2.4.3.1 Masimo SET
®
SpO
2
The Masimo pulse oximeter determines SpO
2
in the traditional manner of passing red and
infrared light into a capillary bed and measuring changes in light absorption during the
pulsatile cycle. It assumes that arterio-venous shunting is highly variable and that fluctuating
absorbance by venous blood is the major component of noise during the pulse. The Masimo
pulse oximeter calculates the ratio of the arterial signals without the noise.
Masimo SET provides a family of sensors suitable for a wide variety of clinical settings and
patient sizes. All sensors are:
• Indicated for continuous non-invasive monitoring of arterial oxygen saturation (SpO
2
)
and Pulse Rate
• Non-sterile
• Usable during patient movement
The LNOP®•DCI Adult Reusable Finger Sensor can be used for “spot check” applications if
needed. Adhesive-type sensors are also available. Refer to "Accessories" on page 5-1 for
approved sensors. All sensors are intended for “single-patient use only” unless indicated as
“reusable”.
CAUTION: When equipped with Masimo SpO2, use only Masimo
oxygen sensors and cables. Use of other oxygen sensors
may cause improper oximeter performance.
NOTE: Refer to instructions included with each SpO
2
sensor and
cable for proper placement and use.
1. Select an SpO
2
sensor that is appropriate for the size of the patient.
2. Attach the connector of the SpO
2
sensor to the SpO
2
extension cable.
3. Attach the SpO
2
sensor to the patient’s finger (or other appropriate site).
4. Orient the connector on the end of the SpO
2
extension cable so that the Masimo SET
logo is facing upward. Plug the connector into the SpO
2
receptacle on the right side
panel of the Trio. The SpO
2
measurement will display when the Trio detects that the
sensor is connected to the patient. A plethysmogram will be displayed to the left of the
SpO
2
parameter tile (if SpO
2
is selected in the TRACE SETUP menu).
NOTE: To disconnect the cable from the Trio, squeeze the tabs on
the sides of the connector and then pull it straight out.
CAUTION: Prolonged and continuous monitoring may increase the risk
of skin erosion and pressure necrosis at the site of the
sensor. Check the SpO2 sensor site frequently to ensure
proper positioning, alignment and skin integrity at least
every eight (8) hours; with the Adult and Pediatric re-usable
finger sensor, check every four (4) hours; for patients of
poor perfusion or with skin sensitive to light, check every 2
- 3 hours; more frequent examinations may be required for
different patients. Change the sensor site if signs of
circulatory compromise occur.
