Fingertip Pulse Oximeters: How These Small Devices Could Aid in the Battle of Coronavirus and More

As the Covid-19 is spreading steadily, how to stay safe is a big question. In this scenario, the devices like pulse oximeters have gained popularity as they can help in the monitoring of COVID-19 symptoms in earlier stage. Do you want to know more about these small and inexpensive devices and how they work, please read the shared detail below;

COVID-19 crisis presents many difficulties and uncertainties in humans’ life. None of medicine or device can completely eradicate the risk of it but the technologies like pulse oximeters and thermometers are in use worldwide against this pandemic as diagnostic tools. These tools are doing great job in early screening as they might signal about the risk of Coronavirus before you realize. As a result, these small devices are becoming an inexpensive part of everyday life. Oximeter could be one of the most commonly used technologies in the fight of coronavirus. By using this small device, you can get to know if you have Covid-19 symptoms or not so that accordingly you can then go for further testing for the confirmation and identification of high-risk of corona virus.

What’s a Pulse Oximeter

Anyone who is suspected to have coronavirus can have pulse oximeter monitoring even before Covid-19 testing. This is a small device that helps you to check the level of your blood oxygen and heart rate painlessly anytime, anywhereThis handy device can be clipped easily on the tip of your finger, ear, nose or toe to have a quick look of oxygen within your blood.

It measures the level of oxygen saturation in the blood and how it is sent into the different parts of your body. It helps to determine heart rate, oxygen saturation, arterial oxygen saturation (pulse oximetry), perfusion index and other vital signs that have a relationship with any serious illness.

How Pulse Oximeter Detects COVID-19 Symptoms

Not exactly, but a pulse oximeter warns if you have coronavirus symptoms. Many COVID patients feel shortness of breath as their blood oxygen level drops to a dangerously low level. This condition could be hazardous as it may damage the lungs.  COVID-19 patients feel shortness of breath because when the sacs of lungs are inflamed by any virus, it makes difficult to breathe. A small amount of oxygen in the lungs resulting low blood transfer to every body organ and this condition called hypoxia that might cause organ failure or individual death. The pulse oximeter measures the oxygen level in the blood which could be useful to assess Coronavirus symptoms earlier. Earlier analysis means earlier treatment which leads to positive results, if not than this disease increases the risk of death. In addition, taking oxygen reading continuously is also again important as it helps you to determine whether you are improving or declining. Therefore, pulse oximeter has become a must-have device in all conditions.

How Does It Work

When you clip it to your finger, a beam of shining light passes through your skin to notice the colour and movement of your blood cells. This painless process determines blood saturation level and heart rate by noticing changes of light absorption in the blood. If blood cells are bright red, it means they are oxygenated but if they are dark red it means they are deoxygenated. The pulse oximeter compares red and black cells to find out oxygen saturation percentage and heart rate.

Alarming Oxygen Level & Heart Rate

Once the pulse oximeter finishes measurement, it displays results. In normal conditions, the oxygen level reading falls between 95-100 per cent but in serious health conditions, this value may fall out of this range. Covid-19 patients oxygen level falls below to 50 % in alarming conditions. While a normal resting heart rate falls between 60 -100 BPM but it could be alarming if the value is higher as this indicates the cardiovascular system is deteriorating.

Accuracy & Precision: That Defines a Pulse Oximeter

Apart from easy applicability and portability, accuracy and precision are two important factors to consider when thinking of buying a pulse oximeter. Both these factors should be considered on priority to ensure the exactness of the results. To find a highly accurate pulse oximeter is difficult as a plethora of options (low to high cost) is available in the market from various brands and manufactures and they all claim accuracy with every reading. Do not fall for these fake claims; just choose a branded pulse oximeter that should have hospital-grade technology and features. It should have approved by the FDA for standards and technological advancements. However before buying one, you must know all about a pulse oximeter, how it works, what results it give and how accurate they are?
