[1] focused on humidification during the collection of exhaled breath condensate (EBC) in patients undergoing invasive mechanical ventilation (IMV). Indeed, in the current guidelines, it is still unclear which standard humidification setting and technique should be used [2, 3]. In some studies, the EBC has been performed with active humidification [4], while others have removed it before collection [5]. Hjembaek-Brandt et al. [1] demonstrated that diverse settings of active humidification may vary the amount of sample collected quite remarkably. The authors concluded that the EBC collection should be performed with no humidification, turning off the humidifier 10 min before starting the exam [1].In patients with #COVID19-related acute hypoxic respiratory failure requiring noninvasive ventilatory support, EBC collection with adequate precautions may be feasible and future studies will be needed to explore this research field https://bit.ly/39OxufF ER -
