Three-month follow-up after severe COVID-19 infection: are chest CT results associated with respiratory outcomes and respiratory recovery in COVID-19 patients?

Background: CT Severity Score (CT-SS) can be used to assess the extent of severe coronavirus disease 19 (COVID-19) pneumonia. Follow-up CT-SS in patients surviving COVID-19-associated hyperinflammation and its correlation with respiratory parameters remains unknown. This study aims to assess the association between CT-SS and respiratory outcomes, both in hospital and at three months after hospitalization.

Facing SpO and SaO discrepancies in ICU patients: is the perfusion index helpful?

Peripheral oxygen saturation (SpO) measured by pulse oximetry is an unreliable surrogate marker for arterial oxygenation (SaO) in critically ill patients. We hypothesized that a higher perfusion index (PFI) would be associated with better accuracy of SpO measurement. We retrospectively collected SaO, SpO, and PFI data for each arterial blood gas (ABG) analysis in a cohort of intensive care unit patients.
