relative absorption of the two light wavelengths to compute and display SpO
saturation) and Pulse Rate measurements.
The key benefits of the sensors are:
·
Electro-Surgical Noise (ESU) Rejection - The sensor configuration of both the
DATASENSOR and the FLEXISENSOR
absence of false alarms during the use of ESU (ESU can be set at any power level). This
design prevents electro-surgical noise entering the monitor, via the sensor, and interfer-
ing with unit operation.
·
Monitoring Restless Patients - Motion artifact rejection is achieved in several ways.
·
Tracking of Weak Peripheral Pulse Levels - Many patients suffer poor peripheral
perfusion due to hypothermia, hypovolemia, reduced cardiac output, etc. The Accutorr
Plus model with SpO
poor peripheral perfusion.
·
Rejection of Ambient Light - Many monitoring situations involve high levels of
ambient light, i.e.., operating room lights, neonatal phototherapy, heat warmers, etc. The
Accutorr Plus model with SpO
rejection of ambient light. The monitor automatically measures and corrects for high
levels of ambient light. The enclosed design of the DATASENSOR prohibits the interference
of high levels of ambient light on adults with sensor operation. The opaque material used
in the composition of the bandages, which are used with the FLEXISENSOR
keep out ambient light.
·
Patient Comfort - The FLEXISENSOR
bandage of two styles (SENSOR GUARD TM and Coban) which conform comfortably
and safely to the particular patient's anatomy.
B. Sensor Selection and Application
Selection of a specific sensor is based on the patient's size, physical condition, and expected
monitoring duration. General guidelines for the selection of a sensor are provided in the
Sensor Selection Table, page 3-25. Instructions for the application of a sensor to a patient
are provided in each sensor package. For optimal DATASENSOR and FLEXISENSOR
placement ensure that cable side is placed in the correct position. See figures below.

1. The sensor design used with their recommended bandages assures a snug fit of
the sensor to the patient.
2. Light emitting diodes (LEDs) and detectors gather a strong signal from the patient.
3. When in the presence of motion, the software adjusts the "averaging-period",
increasing it to a maximum of 15 seconds during motion, and automatically
reducing it during quiet periods to obtain a fast response. This combination
reduces the number of monitoring interruptions and false alarms from patient motion.
