Intended use

Accurate disposable SpO2 sensors are indicated for single-patient use and are intended for continuous noninvasive arterial oxygen saturation(Sp02) and pulse rate monitoring.  Accurate disposable Sp02 sensors are designed to match the specifications of the original manufacturer’s equipment.  It is important to get compatibility information from the product labels and/or Accurate Company while selecting proper sensors and extending cables to match the equipment.

• Product usage period: Disposable
• Product storage period: 3 years
• Users: adult； neonate；
• Model： AF543-01，AF543-01X

Product Overview

Accurate disposable Sp02 sensors are classified into the following categories: adult and neonate foam adhesive(AF543 series)type.

Warning: 

• Accurate disposable SpO2 sensors are for use with pulse oximeters.
• Check the compatibility of the equipment, sensor and extended cable before use.
• Incompatible components can result in degraded accuracy and performance.
• Select the appropriate sensor type to avoid inaccurate measurements or even harmful events that may lead to serious patient injury.
• In the event of the packaging being damaged, do not use the sensor.
• The disposable SpO2 sensor is intended for single-patient use and has been cleaned before delivery. Do not attempt to clean or sterilize it, otherwise it may result in product failure.
• Try to keep the patient still and avoid excessive motions at the measured site.
• Do not locate the sensors on the same arm as the blood pressure cuff, arterial catheter or intravascular line if using any of those devices at the same time.
• Make sure the measured site is not deeply pigmented or deeply coloured, otherwise inaccurate measurement will occur.
• For long-term use, the measurement site must be changed every 4 hours to avoid skin damage.
• The measurement may be inaccurate with very low perfusion at the measured site.
• Prevent the sensors from being under the condition of strong light and irradiation field, otherwise inaccurate measurement will occur.
• Do not use the sensor inside or near an MRI equipment.
• Do not immerse the sensors in any of the cleaning solutions, disinfectants, or other liquids.
• Portable and mobile RF communications equipment can affect measurement accuracy.
• Do not place the sensors in an environment that exceeds the storage range.
• A functional tester or oximetry simulator cannot be used as the assessment tool for the accuracy of sensors.
• Disposal of the sensor shall comply with local regulations.
• Don’t near active HF surgical equipment and the RF-shielded room of an ME system for magnetic resonance imaging, where the intensity of EM disturbances is high.
• Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.
• Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.”
• Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of theequipment, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.

Sensor applications

Before applying sensors

• Be sure to read, understand and observe all warnings listed in this manual and the manual of pulse oximeters. 4.2 Selecting appropriate sensors for different patients
• Adult-type sensors suit for adult patients(weight:>30 Kg); neonatal-type sensors suit for neonatal patients(weight:<3 Kg).

Applying sensors Neonate/Adult Foam Adhesive

1. Place the sensor on the patient as shown below.
   • Neonate: Place the sensor on the patient’s toe or finger as shown below with optical components opposite each other.

Adult

1. Place the sensor on the patient’s finger as shown below with optical components opposite each other. Be sure that the side with LED is above the nail. The index finger is the best site, and other fingers except the thumb can be considered either when the index finger is not available or cannot be located correctly.
2. Holding the sensor and stretching the strap slightly.
3. Connect the sensor to pulse oximeters (with an extended cable if needed).
4. Inspect and change the measurement site periodically.

Applying pulse oximeters

• Operate pulse oximeters under the instruction manuals.

Electromagnetic environment – guidance
RF wireless communications equipment should be used no closer to any part of the device, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance

Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range b. Interference may occur in the vicinity of equipment marked with the following symbol: ()
