SpO2 Safety Information
Always confirm monitor observations with clinical observation of the
patient before administering interventions.
Prolonged, continuous monitoring can increase the risk of changes in
skin characteristics, such as irritation, reddening, blistering or pressure
necrosis, particularly on patients with impaired perfusion and varying
or immature skin morphology. Specific attention must be given to
sensor site inspection for changes in skin quality, proper optical path
alignment and attachment. Check the application site at regular
intervals and change the site if any compromise in skin quality should
occur. More frequent checking can be required due to an individual
Injected dyes such as methylene blue or intravascular dyshemoglobins
such as methemoglobin and carboxyhemoglobin can lead to inaccurate
Interference leading to inaccurate measurements can be caused by:
High levels of ambient light (Hint: cover application site with
Excessive patient movement and vibration.
This equipment is not suitable for use in the presence of a flammable
anesthetic mixture or oxygen concentrations greater than 25% (or partial
pressures greater than 27,5 kPa /206.27 mmHg).
sensors can be damaged and lead to patient harm if
they become wet. Wet sensors must be replaced immediately.
To avoid venous pulsation, obstructed circulation, pressure marks,
pressure necrosis, artifacts and inaccurate measurements, make sure
that the sensor is not too tight. If the sensor is too tight, because the
application site is too large or becomes too large due to edema,
excessive pressure may be applied. This can result in venous congestion
distal from the application site, leading to interstitial edema, hypoxia
and tissue malnutrition.
Inspect the sensor application site every 2 to 3 hours to ensure skin
integrity, correct optical alignment, and circulation distal to the sensor
site. Move the sensor application site every four hours, or more often if
circulation or skin integrity is compromised.
