The key benefits of the sensors are:
• Electrocautery Noise (ESU) Rejection - The sensor configuration of both the
DATASENSOR and the FLEXISENSOR® SD provide uninterrupted monitoring and
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 interfering
with unit operation.
• Monitoring Restless Patients - Motion artifact rejection is achieved in several ways.
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.
Software in the Passport evaluates the shape of each pulse and automatically rejects
noisy and unreliable pulses.
4. 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.
•
Tracking of Weak Peripheral Pulse Levels
- Many patients suffer poor peripheral
perfusion due to hypothermia, hypovolemia, reduced cardiac output, etc. The Passport is
designed to automatically increase its gain to track patients with 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
PASSPORT Monitor, sensors, and bandages each contribute to the 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. And the opaque material used in the
composition of the bandages, which are used with the FLEXISENSOR® SD, helps keep
out ambient light.
• Patient Comfort - The FLEXISENSOR® SD line is designed to work with a disposable
bandage of three styles (SENSOR GUARD™, Coban and LIGHTGUARD™) 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
Table 1-7 on page 1-38. Instructions for the application of a sensor to a patient are provided
in each sensor package.
C. Sensor Connection to the Passport Monitor
1.
Align the cable connector on the sensor assembly with the SpO
2
Patient Connector (25)
on the Passport Monitor.
2. Push the cable connector into the SpO
2
Patient Connector (25). Confirm that the cable
connector is securely in place.
NOTE: To obtain maximum cable use, do not twist the cable
connector when attaching to or disconnecting from the
Passport Monitor.
