In COVID-19–related ARDS, both a low lung recruitability (L-type) and a high lung recruitability phenotype (H-type) have been described based on lung compliance and the amount of nonaerated lung tissue on lung CT scans (8). /OP false All consecutive mechanically ventilated patients admitted to the ICU with COVID-19 and moderate to severe ARDS (according to the Berlin definition of ARDS) were included in this study. Examples: NFL, Therefore, PEEP should be personalized to maximize alveolar recruitment and minimize the amount of alveolar overdistention. PEEPset did not change significantly over time (Figure 2C). Printer friendly. 0000014196 00000 n At a total PEEP between 15 and 21 cm H2O, ventilation is mainly distributed to the center. The PEEP was reduced an additional 2 cm H2O to confirm a further increase in collapse. The percentages of relative alveolar overdistention and collapse are presented as well. Data were presented as medians and interquartile ranges (IQRs). These PEEP levels did not result in high driving pressure or transpulmonary pressure. However, we did find a significant correlation between PEEPset and BMI (ρ = 0.76; P = 0.001) (Figure 2B). << NASA, The Wilcoxon signed-rank test was used to test the difference between PEEPset and the absolute distance to either the PEEP–FiO2 table and to test the difference in PEEPset between the first and last PEEP trial (up to Day 7). h�bb�e`b``Ń3� ���ţ�1�� ��� endstream endobj 508 0 obj <>/Metadata 54 0 R/PageLabels 50 0 R/Pages 53 0 R/StructTreeRoot 56 0 R/Type/Catalog/ViewerPreferences<>>> endobj 509 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 0/TrimBox[0.0 0.0 589.606 793.701]/Type/Page>> endobj 510 0 obj <>stream Total set positive end-expiratory pressure (PEEP) based on electrical impedance tomography.

This study showed that PEEPset at the level of lowest relative alveolar overdistention and collapse, as measured with EIT, corresponded better with the higher PEEP–FiO2 table in 15 patients with COVID-19–related ARDS.

In addition, PEEP trials did not result in relevant hemodynamic instability or pneumothorax. ‖Highest measured value (in cm H2O) in the first 7 days of admission; DP was calculated as the difference between plateau pressure and total PEEP. Patient survival improved if higher PEEP successfully recruited atelectatic lung tissue (2). Diffuse or focal ARDS was established with chest X-ray or lung computed tomography (CT) scan, similar to the LIVE (Lung Imaging for Ventilatory Setting in ARDS) study (7).

Note: the expiratory and inspiratory values are not necessarily measured at the same time and do not reflect transpulmonary driving pressure. Each marker represents PEEPset at the level of lowest relative alveolar overdistention and collapse as measured with electrical impedance tomography. %���� Driving pressure was below 13 cm H2O in all patients (Table 1).

Electrical Design Calculations and Considerations. 0000020322 00000 n At a total PEEP of 29 cm H2O, the dorsal areas of the lung are mainly ventilated, whereas the ventral parts are not ventilated because of overdistention. In addition, a secondary analysis of the ALVEOLI trial found that higher PEEP improved survival in patients with a hyperinflammatory ARDS phenotype (10). Figure 2. The PEEP was increased stepwise until the PEEP was 10 cm H2O above the baseline PEEP with a minimum PEEP of 24 cm H2O (PEEPhigh), corresponding with the maximum PEEP advised by the PEEP–FiO2 table. 0000002719 00000 n There was no correlation between PEEPset and FiO2 (ρ = 0.11; P = 0.69).

All patients had high concentrations of C-reactive protein and required vasopressors during the first week after ICU admission. Lastly, the total PEEP was set (PEEPset) at the PEEP level above the intersection of the curves representing relative alveolar overdistention and collapse (Figure 1) (6).

Plateau airway pressure and total PEEP were measured during a zero-flow state with an inspiratory and expiratory hold procedure, respectively. The position and balloon inflation status were tested with chest compression during an expiratory hold maneuver. #���. Study protocol. PEEPset was 2 cm H2O (IQR, 0–5 cm H2O) above the PEEP set by the higher PEEP–FiO2 table and 10 cm H2O (IQR, 7–14 cm H2O) above the PEEP set by the lower PEEP–FiO2 table (P = 0.01 for the absolute difference) (Figure 2A). Moreover, response to higher PEEP should always be monitored in terms of driving pressure (2) or oxygenation (11). In our study, the majority of patients had or progressed to diffuse ARDS, based on chest X-ray or lung CT scan. The crosses indicate subjects who died within 28 days following ICU admission. /OP true Only the first PEEP trial of each patient is presented.
