COVID 19 Cases
CASE 9-1 1) Covid 19 with co morbidity (Pulmonology/Rheumatology) https://nikhilasampathkumar.blogspot.com/2021/05/covid-pneumonia-in-pre-existing-case-of.html Questions: 1) How does the pre-existing ILD determine the prognosis of this patient? The pre-existing ILD significantly worsens the prognosis of this covid patient. Interstitial lung disease is characterized by dyspnea, decreased pulmonary diffusing capacity, decreased FVC and TLC. The SpO2 of these patients is usually decreased due to increased A-a gradient A superimposed covid-19 infection in these cases can cause an acute exacerbation of symptoms such as dyspnea, decreasing levels of SpO2 further and faster than in Covid-19 patients without interstitial lung disease. Radiology (HRCT) usually shows the development of new pulmonary opacities and fibrosis. Patient factors: Since this patient already had a reduced SpO2 of 90-92% (compared to the normal range of >96%) she is more susceptible to worsening of hypoxia
