Pulse Oximeter A2

pulse oximeter | very useful and important thing which we need so now you also get benefit from and order now pulse oximeter.

Pulse oximetry is a noninvasive method for monitoring a person’s oxygen saturation. Peripheral oxygen saturation (SpO₂) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (SaO₂) from arterial blood gas analysis. But the two are correlated well enough that the safe, convenient, noninvasive, inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use.

The most common approach is transmissive pulse oximetry. In this approach, a sensor device is placed on a thin part of the patient’s body, usually a fingertip or earlobe, or an infant’s foot. Fingertips and earlobes have higher blood flow rates than other tissues, which facilitates heat transfer. The device passes two wavelengths of light through the body part to a photodetector. It measures the changing absorbance at each of the wavelengths, allowing it to determine the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) nail polish.

• The A2 pulse oximeter uses the latest oxygen sensor technology to accurately determine the level of oxygen in blood (SpO2) in 8 seconds. The measurement range is 70% – 99% with ±2% accuracy and ±1% of resolution. A2 finger pulse oximeter fits all finger sizes and provides 6,000 spot checks. Please check original images

• 【FAST AND ACCURATE MEASUREMENT】 pulse oximeter adopts advanced technology to provide reliable results. It can measure SpO2 and pulse rate, giving throughout inspection of your body.
• 【EASY TO USE】 Just put your finger into hole( Equipped with Glow and infrared-ray Emission and Receipt Tube) After 5s, the results of oxygen saturation will be seen clearly on the LCD screen. It automatically shuts off when no use in 5 seconds to preserve battery life.
• 【AUTO 4 DIRECTIONS DISPLAY, MORE CONVENIENT】 Due to bulit-in gravity sensor, values can be automatically displayed in 4 directions as your finger moves. Much more convenient for daily use. What’s more, You can adjust the screen brightness to meet your needs.
• 【COMPACT AND PORTABLE】 This pulse oximeter comes with a nylon sheath for outdoor usage. Package also includes 2*AAA batteries. Once you get our product, you can use at once!
