Is COVID-19 different from other causes of acute respiratory distress syndrome?

Journal of Intensive Medicine, 2023
Coronavirus disease 2019 (COVID-19) pneumonia can lead to acute hypoxemic respiratory failure. When mechanical ventilation is needed, almost all patients with COVID-19 pneumonia meet the criteria for acute respiratory distress syndrome (ARDS).

Individualization of PEEP and tidal volume in ARDS patients with electrical impedance tomography: a pilot feasibility study

Annals of Intensive Care, 2021
Background In mechanically ventilated patients with acute respiratory distress syndrome (ARDS), electrical impedance tomography (EIT) provides information on alveolar cycling and overdistension as well as assessment of recruitability at the bedside.

Differential effects of two-hit models of acute and ventilator-induced lung injury on lung structure, function, and inflammation

Frontiers in Physiology, 2023
Acute respiratory distress syndrome (ARDS) and acute lung injury have a diverse spectrum of causative factors including sepsis, aspiration of gastric contents, and near drowning.

Axon initial segment geometry in relation to motoneuron excitability.

PLoS ONE, 2021
The axon initial segment (AIS) responsible for action potential initiation is a dynamic structure that varies and changes together with neuronal excitability.

Recruitability, recruitment and tidal volume interactions

, 2012
Recent CT-data have shown that lung injury severity assessed by non-aerated tissue, is widely distributed in ARDS population (5 to 70% of total lung weight).

Potential for the lung recruitment and the risk of lung overdistension during 21 days of mechanical ventilation in patients with  COVID-19 after noninvasive ventilation failure: the COVID-VENT observational trial

BMC Anesthesiology, 2022
Background Data on the lung respiratory mechanics and gas exchange in the time course of COVID-19-associated respiratory failure is limited. This study aimed to explore respiratory mechanics and gas exchange, the lung recruitability and risk of ...

PEEP titration according to lung recruitability

, 2013
Bedside PEEP selection methods based on lung mechanics or absolute esophageal pressures provide PEEP levels unrelated to lung recruitability and similar in mild, moderate and severe ARDS, while the oxygenation-based method provided PEEP levels related ...

Association of radiological lung pattern and respiratory mechanics with potential for lung recruitment in patients with COVID–ARDS: a retrospective cohort study

European Journal of Medical Research, 2022
Background The ventilatory management of COVID–ARDS is controversial, especially with regard to the different subtypes and associated PEEP titration. A higher PEEP may be beneficial only in patients with potential for lung recruitment.

Visual anatomical lung CT scan assessment of lung recruitability

, 2013
PURPOSE: The computation of lung recruitability in acute respiratory distress syndrome (ARDS) is advocated to set positive end-expiratory pressure (PEEP) for preventing lung collapse. The quantitative lung CT scan, obtained by manual image processing, is

Correlation between normally aerated lung and respiratory system compliance at clinical high positive end-expiratory pressure in patients with COVID-19

Scientific Reports
Normally aerated lung tissue on computed tomography (CT) is correlated with static respiratory system compliance (Crs) at zero end-expiratory pressure.
