Simple and Convenient Healthy Tool! The all-digital fingertip pulse oximeter is designed for noninvasive point control measurement of functional oxygen saturation of arterial hemoglobin (SpO2) and heart rate. The pulse oximeter is a device that provides continuous information about the peripheral oxygen saturation (SpO2) rate noninvasively. This device is used in the detection of hypoxemia due to its ability to detect changes in hemoglobin oxygen saturation. When you place your fingertip in the chamber, your oxygen saturation will be displayed in a few seconds. With the simple press of a button, you can take measurements anywhere, anytime and anytime in a convenient and hygienic way! The screen rotates in 4 directions so it can be easily read from any angle. The alarm can be set high and low for blood oxygen and heart rate. Accurately receives pulse and hemoglobin oxygen levels Designed to block ambient light from reaching the sensor, significantly increasing the signal-to-background ratio and accuracy of measurement. Displays results in real time with numbers, waveform and bar graphs to easily see pulse rate, pulse strength and oxygen levels. Gives a visual indication of an irregular, weak heartbeat or misreading. Internal alarm can be set high and low. There was no statistically significant difference between the measurements taken by the devices used. The mean of the comparative analysis presented by the instruments was 0.2337 ą 0.4355 (mean ą SD), indicating a strong correlation between the results obtained. According to the research methodology, the PPO has an accuracy similar to the traditional hospital oximeter with a digital sensor. PPO can be used in dental treatments.
