes in
relation to the photodetector. When the sensor is applied, the diodes and the photodetector must be
opposite each other. Sensors are designed for patients with a specific weight range and for specific
sites. Be sure to:
Select a sensor appropriate for the patient's weight.
Select a sensor site with adequate perfusion.
Avoid application to sites with edematous tissue.
SpO
sensors are either reusable or disposable. Reusable sensors can be reused on different patients
2
after they have been cleaned and disinfected (see the manufacturer's instructions supplied with the
sensor). Disposable sensors should only be used once and then discarded. They may be relocated to
another appropriate site on the same patient but not reused on different patients.

Table 57 "Approved Supplies and Accessories"
accessories that can be used with the Efficia DFM100.
CAUTIONS: Do not use more than one extension cable (M1941A).
Do not use the ear transducer on patients with small ear lobes as incorrect measurements may result.

Applying the Sensor

Follow the manufacturer's directions for applying and using the sensor, making sure to observe any
warnings or cautions. For best results:
Make sure the sensor is dry.
If the patient is moving, secure the sensor cable loosely to the patient.
Make sure the sensor is not too tight. Too much pressure can cause venous pulsation or can
impede blood flow, resulting in low readings.
Keep power cables away from the sensor cable and connection.
Avoid placing the sensor in an environment with bright lights. If necessary, cover the sensor with
opaque material.
Avoid placing the sensor on an extremity with an arterial catheter, blood pressure cuff or
intravenous infusion line.
WARNINGS: Failure to apply the sensor properly may reduce the accuracy of the SpO
Inspect the sensor application site at least every two hours for changes in skin quality, correct optical
alignment and proper sensor application. If skin quality is compromised, change the sensor site.
Change the application site at least every four hours. More frequent checking may be required due to
an individual patient's condition.
Do not use a damaged sensor or one with exposed electrical circuits.
