A study has found that one in 100 patients admitted to hospital with Covid-19 develop a pneumothorax – a ‘punctured lung’.
Damage to the lungs can lead to a puncture, just like it happens in the inner tube of a tyre. As air leaks out of the puncture, it builds up in the cavity between the lung and chest wall, and causes the lung to collapse.
This typically affects very tall young men or older patients with severe under-lying lung disease.
Researchers observed Covid-19 patients not belonging to these two categories, but who had developed punctured lungs.
Data from 16 hospitals revealed an incidence of 0.91 per cent. Just under two-thirds (63 per cent) of patients with a punctured lung survived.
