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

SpO2 OxiMax

Technology.

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 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.

SpO2 waveform view

The waveform view shows the real-time SpO2 plethysmograph waveform. Authorized

personnel can select the waveform sweep speed in Advanced settings.

For additional normalization and waveform information, refer to the manufacturer's

Directions for use.

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.

WARNING Inaccurate measurement risk. Use only Masimo SET or MX-5

sensors and accessories on Masimo-equipped monitors.

WARNING Inaccurate measurement risk. Use only Nellcor sensors and

accessories on Nellcor-equipped monitors.
