SPO2 SAFETY CONSIDERATIONS

Safety Considerations
WARNING:
z Use only sensors approved by Dräger Medical (see the
appendix Options and Accessories). Other sensors may
not provide adequate protection during defibrillation.
z Use only Masimo-compatible sensors and cables with
the Masimo SET pod.
z During electrosurgery, use only Dräger SpO
2
shielded
extension cables with a blue locking mechanism to
protect from ESU interference.
z Check sensors periodically (recommended is at least
every four hours). Move the sensor if there is any sign of
skin irritation or impaired circulation.
z Bright light can interfere with pulse oximetry
measurements, causing erratic or missing values. When
the sensor is likely to become exposed to direct bright
light, it should be covered with an opaque material.
z Elevated levels of carboxyhemoglobin or methemoglobin
in monitored patients or the presence of substances
containing dyes can result in inaccurate pulse oximetry
readings.
z If the monitor detects an SpO
2
and/or PLS Weak Signal
condition during an NBP measurement, the audible and
visual alarms for the Weak Signal condition are
suppressed. However, the monitor announces all other
SpO
2
/PLS conditions as they occur.
z A pulse oximeter should not be used as an apnea
monitor.
z Difficulties inherent in SpO
2
monitoring require that
patients receive special attention during electrosurgery
(ESU). To minimize interference from the ESU, do the
following:
- Place the SpO
2
sensor as far from the surgical site as
possible.
- Place the SpO
2
cables as far from the ESU as possible,
and perpendicular to the ESU cables.
- Use an ESU neutral electrode with the largest possible
contact area.
- When possible, place the ESU neutral electrode close
to and directly under the surgical site avoiding bony
protuberances. If this is not possible, interference
from the ESU may result.
- Consult the operating instructions of your
electrosurgical equipment for additional information.
