Bistos 4.3" Color Touch Screen Handheld Pulse Oximeter, BT-710. The Bistos BT-710 is a handheld pulse oximeter with a 4.3" color LCD touch screen. It provides an accurate SpO2 reading during motion and low perfusion. It comes with PC software for data analysis. The rechargeable built-in lithium battery provides 8 hours of continuous operation and easy charging with the pulse oximeter's mini USB port. It is suitable for adult, pediatric, and neonatal patients.

SpO2 Overview
Blood oxygen saturation (SpO2) is the percentage of oxyhemoglobin (HbO2) capacity bound by oxygen in the blood in the total hemoglobin (Hb) capacity that can be combined, that is, the concentration of oxygen in the blood. The principle for monitoring the pulse SpO2 is to fix the probe fingerstall on the patient’s finger, use the finger as a transparent container for hemoglobin, use 660nm wavelength red light and 905nm near-infrared light as the incident light, maximum output power is 300 mW, measure the light transmission intensity through the tissue bed, and calculate the concentration of hemoglobin and SpO2. The passing lights depend on a variety of factors, most of which are constant. However, one of these factors, the arterial blood flow, changes with time, as it is pulsating. By measuring the light absorbed during pulsating, it is possible to obtain the arterial blood SpO2.
Detection pulsation can give a “plethysmography” wave and pulse rate signal. BT-710 Operation manual P/N: 710-ENG-OPM-EUR-R02 Bistos Co., Ltd. 2020.03 18 The main screen displays the “SpO2” value and “plethysmography” wave. While the monitor gets and displays the physiological signal from a patient, the pulse tone which is the auditory information signal. The volume of this pitch tone is user-adjustable. This pulse oximeter applies to measure SpO2 of adults (>18 years), pediatric (<18 years,>30 days), and neonates (<30 days). Contact the SpO2 probe to the Patient’s finger to get the “SpO2” value and “plethysmography” wave.

Features of Bistos Hand-Held Pulse Oximeter
• 4.3" Color Touch Screen
• High Accuracy SpO2 reading
• Handheld Design

Essential performance
The pulse oximeter provides vital signs, including Pulse rate (PR), Blood oxygen saturation (SpO2), Perfusion index (PI), and Sensors are placed at the appropriate site on the patient to gather readings.

The device is composed of the following components: Display, Control circuit, panel, and Input part for SpO2 sensors.

Functionality: SpO2 and PR are detected using specific sensors, the detected analog signal is amplified and converted to a digital format, and the digital data is fed to the CPU and converted to display format, showing both numerical values and waveform.

Alarm System: The device includes an alarm system. An alarm is generated when the detected signal range exceeds the user-set alarm limits.

Monitoring steps
• Act the appropriate SpO2 sensor according to the patient.
• Turn on the pulse oximeter, and connect the SpO2 sensor probe to the pulse oximeter.
• Clean the measurement site, such as the finger with nail polish.
• Put the SpO2 sensor probe on the patient’s finger.
• Select the appropriate alarm settings.
• Start monitoring.

Battery
The pulse oximeter has a built-in rechargeable battery to ensure that the pulse oximeter can also be used normally in case of patient transfer or power failure. When the oximeter is connected to a DC power source, it will charge the battery no matter whether the pulse oximeter is turned on or not. In the case of power failure, the system will automatically use the battery to power the pulse oximeter to avoid interrupting the pulse oximeter working.
