CHAPTER 1 General Information

Oxygen saturation is a percentage of oxyhemoglobin (HbO2) capacity, compounded with oxygen, by all combinative hemoglobin (Hb) capacity in blood. In other words, it is consistency of oxyhemoglobin in blood. It is a very important parameter for the Respiratory Circulation System. Many respiratory diseases can result in low oxygen saturation in human blood. Additionally, the following factors can reduce oxygen saturation: Automatic regulation of organ dysfunction caused by Anesthesia, Intensive Postoperative Trauma, injuries caused by some medical examinations. That situation might result in light-headedness, asthenia, and vomiting. Therefore, it is very important to know the oxygen saturation of a patient so that doctors can find problems in a timely manner. The pulse oximeter integrated with Bluetooth® wireless technology is designed to monitor vital signs, such as SpO2 and pulse rate anytime, anywhere.

Measuring Principle

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 the display through process in electronic circuits and microprocessor.

CHAPTER 2 Settings

Configuring Your Pulse Oximeter

There are some settings which can be adjusted by software, including date and time, switching, real-time and non realtime data transmission modes, powering off, and updating the software of the pulse oximeter.

Selecting a Display Mode

You can adjust the display mode of your oximeter when performing SpO2 and pulse rate measurements, every time you press the button, the pulse oximeter will switch to another display mode. During the measuring, each time you press the button the oximeter will switch to another display mode, there are 4 display modes shown as below:

CHAPTER 3 Take a Measurement

• Open the clamp and insert a finger into the oximeter, as illustrated in the right figure. Then gently release the clamp.
• Make sure that the distance between you and other Bluetooth® device within 10m. (30 ft.)

• Press the power button, the display will light up and after a few seconds, the device will display SpO2% and pulse rate measuring values. The oximeter will also transmit the recorded information via Bluetooth® to other Bluetooth® device.
• After transmitting data to other Bluetooth® device, the oximeter will shut down automatically.

NOTES:

• Keep your tested hand still during the measurement.
• Do not pour or spray liquids onto the oximeter, and do not allow any liquid to enter any openings in the device. Make the oximeter dry thoroughly before reusing.
• The oximeter will shut down after a period of time if no measurement is being taken.
• Clean the rubber touching the finger probe inside of the pulse oximeter with a soft cloth dampened with 70% isopropyl alcohol, and cleans the test finger probe using alcohol before and after each measurement.
