(Early in the coronavirus pandemic, when clinicians first started sounding the alarm about silent hypoxia, oximeters flew off the shelves as many people, worried that they or their family members might have to recover from milder cases of coronavirus at home, wanted to be able to monitor their blood oxygen levels.). Those tissues lose oxygen and stop working, no longer infusing the blood stream with oxygen, causing silent hypoxia. A new study, published in the journal Stem Cell Reports, has explained why many Covid-19 patients, even those not in the hospital, are suffering from hypoxia -- a potentially dangerous condition in which there is decreased oxygenation in the body's tissues. The study has also shed light on why the anti-inflammatory drug dexamethasone has been an effective treatment for those with the virus. Patients who can adjust their position independently and tolerate lying prone can be considered for awake prone positioning. By having a better understanding of these underlying mechanisms, and how the combinations could vary from patient to patient, clinicians can make more informed choices about treating patients using measures like ventilation and supplemental oxygen.
