 and special features

Use Nellcor™ sensors, which are specifically designed for use with the 
monitoring system. Identify Nellcor™ sensors by the Nellcor™ logo on the plug. 
All Nellcor™ sensors contain a memory chip carrying information about the 
sensor which the monitoring system needs for correct operation, including the 
sensor’s calibration data, model type, troubleshooting codes, and error 
detection data.

This unique oximetry architecture enables several new features. When a 
Nellcor™ sensor is connected to the monitoring system, the monitoring system 
reads the information from the sensor memory chip, ensures it is error free, and 
then loads the sensor data prior to monitoring for new information. As the 
monitoring system reads sensor information, it sends the sensor model number 
to the monitoring screen. This process may take a few seconds. The sensor 
model number disappears after the monitoring system starts tracking the 
patient’s SpO

 and pulse rate.

Any monitoring system containing OxiMax technology uses calibration data 
contained in the sensor in calculating the patient’s SpO

2

. With sensor calibration, 

the accuracy of many sensors is improved, since the calibration coefficients can 
be tailored to each sensor.

Contact Covidien or a local Covidien representative for a Sensor Accuracy Grid 
listing all of the sensors used with the monitoring system. Covidien retains a soft 
copy at www.covidien.com.

The monitoring system uses the information in the sensor, tailoring messages to 
better help the clinician troubleshoot client or data issues. The sensor 
automatically identifies its sensor type to the monitoring system when attached.

The monitoring system monitors the percentage of hemoglobin binding sites 
saturated with oxygen in the blood. With traditional alarm management, upper 
and lower alarm limits are set to alarm at specific SpO

2

 levels. When the SpO

2

 

level fluctuates near an alarm limit, the alarm sounds each time it violates the 
alarm threshold. SatSeconds monitors both degree and duration of desaturation 
as an index of desaturation severity. Thus, the SatSeconds parameter helps 
distinguish clinically significant events from minor and brief desaturations that 
may result in nuisance alarms.

Consider a series of events leading to a violation of the SatSeconds alarm limit.

An adult patient experiences several minor desaturations, then a clinically 
significant desaturation.
