Reusable SPO2 Sensor User Manual

Intended Use & Indications for Use

This SpO2 sensor is indicated for continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). It is are fully compatible replacement sensors intended for use with major pulse oximeter brands. This SpO2 sensor is designed to match the specifications of the original equipment manufacturer, therefore confirm that the appropriate sensor model number is being used for each particular pulse oximeter technology.

Reusable sensors are available for the following patient sizes:

Adult (weight greater than 40 kg)
Adult Soft (weight greater than 40kg)
Pediatric (15-40 kg weight)
Pediatric Soft (10-50 kg weight)
Infant Soft (3-20 kg weight)
Neonate Soft (1-3 kg weight)
Multi-Site (All Patients)
Ear Clip (weight greater than 40 kg)

Principle of Operation

The sensors must be connected to its corresponding monitor. Blood oxygenation is measured by detecting the infrared and red light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient's finger. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions.

Installation

Connect the SpO2 sensor to the oximeter’s adapter cable.
Turn the oximeter on and verify proper operation.
Select the sensor site on the patient. The preferred sensor sites are the index finger, alternatively the thumb or little finger is recommended.
Apply the sensor on the patient.
Visually monitor the sensor site to ensure the integrity of the skin.

Caution

The sensor and its cable must be cleaned before each patient use.
Place the sensor on the index finger ensuring the finger is fully inserted and the tip of the finger rests against the finger stop inside the sensor.
Possible alternate sites are the small-sized thumb, middle and ring fingers as well as the little finger or the big toe.
Ensure the fingernail is located under the finger stop on the SpO2 sensor clamp.
The sensor must not be located on the same arm as the blood pressure cuff, arterial catheter or intravascular line.
Remove all nail polish as this can affect accuracy.
Do not use the sensor inside or near an MRI.
Avoid intense light sources near the sensor.
For long-term use, the measurement site must be checked and changed every 2-4 hours in order to guarantee the integrity of the patient’s skin.
In restless patients (excessive motion) use the soft tip, wrap or multi-site sensor to help secure the sensor to the patient.

Equipment

Connect the sensor cable to the appropriate equipment (pulse oximeter).
Turn equipment on and check correct operation by consulting the monitor’s operation instructions.
To ensure proper monitor operations, connect and disconnect the sensor cable from the monitor cable. The correct, safe use of the sensor and its connecting cable requires systematic checks to be carried out at least once or more per month depending on the frequency of use, as well as disinfecting the cable.
Visual check (appearance of insulators, connector contact pins, etc.)
Verify the mechanical integrity of the connectors.

Do not use and discard any sensor that appears to have any mechanical or electrical flaws.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic fields are affected by the absorption and reflection from structures, objects and people. The ISM (industrial, scientific and medical) bands are between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the reusable SpO2 sensor is used exceeds the applicable RF compliance level above, the reusable SpO2 sensor should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the reusable SpO2 sensor. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
