Directions for use
and varies between monitoring sites and from patient to patient, as physiological
conditions vary.
Masimo displays the LofP as a numeric value and refers to it as Perfusion Index. Nonin
displays the LofP as a color value (yellow or red) only when the LofP is low, based on the
sensor's algorithm.
During sensor placement, the LofP can be used to evaluate the appropriateness of an
application site by looking for the site with the highest LofP number. Placing the sensor
at the site with the strongest pulse amplitude (the highest LofP number) improves
performance during motion. Monitor the trend of the LofP for changes in physiological
conditions.
SatSeconds™ alarm management
The SatSeconds feature is an SpO2 alarm management system available only with
monitors that are equipped with Nellcor
The SatSeconds feature is the product of the time and magnitude that a patient falls
outside of the SpO2 alarm limits. For example, three points below the alarm limit for 10
seconds equals 30 SatSeconds. An alarm is triggered only when a desaturation event
reaches the SatSeconds limit. The SatSeconds feature is clinician controlled and can be
set to 0, 10, 25, 50, or 100 SatSeconds. If a desaturation event resolves on its own
within the preset time, the clock will automatically reset and the monitor will not alarm.
Note
Interval SpO2 measurement
You must be in either the Intervals or Office profile to set intervals. Refer to the
"Intervals" section for directions on setting intervals. For a description of the effect on
displayed and transmitted SpO2 pulse rate values, refer to the SpO2 manufacture's
directions for use.
Measure SpO2 and pulse rate
The SpO2 sensor measures oxygen saturation and pulse rate. Oxygen saturation is
displayed as a percentage from zero (0) to 100%. The oxygen saturation and pulse rate
are updated and refreshed each second, ± 0.05 seconds.
The SatSeconds feature has a built-in safety protocol that sounds an alarm
whenever three SpO2 violations of any amount or duration occur within a
1-minute period.
WARNING Inaccurate measurement risk. Use only Masimo sensors and
accessories on Masimo-equipped monitors.
WARNING Inaccurate measurement risk. Use only Nellcor sensors and
accessories on Nellcor-equipped monitors.
WARNING Inaccurate measurement risk. Severe anemia may cause
erroneous SpO2 readings.
WARNING Inaccurate measurement risk. The pulse oximeter can be used
during defibrillation, but the readings may be inaccurate for up to 20
seconds.
