The correct type and time of follow-up for patients affected by COVID19 ARDS is still unclear. The aim of this study was to evaluate at the survivors to COVID19 ARDS requiring non-invasive respiratory support (NRS) admitted to a Respiratory Intensive care unit (RICU) from March 8th till May 31th 2020 looking at all sequelae via a comprehensive follow up. All patients underwent a multi-disciplinary instrumental and clinical assessment within three months form admission to evaluate all infection related sequelae. Thirty-eight patients were enrolled Lung-Ultrasound (LUS) showed an outstanding discrimination ability (ROC AUC: 0.95) and a substantial agreement rate (Cohen's K: 0.74) compared to chest CT-scan detecting improvement of lung consolidations. Youden's test showed a cut-off pressure of 11 cmH2O ExpiratoryPAP-Continuous-PAP-max (EPAP-CPAP) applied at the airways during hospitalization to be significantly correlated (p value: 0.026) to the increased pulmonary artery common trunk diameter. A total of 8/38 patients (21.8%), 2 of whom during follow-up, were diagnosed with Pulmonary Emboli (PE) and started anticoagulant treatment. Patients with PE had a statistically significant shorter length of time of hospitalization, time to negative swab, CPAP/NIV duration, P/F ratio and D-dimers at follow-up compared to non PE. A comprehensive approach to patients with ARDS COVID19 requiring NRS is necessary. This study highlighted cardiopulmonary impairment related to the ARDS and to the high-EPAP-CPAP-max greater than 11mmHg provided during admission, the usefulness of LUS in monitoring post-infection recovery and the correct identification and  treatment of patients with PE during follow up.
