Warning Warning
Failure to apply a sensor properly can reduce the accuracy of the SpO
measurement.
Loose/Tight sensor: If a sensor is too loose, it can compromise the optical
alignment or fall off. If it is too tight, for example because the application site is
too large or becomes too large due to edema, excessive pressure can be applied.
This can result in venous congestion distal from the application site, leading to
interstitial edema, hypoxia and tissue malnutrition. Skin irritations or
ulcerations can occur as a result of the sensor being attached to one location for
too long.
To avoid skin irritations and ulcerations, inspect the sensor application site
every 2-3 hours, and change the application site at least every 4 hours or
according to clinical practice guidelines.
Venous Pulsation: Do not apply sensor too tightly as this results in venous
pulsation, which can severely obstruct circulation and lead to inaccurate
measurements.
Ambient Temperature: Never apply an SpO
o o
above 37 C (99 F) because this can cause severe burns after prolonged
application.
Extremities to Avoid: Avoid sites distal to BP cuff, intra-arterial line, or
intravascular venous infusion line.
• Avoid sites with impaired perfusion, skin discoloration, excessive motion
or nail polish.
