There is one clinical trial.
COVID-19 originated from Severe Acut Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection leads to critical condition due to hypoxemic respiratory failure with the background of viral pneumonia. Both alevolar recruitment and the subsequent optimal positive end-expiratory pressure (PEEP) adjustment has a pivotal role in the elimination of atelectasis developed by inflammation in the lung parenchyma The gold standard of the follow up of recruitment manoeuvre is the chest computed tomography (CT) examination. However, reduction of intrahospital transport and the exposure with healthcare workers are recommended because of the extremely virulent pathogen spreading easily by droplet infection. In this case bedside investigations have an utmost importance in the management of hygiene regulations. Electric impedance tomography (EIT) is a non-invasive, radiation free functional imaging technique easily applicable at the bedside.
