which lung volumes were affected by the additional dead space? did they increase or decrease?

The changes seen after COVID-19 in this study are roughly equivalent to those associated with 15 years of normal aging, but are still much smaller than those seen in established lung disease. This is something that is part of normal aging in the lung.

Prior COVID-19 infection was associated with more uneven inflation of the lungs during normal breathing.

The participants were studied six months and twelve months after COVID-19 infection, using a novel computational approach to assess lung function.

Those who were admitted to an ICU with severe COVID-19 and in most cases received invasive mechanical ventilation.Those who were hospitalised with COVID-19 but not admitted to an intensive care unit (ICU).Those who had COVID-19 and were managed in the community.Control participants, who had not had COVID-19.The study was based on 178 participants who were grouped into four categories: To investigate this, a study led by the University of Oxford’s Department of Physiology, Anatomy and Genetics used a novel computational approach to assess how COVID-19 may affect long-term lung function. It remains unclear whether these symptoms are associated with any long-term damage that reduces the function of the lungs and respiratory system.

While most people recover completely, a significant number of individuals experience symptoms that can persist for weeks or months post COVID infection, sometimes referred to as ‘long-COVID’. As a respiratory disease, COVID-19 infection mainly affects the lungs.
