By analyzing the medical records of thousands of patients hospitalized with COVID-19, an American research team led by scientists from the University of Washington showed that low blood oxygen saturation (hypoxemia) and high respiratory rate (shortness of breath) are two predictions Indicators. death. Both can be easily monitored at home.
high Respiratory rate (Shortness of breath) And the lower one Oxygen saturation (Hypoxemia) Representative and Risk of death each Coronavirus disease,by Coronavirus SARS-CoV-2.Since it can be easily monitored at home, and bad clinical results can be predicted, just in case Positivity It is possible to seek help from the hospital before the situation is irreversible.In short, these are two important wake-up calls that, if properly assessed, can help save many lives and protect them from viral infections; in fact, it should be remembered that low oxygen saturation may remain Asymptomatic This is true even at dangerous levels.
A US research team led by scientists from the Department of Cardiology at the University of Washington determined that controlling hypoxemia and shortness of breath at home can save lives and thus avoid COVID-19. The research team worked closely with colleagues at the University of Washington. Chicago Department of Biostatistics and Rush University Medical Center.Scientists led by Seattle University professors Neal Chatterjee and Nona Sotoodehnia analyzed 1,000 patients Between March 1 and June 8, 2020, all people 18 years of age and over were hospitalized with COVID-19, which was the first wave of dramatic infections of the disease. Pandemic.
Among hospitalized patients, about 20% (197) died in the hospital. By comparing all the data, it is found that patients with low oxygen saturation are 1.8 to 4 times more likely to die than hospitalized patients with normal saturation.Those who made Shortness of breath The risk of death caused by shortness of breath or shortness of breath (that is, high breathing rate) is 1.9 to 3.2 times that of a normal breathing person.The hypoxic saturation in this study is equal to 91% Or lower, for shortness of breath 23 breaths per minute or more. body temperature(temperature), Heart rate E blood pressure The study author wrote in an article that they are not factors related to the risk of death. Press release.
Professor Chatterjee and colleagues explained, CDC Indicates that COVID patients must seek medical care when conducting experiments Difficulty breathing E Persistent chest painHowever, as pointed out, even with dangerous values, low oxygen saturation can usually remain asymptomatic. Initially, most COVID patients did not have difficulty breathing. Professor Sotoodehnia said that their blood oxygen saturation may be low, but they still have no symptoms.He added that if people wait for shortness of breath before seeking help, it may be too late to intervene Life-saving treatment.The combination of Supplemental oxygen E Glucocorticoid The authors of the study explained that for patients with hypoxemia and shortness of breath, it can actually “effectively treat severe COVID-19 cases”, but it must be taken as soon as possible.
“We give patients supplemental oxygen to maintain blood oxygen saturation from 92% to 96%. It is important to note that only supplemental oxygen patients can benefit from the life-saving effects of glucocorticoids. “On average, we The oxygen saturation of the hypoxemia patients was 91% when they were admitted to the hospital, so many of them are already far below the life-saving measures we will take. For them, this kind of treatment is too late,” the expert commented.
Based on these findings, the study authors emphasize the necessity of CDC and CDC.WHO Reconsidering their guide, precisely because there are so many Asymptomatic person They may need to be hospitalized. Experts reviewed the importance of the SARS-CoV-2 coronavirus positive virus. Oximeter/pulse oximeter Monitor blood saturation at home and count how many breaths you take in one minute; you can also get help from friends or family to do the calculation. If it exceeds 23 per minute, it is recommended that you contact your doctor.Experts concluded that these tips are particularly valuable for people at risk of severe COVID-19, such as The elderly And those who suffer obesity.
