Prolonged continuous SpO
2
monitoring may increase the
risk of undesirable changes in skin characteristics, such as
irritation, reddening, blistering or burns.
Check the SpO
2
sensor application site every 6-8 hours to
determine the positioning of the sensor and the circulation
and skin sensitivity of the patient. Patient sensitivity varies
depending on medical status or skin condition. For patients
with poor peripheral blood circulation or sensitive skin,
inspect the sensor site more frequently.
Functional tester cannot be used to assess the accuracy of
a SpO
2
sensor or a device.
This device is designed to determine the arterial oxygen
saturation percentage of functional hemoglobin. Factors
that may degrade pulse oximeter performance or affect the
accuracy of the measurement include the following:
- excess ambient light
- excessive motion
- electrosurgical interference
- blood flow restrictors
(arterial catheters, blood pressure cuffs, infusion lines,
etc.)
- moisture in the sensor
- improperly applied sensor
- incorrect sensor type
- poor pulse quality
- venous pulsations
- anemia or low hemoglobin -concentrations
- cardiogreen and other -intravascular dyes
- carboxyhemoglobin
- methemoglobin
- dysfunctional hemoglobin
