![]() Be sure to keep a check on the battery.Depending on the make of the oximeter, clip it on the finger. ![]() The purpose of the pulse oximeter, for most people, is best served when one is feeling ill and they are deciding whether or not they should go to the hospital.” PRODUCT SPECIFICATIONS: Brand: Generic Dimensions (L x W x H): 1.70 x 1.00 x 0. “It is unlikely because low oxygen levels are a relatively late indicator of a person with COVID-19. There are now apps claiming to be able to calculate the oxygen saturation levels in the blood and doctors warn against the use of these as the accuracy cannot be 100 per cent in such cases.ĭr Mike Hansen, a pulmonologist based in the US, in this video answers the question about whether pulse oximeters are a good early indicator of COVID-19 infection. If you are hale and hearty then there is really no need to invest in the device and keep tabs on the readings. “Use the device if you are already in isolation, or if one has come in contact with a COVID-19 positive person, or experiencing fever and other allied COVID-19 symptoms,” she adds. ![]() Shortness of breath, experiencing a tinge of blue on your fingertips and toes, or other symptoms like chest pain, dizziness, and even a fever accompanied by a cough or a body ache are all parameters we would consider.” Is the oximeter reading the only parameter to monitor when it comes to COVID-19? Stay Home and Stay Safe.ĭr Reubina Kd Singh, a gynaecologist based in Gurugram says, “It is one of the many parameters that we ask you to monitor. Ideally, the device reading should be in the range of 95 per cent to 99 per cent. The pulse oximeter can thus tell oxygen saturation levels as well as heart rate. It measures the light absorption changes in oxygenated or deoxygenated blood. It passes small beams of light through the blood in the finger which measures the level of oxygen. The small clip-like device is fixed on a finger, or earlobe depending on the oximeter being used. The device shows how well oxygen is being sent to those parts of your body furthest from your heart, such as the arms and legs. So what is a pulse oximeter? How does it work? And more importantly, how does one get a correct reading on it?Ī pulse oximeter is a small, non-invasive and painless device that measures the oxygen level (oxygen saturation) of the blood. With a pandemic underway, messages are doing the rounds that a pulse oximeter is a must-have in households, especially with family members with health problems.
