Since the onset of COVID-19, medical professionals have struggled to rapidly diagnose and determine whether someone has the respiratory illness. This issue is particularly acute in hospital intensive care units (ICUs) where doctors and nurses must triage patients based on the severity of their illnesses. Now, a “breathalyzer” test given to critically ill patients has been found to detect the virus quickly and efficiently, providing new hope for the rapid screening of people who are overwhelming hospital emergency rooms. Specifically, the breathalyzer test was found to detect COVID-19 with 88% sensitivity among a group of 46 patients admitted to an ICU.
