His tempo of disease at this juncture is one of worsening and for this reason, along with the reason that it was easier to observe while maintaining respiratory isolation, he was moved to the ICU. He was placed in strict respiratory isolation with personnel entering the room using air-purifying respirators (PAPR) using P100 HEPA filters (filter >99.97% of 0.3 um particles). Preliminary studies suggest a high positive rate for respiratory samples obtained by bronchoscopy. However, with a positive nasal swab for COVID-19 bronchoscopy would seem to add little at this time other than excluding other pathogens. A repeat chest X-ray showed progression of the consolidation. His oxygen requirements gradually increased until he was on a 60% oxygen by mask and he was dyspneic at rest.
