Fingertip Pulse Oximeter V2.0C318 3 Safety Information Please read this manual thoroughly before using the pulse oximeter! Keep it in hand for future reference. Warnings alert the user to potential serious outcomes, such as injury or adverse events to the patient or user. Cautions alert the user to exercise care necessary for the safe and effective use of the pulse oximeter. Notes contain important information that may be overlooked or missed. Warnings! ● DO NOT strike or needle the battery. ● Keep away from source of fire and/or heat. ● DO NOT disassemble the oximeter or its accessories. ● DO NOT use the pulse oximeter in an MRI or a CT environment ● DO NOT use the pulse oximeter in the presence of flammable anesthetics. ● Explosion hazard: DO NOT use the pulse oximeter in an explosive atmosphere. ● Chemicals from a broken OLED panel are toxic when ingested. Use caution when the oximeter has a broken display screen. ● The pulse oximeter is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms. ● Check the pulse oximeter application site frequently to determine the positioning of the measurement and circulation and skin sensitivity of the patient. ● Although the pulse oximeter has alarms, it is not suggested for long time continuous monitoring.
Fingertip Pulse Oximeter V2.0C318 4 ● Prolonged use or the patient’s condition may require changing the measurement site periodically. Change measurement site and check skin integrity, circulatory status, and correct alignment at least every 4 hours. ● Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries. ● Only the authorized service personnel can replace the battery or repair this device. This device uses a fixed lithium-ion battery inside. Do not try to replace the battery by yourself at any time. For longer battery life, only charge the battery when the battery power is empty. Cautions! ¾ Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid may cause inaccurate readings. ¾ Significant levels of dysfunctional hemoglobins (such as carbonxy- hemoglobin or methemoglobin) may cause inaccurate readings. ¾ Intravascular dyes such as indocyanine green or methylene blue may cause inaccurate readings. ¾ SpO2 measurements may be adversely affected in the presence of upper ambient light. Shield the sensor area (with a surgical tower, or direct sunlight, for example) if necessary. ¾ Excessive patient movement may cause inaccurate readings. ¾ Upper-frequency electrosurgical interference may cause inaccurate readings.
Fingertip Pulse Oximeter V2.0C318 5 ¾ Venous pulsations may cause inaccurate readings. ¾ Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line may cause inaccurate readings. ¾ The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia may cause inaccurate readings. ¾ Operation of the pulse oximeter may be affected by the use of an electrosurgical unit (ESU). ¾ The pulse oximeter must be able to measure the pulse properly to obtain an accurate SpO2 measurement. Verify that nothing is hindering the pulse measurement before replying on the SpO2 measurement. ¾ The patient is in cardiac arrest or is in shock may cause inaccurate readings. ¾ Fingernail polish or false fingernails may cause inaccurate SpO2 readings. ¾ Federal Law (U.S.A) restricts this device to sale by or on the order of a physician. ¾ All Choice devices are designed to be complied with rules and regulations in locations they are sold and will be label as required. ¾ Any changes or modifications to choice equipment, not expressly approved by choice, could void the user’s authority to operate the equipment.

Fingertip Pulse Oximeter V2.0C318 7 CHAPTER 1 General Information The pulse oximeter is integrated with Bluetooth® technology allowing the user to transfer measurement data any time and anywhere. The oximeter is designed with the measurement, storage, review, audible and visible alarms, vibration alert and data transmission function (optional). Note:The illustrations used in this manual may differ slightly from the appearance of the actual product. 1.1 Measuring principle Principle of the oximeter is as follows: An experience formula of data process is established taking use of Lambert Beer Law according to Spectrum Absorption Characteristics of Reductive hemoglobin(HbR) and Oxyhemoglobin (HbO2) in red light and near-infrared light zones. The photoelectric oxyhemoglobin inspection technology is adopted in accordance with capacity pulse scanning and recording technology, so that two beams of different wavelength of lights (660nm red light and 940nm near infrared light) can be focused onto human nail tip through perspective clamp finger-type sensor. Then measured signal can be obtained by a photosensitive element, information acquired through which will be shown on two groups of LEDs through process in electronic circuits and microprocessor.

Fingertip Pulse Oximeter V2.0C318 30 CHAPTER 10 Maintenance And Calibration 10.1 Please charge the battery timely when the power low indicator flashes. 10.2 Clean the surface of the fingertip Oximeter before it is used in diagnosis for patients. 10.3 It is best to preserve the product in the environment specified in this manual. 10.4 It is recommended that the product should be kept in a dry environment anytime. A wet ambient might affect its lifetime and even might damage the device. Please follow the law of the local government to deal with used oximeter and the accessories. Cleaning the PULSE OXIMETER: ¾ Please use 70% isopropyl alcohol to clean the inside surface of the probe. ¾ Moisten a soft cloth with the alcohol and clean the finger probe, before and after each test. ¾ Do not pour or spray liquids onto the oximeter or probe, and do not allow any liquid to enter any gaps in the device or probe. ¾ In case moisture enters the oximeter or probe, be sure to dry thoroughly before reuse. Calibration: The functional tester cannot be used to assess the accuracy of the oximeter. The test methods used to establish the SpO2% accuracy is clinical testing. The oximeter used to measure the arterial haemoglobin oxygen saturation levels and these levels are to be compared to the levels determined from arterial blood sampling with a CO-oximeter. Index 2 that made by Bioteck company is a function tester. Set Tech to 1, R curve to 2, then user can use this particular calibration curve to measure the oximeter.
Fingertip Pulse Oximeter V2.0C318 31 CHAPTER 11 Troubleshooting Problem Cause Solution SpO2% or pulse rate does not display. 1. Finger is not plugged correctly. 2.
