Most comatose patients with COVID-19 recover well 'but it can take weeks'

A retrospective study shows recovery is often delayed when patients experience lingering hypoxaemia, critical care neurologists say

Recovery of consciousness may take weeks for patients with COVID-19 who have been on a mechanical ventilator and it is slowest after long-duration hypoxaemia, a study shows.

Critically ill patients with COVID-19 seem to take much longer than the average patient to ‘come to’, an observation that has implications for decision-making on life-sustaining therapies, US researchers say.
