Brief Summary

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.

Study Arms (1)

PEEP incremental-decremental alveolar recruitment

EXPERIMENTAL

1. installing EIT belt over the chest at the level of the 5th intercostal space and adjustment of the default recruitment settings in pressure control ventilation mode: pressure control 15 cmH20, PEEP 10 cmH2O, fraction of inspired oxygen (FiO2) and respiratory rate according to the discretion of the attending physician, recording basal parameters 2. implementation of recruitment: * increment phase: increasing PEEP by 3 cmH2O in every two minutes from 10 cmH2O until top of PEEP 25 cmH2O * decrement phase: decreasing PEEP by 3 cmH20 in every two minutes from 25 cmH20 until the basal PEEP 10 cmH20 * end inspiratory hold manoeuvre at every PEEP level 3. recording closing parameters Repeating the above detailed intervention once daily as long as the patient is controlled ventilation.

Procedure: alveolar recruitment

Interventions

incremental and decremental positive end-expiratory pressure alveolar recruitment

PEEP incremental-decremental alveolar recruitment
