What is a pulse oximeter and can it help against COVID-19? NehaPathakMD explains:
patients have dangerously low levels of oxygen, but appear completely comfortable. This is being called “silent hypoxia.” While other conditions can cause silent hypoxia, the number of people with COVID-19 presenting this way is making some doctors rethink how we manage COVID-19 patients before they need emergency care.
Usually, people with low oxygen levels appear uncomfortable, sometimes even to the point of appearing to be gasping for air. This can happen if the windpipe is blocked or if too much carbon dioxide builds up in the blood triggering your body’s response to breathe faster to breathe it out. , one ER doctor recommended home monitoring for patients with COVID-19 because he believes that information about oxygen levels may help some people seek care earlier if their oxygen level begins to drop.Checking oxygen levels at home is beneficial mostly for those who have diagnosed COVID-19 or symptoms that are highly suggestive of infection. Monitoring your oxygen levels can provide reassurance as symptoms of shortness of breath ebb and flow during the course of the illness.
Because many people are now buying these devices, you may notice short supplies of pulse oximeters. If you do choose to buy one, you can check the FDA website to help you decide what oximeter to buy. Stick with the clip-on versions. Other types may use fancier technology, but they may give inconsistent, unreliable information.If you do notice your oxygen levels dropping, contact your doctor for advice.
