Supplementary oxygen should be administered to patients with hypoxic respiratory failure for avoiding values of Spo 2 lower than 90%, and it should be aimed at reaching values not higher than 96%. Although still without firm evidence, we currently support the use of CPAP helmet (with gentle ventilation and a PEEP of no more than 10–12 cm of water) if the patient does not respond to standard/HFNC oxygen supplementation and there is no urgent indication for endotracheal intubation (expert opinion). However, no clear indications/criteria can be provided pending further experience. Finally, it should be kept in mind that patients with COVID-19 can get worse in a few hours, so they should be closely monitored for worsening respiratory function so that tracheal intubation and mechanical ventilation can be quickly performed if needed.
