A pulse oximeter is a noninvasive method of monitoring oxygen saturation in the blood. Its readings are accurate to within 2% of arterial blood gas analysis. What makes it such a useful tool is its low cost. The simplest models can be bought online for as little as $100. For more information, see our Pulse Oximeter Review. Whether you’re planning to purchase a fingertip model or a more sophisticated one, here’s a quick overview of the features of these devices.
fingertip pulse oximeter
A fingertip pulse oximeter measures your heart rate and oxygen saturation through light absorption. The device is non-invasive, attaches to your fingertip with a gentle squeeze, and renders results in seconds. It is used to monitor various health conditions, including breathing disorders and overall health. Fingertip versions are increasingly used for relaxation and general wellness purposes. These units are easy to read and are ideal for children. A fingertip pulse oximeter is a convenient way to measure your SpO2, pulse rate, and other vital signs.
People with certain conditions that cause low oxygen levels may have symptoms prior to the appearance of the condition. A pulse oximeter can help detect COVID-19 early. Although not everyone who tests positive for COVID-19 develops low oxygen levels, symptoms of the infection may manifest themselves at home. If you notice these symptoms, seek medical attention. Even if you test negative for COVID-19, you might have an infection or even an infection.
A fingertip pulse oximeter measures the oxygen saturation of red blood cells and is painless. The fingertip device uses light-emitting diodes to send small beams of light through your finger. When the light reaches the sensors, it determines the red blood cell oxygen saturation, or SpO2.
