Patient Preparation; Applying The Sensor - Dräger Infinity Acute Care System M540 Instructions For Use Manual

Patient preparation

The following tips provide optimal SpO
results but must never replace hospital-approved
practices or manufacturer's recommendations.

If a finger is used as a monitoring site, remove any
nail polish. Cut the finger nails of the patient, if nec-
essary.
The signal may vary due to the following conditions:
– Placement of a sensor that is too tight
– Patient experiences hypotension, severe vaso-
constriction, severe anemia, or hypothermia
– Arterial occlusion proximal to the sensor
– Patient is in cardiac arrest or is in shock.
– Bright light causing erratic measurement or
missing values. Cover the sensor with opaque
material if it is likely to be exposed to direct
bright light.
– Significant levels of dysfunctional hemoglobins
(carboxyhemoglobin and methemoglobin)
– Intravascular dyes such as indocyanine green
or methylene blue
– Excessive patient movement
– Venous pulsations
– Placement of a sensor on an extremity with a
blood pressure cuff, arterial catheter, or intra-
vascular line
The maximum sensitivity mode for a Masimo MCa-
ble is recommended for patients with low perfusion
or when the low perfusion or low signal quality mes-
sage is displayed on the screen in APOD or normal
sensitivity mode. This mode is not recommended
for care areas where patients are not monitored vi-
sually, such as general wards. It is designed to in-
terpret and display data at the measuring site when
the signal may be weak due to decreased perfu-
sion.

the monitor detects low amplitude arterial pulsa-
tions. In this case, do the following:
1 Check the patient and treat if necessary.
2 Move the sensor to a site that is more ade-
quately perfused.
3 Select maximum sensitivity mode.

Applying the sensor

NOTE
Only use Masimo sensors with the Masimo SET
MCable and the Masimo rainbow SET MCable.
Read the instructions provided with the sensor for
optimal application techniques and for safety in-
formation. Never use damaged sensors.
If you are using a reusable sensor, make sure it is
clean before applying it to the patient. Follow the
recommendations of the manufacturer.
